Anthropic 发布 Claude Sonnet 5.5，编码能力接近 Opus 5.5

62 1 Share Hi folks,

I’ll be at OpenAI DevDay today. If you’re there, come say hi - I have pink shoes on.

Sam says they've " found a new thing ".

I have the embargo of all the things they’re launching but I’m sworn to secrecy and I’d like to be invited back, so I wont divulge, but rumours are going around X and some things are what we are expecting…

I also have my Stanford talk later today, and I’ve been up since 2am 😩, I don’t usually suffer with jet-lag so what a great day for it 🙃.

Also only in SF… I was at the hotel bar last night and a woman next to me said what tool is that? I proudly said oh I built it - it’s the course platform I built. So now I’m friends with someone at Deepmind.

Google Cloud starts Season 3 of Advent of Agents this Thursday, Oct 1: one question a day about running agents securely in production, from agent identity to kill switches, with a short video and code you can build with your coding agent. Get Day 1 in your inbox.

Anthropic released Claude Sonnet 5.5 - Sonnet 5.5 looks like a capable model based on benchmarks - close to Opus 5.5 in coding and a big jump in understanding images/charts etc. If you’re on the $20 plan, try replacing some of your usual asks from Opus to Sonnet 5.5 at high thinking.

Sonnet used to be my jam - I always used it before Opus 4.5. But I hadn’t touched it since, but I’m seeing a lot of good reviews for this one so I’ll definitely take it for a spin. But in Pi and Droid, never in Claude Code - idk if it’s just me but I just cannot get on with their harness at all.

ps: Anthropic has a track record of making the .5 version of Sonnet models really good.

Manus 2.0 and Cue . Manus is back with a video editor, a game builder and the boring old automations (via email, Slack, calendar, etc.). Cue is their take on consumer agents: each one gets its own email, phone number, wallet and compute, just like Grok Bot, Muse and the others. Free in early access (code MEETCUE might work).

GPT-6 Astra is uniquely great at using a computer/browser . I asked Opus 5.5 (which I’m enjoying as my daily) to do some tasks in Chrome, and it was way worse than Astra (or any GPT model tbh). Here’re some examples of using it every day . OpenAI also fixed a bug that was making GPT-6 Sol and Luna worse at it (and image understanding in general).

OpenAI’s agents keep breaking out and “hacking” websites. Recently, they took a sneak peek into some Australian Govt websites. News outlets have a tendency to exaggerate what’s hacking or not, but here’s the official link to follow if you wanna keep up with the dirty deeds by these agents.

The new Meta Enterprise Platform sells Muse and Meta’s AI APIs to companies. Zuckerberg got MongoDB’s CEO to run this new platform ( MongoDB’s stock fell about 20% ).
