the solution? it’s not better video models. it’s world simulation models like google’s genie 3. genie doesn’t just predict pixels – it simulates physics rules. gravity, collision, momentum. it understands that when you climb a ladder, your hand grips, your foot lifts, your

I just listened to it and wholeheartedly recommend it. @karpathy
’s exposition is very informative and aligns well with what most hands-on scientists and engineers believe. -
Prioritizing Knowledge Reduction Techniques Over Terminology
By
–
I’m more interested in reductions than what one calls it. Knowledge of reducing, eg of dagger to distillation, can be very helpful to decide what to do with a finite compute budget.

AI 2025: From Prompts to Purpose with Autonomous Agents
By
–
AI in 2025 won’t be about prompts, it’ll be about purpose. We’re moving from reactive systems to autonomous agents that sense, reason, and act independently. Mastering AI now means thinking like an Agentic Architect, someone who designs systems that learn, adapt, and

This made me think of the "Meet in the Middle" paper https://

When I remember correctly, they run two LLMs in both directions with parameter sharing. So it shouldn't impact training time. Kind of wild but hey why not. -
Reading Papers Thoroughly and Training Base Models
By

Thanks for sharing! I need to read the paper in more detail so I don't ask these questions that are maybe already answered in the paper . Regarding your second point, that's a good idea. I think this is especially relevant because many based models (like Qwen3) are trained on

Formal RL Problem Definition and RLHF Practice Discussion
By

Thanks, @CsabaSzepesvari
. Would you mind formally defining the RL problem for everyone here (I know you can better than most). I’d love for us to start with the formal definition and address the practice of RLHF in that context. In particular in most of RLHF, the states -
