its true, Anthropic really vibecoded their entire backend to Rust and none of you noticed
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 on real traffic. CPU dropped 40-50%.
Pretty sure "never do the big rewrite" is dead advice.

community note mfs trying to quote my own show notes back to me, bitch dont cite the ancient magic, i was there when it was written nitter.cf/latentspacepod/status/…
How Anthropic ships Claude with Claude
latent.space/p/opus55/
Opus 5.5 is the #1 LLM in the world right now. We go behind the scenes of the launch, with @katelyn_lesse and @angjiang, heads of Eng and Product behind the platform used to build everything from the first party harnesses like Code/Tag/Duet and by >50% of Anthropic's top customers!
I wrote about this in AINews last night but basically aie.codes is gathering the top 1000 AI Engineers to 1) accurately represent the 2026 SOTA in AI x Code, 2) preview 2027.
So proud to have gathered the best collection of invited attendees, speakers and sponsors to reflect the three themes that have defined this year:

Introducing Phonic-1, the most advanced speech-to-speech model for agentic tasks — from @phonic_co, the speech-to-speech model company.
We’ve had a breakout year and raised a $27.5M Series A led by @firstround with participation from @Lux_Capital, @felicis, and Definition.

our team has been heads down building for years and I'm just so grateful for the response to Phonic-1's launch yesterday
I love my team. they built a model that's..
#1 on AA's speech-to-speech index
#1 on AA's 𝜏-Voice (agentic performance)
#1 on Sierra's τ³-Voice
#1 on Cekura's s2s benchmark
#1 on Veris's VAmoS Pro Bench
#2 on Bluejay's MIVAS s2s benchmark
we literally just dropped seven figures on a new compute cluster to support the load
we can't wait to continue pushing the frontier for our customers!! try it out and let me know what you think

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 AND social.
Introducing celld: a self-hosted, distributed Durable Objects and Workers implementation
- celld = V8 + S3 + SQLite + LTX+ Tokio
- programmed with exactly the Cloudflare Workers/DO JavaScript APIs and config
- order of magnitude cheaper at scale
- writes are durable before they're acknowledged, RPO=0
- only depends on an S3 compatible bucket - no other infrastructure
- ~4 MB memory per cell instance overhead
- hibernated cells cost ~nothing, just their S3 storage
- open source, Apache 2 licensed
even the AIE CODE expo is insanely stacked, basically all the top coding agent companies in the world, i could just wander around all day and catch up with everyone
2 spots left for gold and silver btw - [email protected]
see you in 2 weeks!
last but not least, if you wanna see what else i'm cooking + enjoy techies with extreme musical talent, we're doing v2 of our Broadway show the weekend of: partiful.com/e/e0ePVVLYt7Rn8…?
join in! love u

excited for @Cloudflare's debut as a frontier lab
#NothingButNET gang, assemble!
inspired by High Taste Testers convo with @thaiscbranco_ of @tastelabs btw who gave me immediate critique lol
at spacex ipo everyone was posting their cursor bag fumble.
kid stuff.
my turn.
i estimate this was a $500m bag fumble lol. and very probably wouldve been on claude code early (bc i've been a typescript cli maintainer). fml.
will you buy $ANT stock at a $2T valuation?
14%Yes, significant % of NW
23%Yes, "average" investment
38%No, its for retail chumps
