Introducing Relace Search, a utility agent designed for fast codebase retrieval. RAG is fast because it's fully parallelizable. Agentic search is accurate because of its multi-shot reasoning. Relace Search does both. It calls 4-12 grep and view file tools in between reasoning

It would cost a lot to deploy the instant apply model before, But the @relace_ai exposes the instance apply api directly, which is a game changer for people who build coding agent Congrats on the raising! 🔥

Congrats to the @relace_ai team on the raise! 🎉 If you’re building anything that edits code with LLMs, you’ve probably already used their models without knowing it. Relace provides a specialized “apply” model built just for merging edits, and it’s insanely fast (10k tok/s).

Go go @relace_ai - one of *the* most dialed-in, talented teams out there building the models that power coding agents. Congrats on the raise @pfactorialz @EBorgnia and the whole team, great to see this support from @a16z and @matrixvc.

For decades, code was written by humans. Now, it’s generated by agents. The bottleneck has moved: from writing code to running it. @relace_ai is building the infra that makes coding agents production-ready We’re proud to lead their $23M Series A. @EBorgnia @pfactorialz

We are in a full infrastructure rebuild of the softwares stack. Large models are important, so as fast, purpose-built models to meet the demand of coding agents. That’s what you get from @relace_ai : instant apply, reranker, embedding models and more, for all your coding needs.

Every digital artifact can be expressed as code and code gen is coming to every digital product. Preston and Eitan are building lightning fast models and infra for devs implementing coding agents. Privileged to work with this supremely talented team alongside friends at a16z!

[New Investment] 🚨 We @a16z are excited to lead @relace_ai's series A Everything online - this site, every app, every button - is made of code. Now code can be generated on demand That shift needs new models + infra for real-time creation. That’s what @relace_ai is building 🧵
