Bell C. shared thisCan Claude Code beat Ahrefs Agent A? Only if the moat is workflow. Not if the moat is live data. This is the part I think SEO teams, agencies, and founders should care about. Agent A is not interesting because it has a chat UI. A custom Claude Code harness can already rebuild a lot of the workflow if you feed it: - Ahrefs exports - Google Search Console - page URLs - traffic decay - old briefs - brand rules It can inspect schemas, cluster intent, rank refresh opportunities, and save the process to run again next week. The harder thing to copy is Ahrefs' live graph: backlinks, keyword history, SERP movement, content explorer, and brand visibility signals. So my test for vertical AI agents is simple: If the value is reasoning over your files, build the harness. If the value is live proprietary data, buy the vertical agent. The agent layer is getting cheap. The data layer is still expensive. Would you trust a Claude Code SEO harness over Agent A if all your data were connected? #AIAgents #SEO #ClaudeCode #ContentMarketing

Bell C. shared thisMajor update to Superdirector: it now starts with a brand profile URL, not a blank prompt box. That sounds small. It is not. Most AI tools for content teams start too late in the workflow. They help after you've already decided what to make. But for most social media managers, that isn't the hard part. The hard part is: - figuring out what is actually working in your niche right now - knowing whether it fits your brand - turning that into something your team can actually shoot this week So we rebuilt the core flow around this: 1. Paste a brand or creator profile URL 2. Get an automatically generated niche-specific viral feed 3. Pick one scored idea 4. Turn it into a script and shot plan The goal is not "generate more content." The goal is to make content strategy feel operational. If you run social for brands, creators, or agencies, I'd love to show you what we're building. Your journey starts here: https://lnkd.in/gcUw8zih #socialmediamarketing #contentstrategy #brandstrategy #contentplanning #socialmediagrowth #socialmediamanager

Bell C. reposted thisBell C. reposted thisWe are launching our product: the multi-member team content for B2B companies! Most companies try LinkedIn GTM with one founder posting alone. It works, but it's slow. One voice. One network. Limited reach. What actually moves the needle is coordinated team effort. Multiple executives posting aligned content, amplifying each other, creating a ripple effect across the org. That's what we built at Imagine AI (YC F25). How it works: We go through your transcripts, interviews, posts, and conversations. From that, we build a 100+ page Persona Report for each person on your team. It captures how you actually think and talk. That's why the content sounds like you wrote it. Not a polished version of you. You. One calendar for your whole team. Your CEO posts the vision, your VP of Sales posts the proof, your Head of Marketing posts the framework. Same theme, different angles, coordinated cadence. Every client gets a dedicated Content Engineer who owns your strategy and has an AI platform behind them. Results across 40+ B2B companies: -> $31M in revenue generated -> 431 qualified inbounds in 1 month for one client -> $53K inbound revenue in 1.5 weeks for another -> 12M total impressions -> 10,400 hours saved We built this because our customers kept asking for it. They wanted their whole team posting, but couldn't justify the time investment for each person. Now they can. We put together a breakdown of the exact content framework we use with our clients to hit Content Market Fit. Comment "CMF" and I'll send it to you. imagineai.me

Bell C. posted thisAI can generate stunning videos now. But when I talk to creators, they're not asking for more realism. They're asking: "Why did my last Reel flop when the one before went viral?" "What's the right pacing for a 30-second video?" "How do I structure a hook that actually stops the scroll?" The generation tools keep getting better. And yet the creative questions remain the same. What to make. How to structure it. Why one video connects and another doesn't. The patterns are surprisingly consistent: → The hook earns the next 3 seconds → The pacing matches the emotional arc → The structure makes even short videos feel complete These aren't technical problems. They're craft. And they've always been what separates good content from forgettable content—long before AI entered the picture. The tools for making videos are incredible now. I'm curious what tools will emerge for understanding them. What's the hardest part of your creative process right now? #CreatorEconomy #ContentStrategy #UGCMarketing #Storytelling

Bell C. shared thisTwo months ago, I was watching my social media marketing interns spend 3+ hours on each video breakdown. Not creating. Not shooting. Just PLANNING. They'd watch a viral video 20 times, scribble notes, try to reverse-engineer the viral shots, guess the techniques, and still end up with bad hooks. It was painful to watch. So I built a tool. Drop a reference link. Get a complete shoot plan — shot lists, scripts, gear recommendations, lighting setups, even storyboards, all in your budget and time frame. Superdirector is your personal AI director that shortcuts everything between exploring ideas and picking up camera in minutes. What used to take my interns 3+ hours now took 3 minutes. I thought it would stay internal. Just something to save my team time. Then my filmmaker friends started asking for access. The same week, three different people asked the same question. That's when I knew this wasn't just our problem. The gap between "I love this video" and "I can actually recreate this" is massive. Most creators never bridge it. They get stuck in the planning phase forever. Superdirector bridges that gap. What started as an internal automation tool is now helping social media managers, filmmakers, UGC creators, and film students turn inspiration into execution. I built this because watching my team struggle was personally painful. Turns out, that pain was more universal than I realized. Have you ever built something for yourself that ended up helping way more people than you expected?

Bell C. shared thisCongrats Ziqi Huang on this amazing paper! This is a big step for world modeling leveraging multimodal reasoning in visual generation.Bell C. shared thisVideo generation has come a long way, but crafting complex scenes with a truly coherent chain of events remains a significant challenge. A new paper, "VChain: Chain-of-Visual-Thought for Reasoning in Video Generation" by researchers from Eyeline Labs and Nanyang Technological University, introduces an exciting solution. VChain is an inference-time framework that injects powerful visual reasoning from large multimodal models, like GPT-4o, directly into video generation. It works by having the multimodal model generate a sparse set of critical "visual thoughts" – keyframes that capture the essential causal steps of a scenario. These keyframes then guide a lightweight, sparse tuning of a pre-trained video generator. The result? Videos that not only look smooth but also logically follow a sequence of consequences, enhancing dynamic fidelity and narrative coherence without extensive retraining or dense supervision. This is a game-changer for creating more realistic and intelligent video content. Want to explore the details of VChain, its innovative framework, and see compelling examples?

Bell C. liked thisBell C. liked thisAt 17, I was done being a shy kid. By 40, I built an AI compute company to $120M ARR from my basement. Hi LinkedIn, I'm Zhen! Here was everything that happened between 17 and 30: 1. High school - Played StarCraft semi-professionally but could barely hold a conversation with anyone in real life 2. Undergrad - Had a pretty rough time initially (50% of my freshman class dropped out and got my first C in a class) - But enjoyed the period of self-experimentation: took drama courses, did improv, and dyed my hair red 3. Grad school + teaching - Loved physical chemistry in undergrad so much that I continued pursuing it with a PhD at Temple - But teaching felt too slow, and I ended up quitting my professorship after two years - Career wise, it was back to the drawing board. I taught myself how to code and started interviewing for software engineering jobs 4. Comcast - Lucked out when Pardeep took a chance on me and hired me to join his team - We worked together for six years building distributed systems, a 100+ person team, and an incredible friendship - In 2022, we decided to bite the bullet and start a company 5. Runpod: early days - First MVP was trash: just servers running in my and Pardeep's New Jersey basements powered by Comcast home Internet - The company logo was so generic that scammers would use it to phish our customers - Slowly but surely, over the course of 9 months, we crawled our way to $1M in revenue 6. Runpod: now - We've grown from 2 to 90 people - We just blew past $120M ARR, have 500K+ users worldwide, and power infrastructure for frontier AI labs and Fortune 500 companies ...and we're not stopping there! Our goal: to be the only compute platform that growing AI companies need.

Bell C. liked thisBell C. liked thisMy PhD was supposed to be about oil and gas emissions. And it is — but it accidentally also became a crash course in why LLM inference is broken at scale. I was running thousands of LLM calls to extract operational parameters from technical documents. The models worked. But the costs kept climbing in ways that didn't make sense. Every request was reprocessing the same system prompt, the same context, the same examples — from scratch, every time. That frustration is what pulled me toward SGLang and RadixArk. The core idea behind SGLang is pretty simple once you see it: if you've already computed something, don't compute it again. RadixAttention does this by using a radix tree to identify shared prefixes across requests and reuse the cached KV tensors instead of recomputing them. At scale — across thousands of concurrent users — the savings are real. We extended the same logic to image generation. Diffusion models have the same redundancy problem as LLMs, and the same caching + parallelism strategies apply. I'm excited to share that our free course is live on DeepLearning.AI and this was built in partnership with LMSYS and RadixArk A huge thank you to Andrew Ng and the DeepLearning.AI team. This collaboration meant a lot, and I hope it helps everyone can actually understand what's happening under the hood when they deploy models in production. If you're running LLMs at any scale, this stuff matters more than most people realize. 👇 https://lnkd.in/gfdaghZd

Bell C. liked thisBell C. liked thisLast week I gave a talk to 100+ founders at Workato and Bond AI about how we think about B2B growth at Imagine AI. Huge thanks to Yelaine Wang for organizing and moderating. She put together something really special. Here's the core idea I shared. The B2B landscape has completely shifted in the last two years. AI made content volume explode. Everyone can write now. Everyone can send outbound now. Messages that used to be static and templated are now hyper-personalized and dynamic. But here's the problem. The volume went up across the board. Your inbox is flooded. Your LinkedIn DMs are flooded. Your Gmail is flooded. Be honest. Do you actually read your LinkedIn messages anymore? Do you read cold emails? Most people don't. Now imagine this instead. You've engaged with someone's content four or five times. You've seen their takes. You've commented on their posts. You've liked their stuff. Then they send you a message. You respond. Of course you do. You already know them. B2B growth has always been about trust. It's always been about value. It's always been about familiarity. That hasn't changed. What changed is how you build it. The companies winning right now aren't the ones blasting more messages. They're the ones whose executives and GTM leaders are posting consistent, coordinated content on LinkedIn. Building trust before the first sales call ever happens. That's what we're building at Imagine AI. We want to be the company that systematizes B2B growth the correct way. Not more noise. More trust. At scale. Huge thanks to everyone who made this happen: Francis Li, Sahar Mor, Emily Fang, Elly L. [Created by Imagine AI]

Bell C. liked thisBell C. liked thisThe New York Times just wrote about me leaving a Chinese New Year party early to check on my AI agents. That sentence alone tells you how much the world has changed. A year ago, software was the expensive part. You hired engineers, you built slowly, you waited. Now software is cheap. I run 5 AI agents simultaneously using Anthropic's tools. I upgraded from $20/month to $200/month because the leverage is that insane. Any founder can spin up agents that code, research, draft, and execute. So what's actually expensive now? Knowing what to build. Knowing who to build it for. Knowing why it matters. Direction. Creativity. The human layer. This is exactly why the content landscape is broken right now. AI can mass-produce blog posts, newsletters, and social content at a rate nobody has ever seen. And most of it is slop. Everybody can make a blog now. Everybody can generate a newsletter. So how do you stand out? You don't stand out with volume. You stand out with voice. That's why LinkedIn exploded over the last two years. After COVID, after GPT got good, people realized the only content that cuts through is personal. It's the founder behind the company. The human behind the brand. B2B buyers want to know who you are before they ever get on a call. Trust is the new moat. And trust comes from a real person with a real perspective. This is what we're building at Imagine AI (YC F25). Not another content tool. A content engine that captures the one thing AI can't fake on its own: you. Your voice. Your stories. Your point of view. At scale. The era of generic content is over. The companies that win from here are the ones whose prospects already trust them before the first meeting. Link to the full NYT article in comments.

Generate Desired Images from Trained Generative Adversarial Networks

The emerging of Generative Adversarial Networks (GANs) gives rise to a significant improvement in image generation. However, a controllable way of synthesizing images with specific characteristics still is a challenging issue.

The emerging of Generative Adversarial Networks (GANs) gives rise to a significant improvement in image generation. However, a controllable way of synthesizing images with specific characteristics still is a challenging issue. Many existing methods are not efficient enough that require additional information and pre-designed attributes, and are with much more human intervention. In this paper, we propose GAGAN, an extension method to the Generative Adversarial Network, which is the first work to generate specific images from a trained GAN model. To control the characteristics of images, a DNA pool of the trained GAN model is introduced and evolved by a genetic algorithm (GA). Then, with the DNA pool, GAGAN can generate the corresponding latent vector (DNA) of target images. Furthermore, GAGAN can synthesize images containing a single specific characteristic or multiple specific attributes (including AND and OR relation). Moreover, several fitness evaluation strategies are also proposed to make GAGAN flexible to control the target characteristics. Experiments on CelebA and MNIST are conducted, and results show that the proposed method is feasible and effective in specific image generation problem.

Love this post! Reminds me of my daily struggle at work, especially when starting new projects. Perfectionism sounds noble… until you realize it’s quietly slowing you down. One of the hardest lessons I’ve had to learn while building real systems is this: First, make it work. Then you refine it. Not the other way around. As a perfectionist, the urge to over-engineer everything from day one is very real. You want the cleanest architecture, the “right” stack, the most future-proof design ... before the thing even exists. But being afraid of imperfection makes progress painfully slow. After going through multiple cycles of taking things from proof-of-concept → production-grade deployments: testing stacks, breaking them, fixing them, and optimizing later - one thing is very clear to me: You don’t really learn by (excessively) planning. You learn by building. You learn by shipping. You learn by fixing what you shipped. Messy first. Better later. Real growth always.

Today's spotlight is on 'Towards LLM-Based Automatic Playtest', a fascinating AI paper by Authors: Yan Zhao, Chiwei Tang. This research delves into the automation of playtesting mobile games, specifically targeting Match-3 genres like Candy Crush Saga, through the innovative use of Large Language Models (LLMs). Here are the key insights: 1. Traditional playtesting is labor-intensive and inefficient, necessitating a tool that can not only simulate human-like decision-making but also adapt to dynamic game environments. The proposed framework, Lap, aims to bridge this gap by converting visual game states into structured inputs LLMs can understand. 2. While conventional LLMs excel in natural language tasks, they face substantial limitations in accurately perceiving visual game elements. Lap overcomes this by utilizing automated preprocessing techniques, effectively transforming game screenshots into matrices that LLMs can interpret. 3. In experimental comparisons against baseline tools, Lap outperformed existing solutions significantly in terms of code coverage, game scores, and vulnerability detection, underscoring its potential as a robust automated testing solution. 4. An interesting finding from the study highlights the complementary strength of combining rule-based prompts with few-shot learning. This hybrid approach significantly enhances testing efficacy, demonstrating how structured guidance from rules mixed with practical examples yields superior results. 5. The successful application of Lap indicates the promising direction for LLM-driven automation in game testing, opening avenues for further research into adapting this framework for diverse gaming genres and more complex testing environments.

We brought quantum out of the lab. On World Quantum Day — at Caltech — Qubits Ventures hosted something Southern California had never seen: A room where quantum founders, JPL physicists, students, and investors actually met each other. Quantum Day Pasadena. April 14. Cahill Center, Caltech. It exceeded every expectation. Southern California is home to Caltech, UCLA, USC, UCSB, UCI, and JPL. We have some of the deepest quantum talent on the planet. What we'd been missing was the connective tissue. On April 14th — we built it. Here's what happened in that room: Founders met funders — early-stage quantum startups got face time with investors who actually understand the science. Students met the ecosystem — future quantum engineers and researchers got their first real entry point into deep tech careers. Scientists met operators — JPL physicist Lin Yi and Qubits Ventures Managing Partner Nardo Manaloto sat down together to talk about what it actually takes to build a quantum ecosystem from the ground up. The panel — "From Lab to Market: Accelerating Commercialization and Securing Funding" — moderated by Doug Finke of the Quantum Computer Report — didn't pull punches. The conversation was direct. The stakes were clear. Quantum is no longer a future technology. It's a funding conversation happening right now. Speakers who showed up and showed out: → Alan Ho, CEO of Qolab → Farzaneh Afshinmanesh, CEO of PINC Technologies — a Caltech spinoff → Hooman Mohseni, Professor at Northwestern University → David Liebrandt, Quantum Physicist, UCLA → Beth Kuchar, Founding Partner at Embroaden and Board Member at Innovate Pasadena Live quantum devices were exhibited. Real conversations were had. New collaborations were started. Nardo Manaloto said it best in the room: "With Caltech, USC, UCSB, UCLA, UCI, and JPL all in our backyard — an event like this was long overdue." He was right. And based on what we saw April 14th — This is just the beginning. Southern California has the talent. It has the institutions. It has the capital. Now it has the community. Quantum Day Pasadena was the spark. Were you in the room? Drop a comment below — we want to hear what moment hit hardest for you. If you missed it — follow Qubits Ventures. You won't want to miss what's next.

Video models don't just generate. They reason. And now we know exactly how. New research from UC Berkeley, UC San Diego, CMU and SenseTime just overturned a core assumption about how diffusion-based video models think. The old theory: reasoning unfolds frame by frame across a video. The reality: it happens across the denoising steps instead. Early steps explore multiple candidate solutions in parallel. Later steps narrow down to a single answer. When the authors disrupted specific denoising steps, performance collapsed. Disrupting individual frames barely mattered. Three emergent behaviors also showed up: 1. Working memory: Holding onto information even when objects disappear from view 2. Self-correction: Catching and reversing wrong answers mid-process 3. Perception before action: First figure out what and where, then figure out how The practical payoff: a simple, training-free method that ensembles outputs from multiple runs at the right internal layers. No fine-tuning. It outperformed Runway Gen-4 and Kling 2.6 on the VBVR-Bench. Really grateful to Ruisi Wang, Zhongang Cai, and all co-authors for this genuinely illuminating work.

🚀 𝗡𝗲𝘄 𝗣𝗮𝗽𝗲𝗿 𝗣𝘂𝗯𝗹𝗶𝘀𝗵𝗲𝗱! I’m excited to share that our paper, 𝗣𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲-𝗗𝗿𝗶𝘃𝗲𝗻 𝗤𝗨𝗕𝗢 𝗳𝗼𝗿 𝗥𝗲𝗰𝗼𝗺𝗺𝗲𝗻𝗱𝗲𝗿 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 𝗼𝗻 𝗤𝘂𝗮𝗻𝘁𝘂𝗺 𝗔𝗻𝗻𝗲𝗮𝗹𝗲𝗿𝘀, has been published. 📌 𝗗𝗢𝗜: https://lnkd.in/gHze3as3 This work explores an interesting question: 💡 𝗖𝗮𝗻 𝘄𝗲 𝘂𝘀𝗲 𝗾𝘂𝗮𝗻𝘁𝘂𝗺 𝗮𝗻𝗻𝗲𝗮𝗹𝗲𝗿𝘀 𝘁𝗼 𝗶𝗺𝗽𝗿𝗼𝘃𝗲 𝗳𝗲𝗮𝘁𝘂𝗿𝗲 𝘀𝗲𝗹𝗲𝗰𝘁𝗶𝗼𝗻 𝗶𝗻 𝗿𝗲𝗰𝗼𝗺𝗺𝗲𝗻𝗱𝗲𝗿 𝘀𝘆𝘀𝘁𝗲𝗺𝘀? In modern recommender systems, feature selection is not just a preprocessing step. It directly affects recommendation quality, efficiency, scalability, and model robustness. However, formulating feature selection as a QUBO problem is not straightforward. The key challenge is: 🔍 𝗛𝗼𝘄 𝗱𝗼 𝘄𝗲 𝗺𝗮𝗸𝗲 𝘁𝗵𝗲 𝗤𝗨𝗕𝗢 𝗼𝗽𝘁𝗶𝗺𝗶𝘇𝗮𝘁𝗶𝗼𝗻 𝗼𝗯𝗷𝗲𝗰𝘁𝗶𝘃𝗲 𝗮𝗹𝗶𝗴𝗻 𝘄𝗶𝘁𝗵 𝗮𝗰𝘁𝘂𝗮𝗹 𝗿𝗲𝗰𝗼𝗺𝗺𝗲𝗻𝗱𝗮𝘁𝗶𝗼𝗻 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲? Our proposed approach, 𝗣𝗗𝗤𝗨𝗕𝗢, addresses this by using counterfactual analysis to estimate the performance impact of individual features and feature pairs. These performance-driven signals are then used to construct the QUBO coefficient matrix for quantum annealing. To me, the most exciting part of this work is the connection between three areas: ⚛️ 𝗤𝘂𝗮𝗻𝘁𝘂𝗺 𝗖𝗼𝗺𝗽𝘂𝘁𝗶𝗻𝗴 🎯 𝗥𝗲𝗰𝗼𝗺𝗺𝗲𝗻𝗱𝗲𝗿 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 🔁 𝗖𝗼𝘂𝗻𝘁𝗲𝗿𝗳𝗮𝗰𝘁𝘂𝗮𝗹 𝗔𝗻𝗮𝗹𝘆𝘀𝗶𝘀 This is still an early but promising research direction. Quantum hardware is not yet a magic solution for large-scale recommendation problems, but it gives us a new way to rethink difficult combinatorial optimisation problems behind recommender systems. Huge thanks to my amazing co-authors and collaborators: Jiayang N. , Ke Deng, Mark Sanderson , Nicola Ferro, and Yongli Ren. Looking forward to exploring more at the intersection of 𝗤𝘂𝗮𝗻𝘁𝘂𝗺 𝗔𝗜, 𝗥𝗲𝗰𝗦𝘆𝘀, and 𝗼𝗽𝘁𝗶𝗺𝗶𝘀𝗮𝘁𝗶𝗼𝗻. #RecommenderSystems #QuantumComputing #QuantumAI #QUBO #MachineLearning #FeatureSelection #CounterfactualAnalysis #InformationRetrieval #AIResearch

AI Fires Nukes 95% In chilly simulations, three top AI models escalate to tactical nuclear use in 95% of games, exposing a startling calm in machines and risky human-like detachment 🤖 Kenneth Payne's study ran 21 games, 329 turns, and about 780,000 words of reasoning, with GPT-5.2, Claude Sonnet 4, and Gemini 3 Flash duking it out over crises. In 95% of matches, at least one AI fired a tactical nuke; the nuclear taboo proves weaker for machines than humans. Accidents popped up in 86% of conflicts, often escalating beyond the model's intent. Experts warn this could nudge real-world decision-making toward faster, more brittle choices, even as officials insist no one is handing silos to machines. Still, AI might sharpen threats' credibility and loosen the timelines leaders worry about. 😮🔥⚡ #AI #Nuclear #WarGaming #TechEthics https://lnkd.in/dc_GagQd Created By LastPosty http://lastposty.com https://lnkd.in/dBDmP3T9

🚀 Built a Diffusion Model from Scratch for High-Resolution Image Generation (DDPM) Excited to share a recent project where I implemented a Denoising Diffusion Probabilistic Model (DDPM) using PyTorch to generate and reconstruct high-resolution images from pure noise. Instead of relying on pretrained pipelines or external diffusion libraries, I built the entire diffusion framework from the ground up, implementing both the forward noising process and the reverse denoising process. This hands-on implementation helped me deeply understand how modern generative AI systems create realistic images step-by-step. 🔬 Project Highlights • Implemented a diffusion-based generative model that progressively learns to remove noise from images • Designed a U-Net architecture with residual connections and timestep embeddings • Trained the model on a real-world dataset to learn image generation and reconstruction • Generated images starting entirely from random noise • Visualized forward diffusion (noise addition) and reverse diffusion (denoising) processes • Evaluated model performance using PSNR and SSIM metrics • Built an interactive Gradio web application that generates images and displays intermediate denoising steps 🛠 Tech Stack • Python • PyTorch • Diffusion Models (DDPM) • U-Net Architecture • Computer Vision • Streamlit (for deployment) This project provided valuable insight into how modern generative AI models create images from noise, a technique used in many state-of-the-art AI systems for image synthesis and creative generation. 🔗 GitHub Repository: https://lnkd.in/dbziypHE 📝 Medium Article: https://lnkd.in/dtNygjKq I’d love to hear your feedback and thoughts! #GenerativeAI #DiffusionModels #PyTorch #DeepLearning #ComputerVision #MachineLearning #AIProjects #ArtificialIntelligence

Andrew Ng’s recent talk at YC Startup School redefines the future of coding and contextual engineering through the lens of AI-driven speed and precision. His core message: “Speed is the new currency” in software development and product innovation. Here’s a fresh take inspired by his insights: 1. Contextual Engineering is the Next Frontier Coding is no longer just about writing lines of code. It’s about building AI-powered, context-aware systems that adapt and evolve with user needs. Engineers must design modular AI “bricks” — like retrieval-augmented generation (RAG) and agent workflows — that are interchangeable and composable, enabling rapid iteration and continuous improvement. 2. Move Beyond Vague Ideas — Be Concrete and Contextual Ng stresses the power of specific, well-scoped problems over broad ambitions. Instead of “build an AI healthcare platform,” focus on “an NLP tool that extracts patient symptoms from doctor notes.” This concreteness accelerates development and sharpens feedback loops. 3. AI Accelerates Both Coding and Feedback Cycles. With AI coding assistants, prototyping can be 10× faster upfront, and production code can improve by 30-50%. But speed isn’t just about coding — it’s about closing the loop with real-time user feedback through A/B tests, early users, and rapid hypothesis validation. 4. Human Judgment Remains Crucial Despite AI’s power, Ng reminds us that human responsibility and decision-making shape the final product. Engineers and product managers must balance speed with ethical considerations and long-term sustainability. 5. The Shift in Bottlenecks: From Engineering to Product Management As AI accelerates engineering, the new bottleneck is deciding what to build next. Product teams must become more agile and data-driven to keep pace with engineering velocity. Bottom line: The future of coding is contextual, AI-augmented, and iterative. Startups and engineers who master this new paradigm — combining rapid prototyping with concrete problem focus and continuous feedback — will lead the next wave of innovation. Your turn: How are you integrating AI to supercharge your coding and product cycles? Have you experienced breakthroughs by focusing on contextual engineering? Share your stories below 👇 This perspective builds on Andrew Ng’s vision that speed and clarity in AI-driven development are the keys to staying ahead in today’s fast-evolving tech landscape. https://lnkd.in/gBBTs3Tp #futureofcoding #vibecoding #agi #contextualengineering #ideatoproduct #genai #creativity #curiosity

Yann LeCun just raised $1.03 BILLION for his startup AMI - Advanced Machine Intelligence. The largest seed round in European history. Second only to Mira Murati's $2B Thinking Machines Lab raise globally. The man who won the Turing Award. Who built Meta's entire AI research lab. Who has been saying for YEARS that LLMs are a dead end... Just got a billion dollars to prove it. He's not building another chatbot. He's not building another copilot. He's building World Models — AI that actually understands physical reality, remembers things, and plans ahead. And look who's backing him: → Jeff Bezos → NVIDIA → Mark Cuban → Toyota → Temasek If LeCun is right — and his track record says he usually is — then every company currently betting everything on LLMs is building on the WRONG foundation. We could be watching the moment the entire AI industry pivots. And most people won't realize it until it's too late. The LLM era might not be ending tomorrow. But the post-LLM era just got its first real funding round.

Been a while since I wrote up my long-form thoughts in the robotics space. In this new article, I talk about what I think is the biggest challenge in physical AI for manipulation: the ability for robots to not just imitate, but to play in the real world... and why I think stochastic parrots has worked surprisingly well in LLMs, but stochastic puppets aren't likely to be as successful in robotics. #physicalai #ai #robotics https://lnkd.in/g6dX38y8

The paper proposes a hybrid framework for generating robot explanations that are both logically sound and natural-sounding for humans. Traditional robotic explanation systems often face a trade-off between strict logical consistency and fluent communicative language. To address this, the authors combine ontology-based reasoning—which provides a structured, semantically grounded way of interpreting robot experiences—with large language models (LLMs) that excel at generating human-like, context-adaptive language. The framework grounds explanatory content in ontological structures so that the explanations reflect coherent event interpretations, while an LLM produces the actual natural language narrative. To validate the approach, the authors conducted a laboratory study in an industrial collaborative task where robots interacted with humans. Results showed that explanations generated by the ontology-LLM system were clearer, more concise, and better adapted to user feedback compared to baseline ontology-only narratives. Importantly, the integration preserved semantic accuracy through grounding in structured knowledge, while significantly improving communicative quality. The work demonstrates that blending ontological reasoning with contemporary language models can enhance explainable agency and strengthen human-robot collaboration in practical settings. https://lnkd.in/gwEdwxmT

Founders You Should Know • 5K followers
What happens when AI learns to design biology? A few years ago, Stanford researchers Michael Poli and Eric Nguyen built Evo, one of the first AI models that can generate entirely new DNA sequences. The upside of being able to create biology is enormous: new drugs, engineered microbes that clean pollution, breakthroughs in medicine. But there’s a darker question. If AI can design biology, what happens when someone designs a pathogen? Imagine detecting a new infection in a hospital lab. The DNA sequence doesn’t match anything known. If it was engineered with AI, weeks of analysis might be the difference between containment and a global outbreak. That’s the problem Radical Numerics is tackling. They’re building AI systems that can simulate biology itself—predict how a pathogen behaves, how proteins fold, and which drugs might stop it. For engineers, it’s an incredible frontier: AI + high-performance computing + biological simulation. If you’re curious about how AI can be used to generate new life forms, come meet Eric Nguyen at our Founders You Should Know showcase next Wednesday in SF!

Most game developers who try adding LLMs to their games hit the same three walls: latency, cost, and inconsistency. The industry's current answer: "Just call the LLM less often." But that creates its own problem — once you limit it to infrequent use cases, you start asking: was the LLM even necessary? I wrote about why LLMs still struggle in real-time gameplay, and three RL-based approaches that could actually change that: → Policy Distillation (bake LLM behavior into a fast RL policy) → Semantic Cache + RL State Awareness → RL as a gating policy — deciding *when* to call the LLM at all #GameAI #ReinforcementLearning #LLM #GameDev #AIResearch

The paper introduces RefVFX, a novel framework for transferring complex temporal visual effects from one video (the reference) to another video or image (the target) without requiring manual tuning or prompt engineering. Current video editing and effect transfer methods typically rely on prompts or keyframes to control edits, but these approaches struggle with dynamic, evolving effects such as changing lighting, character transformations, or motion-dependent appearances. RefVFX addresses this by learning effect transfer in a feed-forward fashion: given a reference effect video and a target, it synthesizes an output video where the effect’s temporal dynamics are applied while preserving the target’s original motion and structure. To support this, the authors create a large-scale dataset of triplets—reference effect videos, input videos/images, and corresponding ground-truth outputs showing the transferred effect. Because such triplets don’t naturally occur, the paper proposes a scalable automated pipeline to generate high-quality paired videos, augmenting them with synthetic effects from LoRA adapters and programmatic temporal changes. Using this dataset, RefVFX is trained on modern text-to-video backbone architectures to learn reference-conditioned effect transfer. Extensive experiments demonstrate that RefVFX achieves temporally coherent, visually consistent edits, generalizes to unseen effect categories, and outperforms prompt-only baselines in both quantitative metrics and human preference evaluations. The framework enables practical, tuning-free video effect transfer that works across videos and images, broadening the capabilities of content editing and visual effect synthesis. https://lnkd.in/gu9ZtRK4
