The Nvidia paper came down to this: remove synchronization barriers. DeepSeek has already done that with DeepEP (which this paper cited) one layer above. https://huggingface.co/papers/2607.16100 Nevertheless this is great. More users will benefit from this: Nvidia NCCL > SGLang/vLLM DeepEP

Every Microsecond Matters: Achieving Near Speed-of-Light Latency in GPU Collectives

This is definitely a minority opinion. World model MIGHT be the answer to enterprise AI. https://arxiv.org/abs/2602.23643 * Tacit knowledge won't be captured in words, much less accessible dataset * RL is not efficient at all, and labeling gets more and more expensive * AGI won't cover your specialized tasks PS: paper folks you missed one from Yann LeCun!!

Hi, it's been a while 🤗

K3 stunned the world (again). But if you followed my post on K2, the architectural lineage is super clear

I will next discuss the K3 optimizer (Muon again)

GPT 5.1 codex didn't make SOTA either. This should conclude 2025. No model has ever reached above 0.8.

Can this leaderboard be saturated in 2026?

I am starting a new series on matrix. The idea came to me when I wrote about the Muon optimizer.

Matrix itself has lots of fascinating properties and is applied in STEM fields for many decades. Its application in ML is just the beginning. There are lots of low hanging fruits. At the very least, I hope this math perspective will give you a new lens.

DeepSeek v3.2 is worse than R1. This is quite puzzling. Why the regression with new GRPO and new attention?

I used reasoning mode against DeepSeek API

Hard-earned lessons to land your agent (some mine, most learned from others)

1. Clarify expectations. what do you mean by automating emails? auto drafting? replying via templates? extracting details into json?

2. Get access to your customer's corp/prod environment. Guest or sandbox won't cut it, much less your demo account.

3. Don't expect your agent to be turn-key. It will take at least a quarter to stabilize, if your customer actually uses it.

Claude Opus 4.5 didn't make SOTA either. So many models are stuck at 0.75 now

The second point re Ilya post is about RL pain point, i.e. sparse reward. I'm optimistic on this front.

Our actions are driven by unspeakable instincts, which left no traces in training set (pretraining or synthetic). These process rewards (motion sensing, vision etc.) help you master new skills quickly, like biking. Outcome reward only (falling off the bike) is indeed too sparse.

But lots of tasks can benefit from outcome rewards alone. Many latest RL works to upgrade SQL skills use success-failure reward only, with executable as optional reward.

Additionally, scale is the secret sauce for models to surpass humans. A human agent can learn a task quickly, but is capacity limited. But a model agent can process tasks in the scale of many human lifetimes. This made up for the inadequacy of process rewards.

Many such tasks happen to be economically viable, i.e. salary-making jobs.

Ilya's interview has been widely cited. I won't address meta points but share 2 cents on two mundane issues.

I will start with the leaderboard phenomena. This is a feature, not bug. Model training is a project under founder mode. But still like all projects, it needs north stars. And you guess right, (famous) leaderboards are the north stars.

For those startups which found PMFs, many maintain their own proprietary leaderboards/benchmarks condensed from user traffic. The path is blocked on both directions: startups won's share their moats, model makers won't prioritize either.

So instead of complaining, we should celebrate that our prompts work (most of the time)

Grok 4.1 didn't make SOTA, but improves a great deal over 3.

Members of the 70% club are the 4 big players (GPT, Claude, Gemini, Grok) and Kimi.

No SOTA from Gemini 3 either 😖

If RAG (by that I meant vectors and embeddings) transitions from QA to agents, is scalability (from wikipedia to personal memory) still an issue? What will be the new challenges?

Anyone care to share experience?
