From Karpathy's various interviews I get the impression that he wants to leave the door open to working for Musk again at some point, perhaps on TeslaBot.
With Musk for now regarding Anthropic as a partner (or at least an enemy of his enemy), that seems to mean that Karpathy joining them is less likely to anger Musk than might otherwise have been the case. Who knows, maybe Karpathy was involved in brokering this data center deal?
Compare and contrast with working at OpenAI, Google, etc.?
- best harness overall (well maybe until like a month ago when gpt5.5 and codex came out)
- acquires bun
- acquires stainless for SDKs
- deal with Elon for compute
- karpathy
what else did I miss?
All gone, for shitty typeahead
2. Mixed for the entire bun ecosystem, especially with the Rust, Anthropic-focused rewrite
3. Good, because Anthropic's SDK was one of the worst ones to use.
4. Deal with the guy that has a shit ton of compute around wasting money because no-one uses Grok and was frequently calling Anthropic "Misanthropic".

5. Glorified marketer whose probably greatest achievement in pushing AI forward was instructing on CS 231n and coining the term vibe coding.
Yeah, on a roll.
1. Claude Code is widely used and beloved despite not benchmaxxing on the terminalbench like these harnesses that nobody has ever heard of or uses.
5. Karpathy's contributions are way more than CS 231n and coining vibe coding. In terms of pedagogy, his "zero to hero" videos, nanoGPT, etc, are all great. For actual work, he also built a great org at Tesla.
(I also assume they gave him a ton of independence in R&D)
