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. Katelyn Lesse on Latent Space: AI... show more

@katelyn_lesse @latentspacepod true for most teams. Anthropic's the last place that loses access to Claude

@katelyn_lesse @latentspacepod The advice "never do a big rewrite" applies to different systems. If all business logic is contained in the source code and there is 1:1 mapping of functions or easy addition of necessary functions then why not?

@katelyn_lesse @latentspacepod I mean, it depends on your service and token budget the bun rewrite cost $165,000 in tokens there are only so many services that are worth a $100K+ rewrite

In the future, you’ll be able to accomplish a goal by just giving Claude an outcome and a budget. That’s the direction Anthropic is building in with its new Managed Agents features, announced at this week’s Code with Claude developer event. The basic idea: Claude, wrapped in a computer in the cloud, that you can spin up, scale, and manage as needed. Anthropic is taking on the infrastructure that kills most agent products, and making sure that it scales to meet the needs of agents running 24/7. On this week’s AI & I from Every 📧, I talk with Angela Jiang (Angela Jiang), head of product for the Claude platform, and Katelyn Lesse (Katelyn Lesse), head of engineering for the Claude platform, about what Anthropic is building and what it takes to make agents reliable in production. We get into: - Why the "build a generic harness, hot-swap any model behind it" playbook is already outdated. Angela points to eval data on Memory where the same task across different harnesses performed drastically differently. - The infrastructure wall every team hits in production—and why Katelyn thinks “my sandbox died and took the agent with it” is the real reason internal agents don't ship. - Why Anthropic is so bullish on using file systems and skills within Claude, including Angela's argument that those early design choices can compound for years. This is a must-watch for anyone trying to take an agent past the demo and into production. Watch below! Timestamps: How the Claude platform evolved from API to agents: 00:01:48 The primitives that make up Claude Managed Agents: 00:04:09 Why the harness and the model are becoming a single unit: 00:10:37 The infrastructure wall that kills most agent projects in production: 00:18:49 Why team agents need a different shape than individual productivity tools: 00:24:49 How Anthropic's legal team uses an agent to review marketing copy: 00:26:36 Using multi-agent orchestration for advisor strategies, adversarial pairs, and swarms: 00:34:24 How to measure agent success with outcome and budget as the end state: 00:35:50 What the platform looks like a year from now, when Claude writes its own harness: 00:39:11

Boris Cherny, Head of Claude Code at Anthropic: "The next transition is coming this year." 2023: you wrote the code. 2024: you prompted Claude to write the code. 2025: you wrote loops that prompted Claude. 2026: you build the harness that runs the loops. Each transition, the engineers who understood the new abstraction first moved ahead permanently. The ones who waited caught up eventually — but never all the way. Harness engineering is the 2026 abstraction. Here is everything you need to know ↓

this YAPPER ad is 100% AI and claude code did 90% of the work all i did by hand was trim the clips it's a rebuild of a real viral organic post: a perfume brand employee ranting in her parked car on her lunch break. what claude code did on its own: - wrote the script with my copywriting skill and swipe library, modelled on the original beat for beat - turned one real frame from the original video into a completely new person in ONE edit - generated 26 Omni takes from that exact frame with her mannerisms copied take by take: the eyebrow raise on the big number, the side eye out the window, palms out for "business mode" - built the edit: stickers, captions, fine print, and the audio matched to a phone mic in a car so it doesn't sound like a studio - checked its own work: camera drift locked, stray words flagged, every take's voice level-matched the one thing i still do myself is the jump cuts. AI cuts on the pause, a human cuts on a blink, and that's what makes it feel real RT + reply 'YAPPER' and i'll send you the full workflow (must follow so i can DM)

Message threads are now in public beta on the Messages API. The API caches your conversation on the server between turns, so instead of resending the full conversation, you send only new messages and the previous message ID, and Claude starts responding sooner.

Agent Zero crushed Codex by 2.6× on token efficiency! We gave both agents the same task on the same local model (Qwen3.6 27B): build a retro Q*bert arcade game. Each agent wrote and rewrote it across iterations, adding enemies and a HUD. Outputs: • Agent Zero: 239K tokens, 53 min • Codex: 627K tokens, 51 min Both agents built a working Q*bert, but Gitlawb 's Agent Zero is the cleaner build, with crisper textures and hops that land where they should. Codex refills the context window with its whole history every turn, so the model loses the thread and hallucinates code it never wrote. Agent Zero sends only what's new, so it keeps more of the window open and makes fewer mistakes. Run agents on local AI models in Atomic Chat!

Anthropic CEO: “ I have engineers within anthropic who don’t write any code, they just let Claude write the code and they edit it and look it over” “At anthropic writing code means designing the next version of Claude it self, so we essentially have Claude designing the next version of Claude itself, not completely but most of it”. In the last 52 days, the Claude team dropped 50+ major feature launches. This is literally INSANE.

Folks are not fully understanding just how important Zero—Human Company understanding is. Our human egos require “human in the loop”, the reality is Anthropic doesn’t need it and they just said it. Claude wrote 100% of Claude. - Mike Krieger, Chief Product Officer, Anthropic:
