That's my designer - Claude

and it comes with a new model, Opus 4.7

Apr 21, 2026

Hey folks,

I’ve been playing a lot with Claude Cowork for my talk at Stanford later today. It’s comically bad for the average jane.

A lot of capabilities are enabled using connectors and plugins, but if you don’t know that, good luck getting it to do anything. Can’t seem to send emails, install a skill or tell me about what potential connectors are there.

Scheduled tasks in Cowork stop when you shut the lid, but Routines (similar thing) in Claude Code do not. Cowork is just now getting Artifacts - the mini apps on the Claude chat app that started the vibe-coding wave.

I can search for all of this, yes. but an average user will not. and they’ll walk away thinking AI is hype for the next 6 months/a year.

Anyway, the Cerebral Valley AI Summit is coming back to London on June 24th. I’m planning to be there.

Headlines

Opus 4.7 is out - much better at vision (interpreting images) and efficient at using reasoning tokens. A new xhigh level of thinking now sits between “high” and “max”. I’ve been using it over the weekend at xhigh and didn’t face any issues (despite the general sentiment on Twitter that 4.7 is a regression).
Claude also has a Design tab now - a canvas-like interface with chat on the sidebar to explore wireframes or create high fidelity prototypes. It asks you 5-10 questions via an interactive form and then gets building. I found the image → design workflow to be really good in the prototype mode. Has separate limits while in research preview, but expect the weekly limits to only last for 2-3 big generations max (on the $20 plan). Check out Peter’s demo across multiple use cases.
Codex got a few updates: 1. Computer Use - it can now use apps on your Mac. I’m not completely sold on it and have some questions, but it does seem to work a lot faster than previous iterations of computer/browser use demos. Also, it works in the background, so your Mac is free for you to use. 2. Chronicle, an opt-in preview that uses recent screen context to build memories. 3. A bunch of plugins, including image generation, so that Codex can be the superapp to use AI.
Factory AI is now valued at $1.5B after their latest raise of $150M. Try the new desktop app for Droid, Factory’s coding agent, with 50% off on Opus 4.7 till 30th April.
