swyx is an AI engineer, writer and developer known for the Latent Space podcast and for commentary on AI engineering practice. His recent posts covered MIT's Alex Zhang on recursive language models and how Claude Code, Codex and Pi compare; Anthropic rewriting its Messages API in Rust with Claude writing the code and CPU dropping 40-50%; Gemini topping the Artificial Analysis index; DeepSeek V4.1 Flash serving throughput; and his own notes on low-effort prompting and using Opus 5.5 to estimate work.
uhhh what, 3x faster 5x cheaper but evals SAME ON FRONTIERCODE 2 this is distillation without tradeoffs. i think @thinkymachines inkling is one of the most underrated base models in the world. expect to see a TON more of these esp on US pretrained models [Quo…
i'm still processing. what an insane run. $0 to $100B ARR in 2.5 years. [Quoting @latentspacepod]: hey @TBPN you dropped this but we gotchu
i actually respect breadth in an economy that only respects b2b saas competitor: we solved coding oai: here’s sora competitor: we solved alignment oai: here’s scarlett johannson’s voice competitor: we are giving tokens and vms away for free to recapture mains…
> we developed and trained Ripple-65B Preview for only $32M, which is one-tenth the cost of the previous open-weight SOTA on agentic coding¹ this is like the avengers of open model SOTA ¹ "Note that $32M is our full R&D cost starting from scratch, including p…
lmaoooo [Quoting @latentspacepod]: Recursive Language Models: Claude Code, Agent Swarms, Big Research Bets, & the $40M AI Problem Solver MIT’s @a1zhang explains why Claude Code, Codex, and Pi are basically the same, how RLMs use code, context offloading, and…
join me all the way on the light side guys low effort + critique loop > superultramaxhighwhatever (for the throughput-constrained; see swyxio/skills/babysit-runs) [Quoting @theo]: Julius convinced me to move from extra high to high on Opus 5.5 a week or tw…
its true, Anthropic really vibecoded their entire backend to Rust and none of you noticed [Quoting @somi_ai]: Anthropic rewrote its Messages API in Rust. Zero Rust devs on the team. Claude wrote the code. Humans wrote the plan and checked old vs new matched o…
celld/DOs are awesome. added an old school irc chat channel to my blog recently and realized that you can literally add chat to every interface for actually $0 (as in free) with a good local dev experience now you never have to read alone. the web can be open…

Gemini #1 on AAv5??? this is making me open up @antigravity for the first time in a long time. i’m getting an early review, will report back soon. if google actually pulls this off it is officially comeback season with Meta, Grok and now GDM being cool again.…
psa to all vc’s trying to slide in our dms [Quoting @trq212]: I’ve left Anthropic after more than a year of working on Claude Code and seeing it scale larger than I ever imagined. I have really loved working at Ant and believe deeply in the mission, and most…
fake news btw i got him [Quoting @ArfurGrok]: ✅ Sunil Pai (@threepointone) has joined Anthropic.
*taps sign* read your own emails your apps send out. particularly if they are being vibecoded. real humans still care and do read them. [Quoting @JohnPhamous]: going viral email before // after
imo this is the right attitude - dont blame AI for finding the bugs, just fucking lock in on clearing all the bugs asap [Quoting @JulianPani]: The folks at @latentspacepod with the perfect take, as usual:
Opus 5.5 is the best work estimator model i've ever used. This is calibration that is increasingly important as we delegate more and more work — don't tell me that it's going to take 2-3 working days (what a human would do) when for you, an enthusiastic, inde…
deepseek posted way more alpha on their zhihu page, if you only read twitter you are reading the laowai approved stuff "Based on this framework, we have implemented a high-throughput, low-latency large-scale inference service for DeepSeek V4.1 Flash. Currentl…
underrated podcast. i dont understand the twitter algorithm, u guys are sleeping on some real bangers [Quoting @mariogabriele]: Before investing in Anthropic, Jaan Tallinn asked Dario to line up alternative proposals from VCs. The reason: he wanted confidence…
Data engineers > AI engineers there's a big difference between a "RAG guy" and a "Data Intensive Applications" person like in this screenshot and there's never been a starker difference in demand in my entire career in tech (aka post search engine wars) if yo…
ok i really need the prompt(s) for this video because this is near-kurzgesagt level clarity of explanation (not yet illustration) [Quoting @sweis]: CLAUDE FOUND THE SEEDS
one of the best parts of my job is bringing out the best in ai in each city i love new york ♥️ [Quoting @aiDotEngineer]: We're excited to announce our AI Engineer New York speaker lineup! Presented by @arizeai CEO @ExaAILabs CTO @tryramp CEO @ValsAI CEO @Rogo…
btw dont forget the "one more thing..." theyve been working on dots for a while now [Quoting @OpenAI]: Introducing dots, powered by GPT-6 Astra. Remarkably capable, always-on agents built to handle everything.
more conferences could implement this. so much high value time wasted without thought
Jev pod tomorrow subscribe on apple /youtube @latentspacepod thanks to @allenpark and Ke for making this happen! [Quoting @CompleteSkeptic]: After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last…
