Yuchen Jin is an active AI commentator on X who writes about model performance, open-source access, and safety approaches. Recently he discussed Jev’s claim of an AGI-class model that is 20–200x faster and 40–400x cheaper, compared DeepSeek V4.1 versus GPT-5.6 on coding/agent benchmarks, voiced hope for an NVIDIA open-source model, and noted preferences for Codex and Kimi K3.
We rolled out GPT-6 Astra to every Databricks engineer today. It beats Claude Opus 5 on the hardest, long-horizon tasks and increased our coding spend by 60%. I think it’s the strongest model. Expensive. But hopefully worth it. [Quoting @pwendell]: Today we r…
Any guess what this Union Alpha beast on OpenRouter is? Claude Fable 5.1-level, over 10x cheaper. Waiting for it to be open-sourced. https://t.co/okoQnHeMw6
Jev has spoken. It picked which model is AGI. 20–200x faster. 40–400x cheaper. This could make things like LLM-as-a-judge insanely fast and nearly free. (I tried a bunch of prompts and still didn’t burn through $0.10.) https://t.co/1Uhh4nMGDl [Quoting @Comple…
Zuck’s AI safety take is basically the opposite of most frontier labs: Most labs: The more powerful the model, the more dangerous it is, so access should be restricted. Zuck: The more powerful the model, the more dangerous it is to let a few labs control it.…
Jensen is the most based man in AI. I really hope NVIDIA builds a frontier OSS model.
It’s been 23 days since I last opened Claude Code. It used to be one of my favorite products, but I think I prefer Codex now. Codex just works better with OSS models. And among OSS models, Kimi K3 is still unbeatable at coding.
My friend sent me this after seeing the 4 big AI labs agree to “pace the frontier”: “Remember the top students in our school? They always said they never studied after school, but they were somehow always top 3 in every exam. Did you believe them?”
Banning open-source models would be the worst possible outcome of “pacing the frontier.” Geohot once made a compelling point: why can one man control an entire chicken farm? Because he’s smarter than the chickens. If 1 or 2 frontier AI labs control all the in…
It’s shocking that Dario, Elon, and Sam all agree today that we should slow the pace of AI. I’m generally supportive of embedded third-party evaluators, but I have a few concerns: 1. who evaluates the evaluators? How do we make sure groups like METR remain fa…
First time I’ve seen Sam agree with Dario since Anthropic was founded. [Quoting @sama]: I agree with Dario that we need to pace the frontier. This has been a primary topic of discussions we've had at OpenAI in recent weeks. Committing to having independent ev…
25 Fields Medalists are worried AI solving math too fast could damage mathematics. I see the opposite happening in coding. Imagine scientists delaying a cancer cure by 100 years just so they can experience discovering it themselves. It would be a disaster for…
5 months at Databricks. I do not say this lightly. Our AI inference is getting too fast. We are extremely close to the model answering before you finish typing the prompt. We are not asking for a ban. We are asking for a pause.
DeepSeek V4.1 Flash is beating GPT-5.6 Sol on coding and agent benchmarks, while being ~97% cheaper. Another 4× reduction in KV cache size per token is super impressive. This is the era of open source AI. Databricks will be bringing it to our customers soon!…
