Social Media Summary

OpenAI dominated headlines as Sam Altman announced a town hall for AI builders, seeking feedback on new tools—a significant developer relations move drawing massive engagement. Meanwhile, foundational AI debates intensified.

  • Yann LeCun (Meta) argued forcefully that auto-regressive LLMs don't truly reason or plan, calling token-based search inefficient compared to latent-space reasoning
  • Geoffrey Hinton urged politicians to take AI regulation seriously before dismissing it as interference with innovation
  • Ethan Mollick made waves observing that developers managing AI agents are rediscovering classic management theory problems around delegation and goal-setting

Claude Code saw heavy discussion: async hooks shipped for background execution, Jerry Liu (LlamaIndex) revealed it's their top weekly contributor, and Andriy Burkov critiqued its grep-based code search causing duplicate implementations. Demis Hassabis announced Google DeepMind expansion into Singapore, while Nathan Lambert released comprehensive single-GPU RLHF training scripts covering modern algorithms.

Yann LeCun provides detailed technical explanation: auto-regressive LLMs don't reason/plan, token sequence search is inefficient, actual reasoning requires world models and optimization in continuous space, not discrete token search.

@deanwball @neqyve @ThomasRodskog No. I'm saying several things but not that. I'm saying 1. *auto-regressive* LLMs don't reason and don't plan 2. LLMs with token sequence search bolted on top can inefficiently perform reasoning for domain where reasoning can be done in token space (essentially math and code) 3. Actual planning and reasoning requires a search over answers/outputs (by energy minimization). This (a) requires a *world model* (LLMs are not it), and (b) is much better done by

This game was 100% designed, tested, and made by Claude Code with the instructions to "make a complete Sierra-style adventure game with EGA-like graphics and text parser, with 10-15 minutes of gameplay." I then told it to playtest the game & deploy. Play: t.co/JuqRUYQXc0 t.co/LgK0HQWRDf

Ethan Mollick observes that AI practitioners delegating to coding agents are rediscovering classic management theory problems around delegation, goal-setting, and coordination.

As a business school professor, its striking that a lot of the AI folks on this site, as they increasingly delegate authority to coding agents, are re-encountering the basic problems that underlie management theory and practice. Many delegation problems are old & well-understood!

Andriy Burkov analyzes Claude's coding strengths and key limitation: myopic grep-based code search leads to duplicate implementations and irrelevant fixes as codebases grow.

Source details
Claude is great at coding. Like really, really good, compared to using a regular LLM like Gemini. There's only one issue with it. Because it never sees the full code of the app but uses grep search for relevant code snippets, it's myopic. If grep returns a fragment of code similar to the bug description, it often doesn't look further and fixes an irrelevant part of the app or answers a question based on these fragments found by grep. So, as the codebase grows, it becomes important for the use

Exciting addition to the RLHF Book on my DGX Spark arc is a bunch of single GPU, tinkering scripts for minimal examples of RL, reward models, etc. (and DPO like algorithms soon). Right now has REINFORCE, RLOO, PPO, GRPO, Dr. GRPO, GSPO, CISPO, standard reward model, PRM, ORM. H/t to Zafir Stojanovski an independent researcher for doing a lot of the groundwork. Would really welcome issues, contributions, and suggestions as we build the RLHF book as a more central home for learning about post-t
