Cowork is now in the M365 Frontier Program

Recently, Microsoft also announced that it would bring Anthropic’s Claude Cowork tool — essentially Claude Code for knowledge workers who need long-running agents who can complete multi-step workflows — to Copilot.

Imaginatively named Copilot Cowork, this feature is now available in the early-access Microsoft 365 Frontier program.

TL;DR

1. A misconfigured CMS exposed ~3,000 internal Anthropic assets, revealing the existence of Claude Mythos (Capybara tier), described as a “step change” over Opus 4.6. (Fortune, 03/26)

2. Mythos is “far ahead of any other AI model in cyber capabilities.”Cybersecurity stocks dropped 4.5% to 9% in a single session. (CNBC, 03/27)

3. The RSP v3.0, which removed Anthropic’s pause commitment, had been published 30 days before the leak. (Anthropic RSP v3.0)

4. ASL-4, the safety level that should cover a model of this power, has not been defined yet.

5. Anthropic is targeting an IPO at $60B+ in Q4 2026. The timing of the leak, accidental or not, amounts to free worldwide marketing. (The Tech Portal, 03/27)

• A leaked draft blog post revealed that Anthropic is testing a new AI model, Claude Mythos, which it internally describes as by far its most powerful system to date.

• The model, part of a new "Capybara" tier, reportedly delivers dramatically better performance than Claude Opus 4.6 on coding, academic reasoning and cybersecurity tasks, raising concerns about unprecedented cyber risks.

• The incident underscores both the dual-use danger of advanced AI in areas like DeFi security and the irony that a company touting cutting-edge cybersecurity capabilities exposed details of its own model through a basic content management error.

I'm sure you've seen the little Claude logo pop up in your favourite open source repo's contributor list by now. I know I have. In fact, I've been seeing it pop up everywhere, it seems.

Just how everywhere is it?

That is the reason for this project. I wanted to find out, so I started looking for commits by the Claude bot itself, meaning contributions made by the Claude Code GitHub Action. At this point I half expected there to be many millions of commits across thousands of repositories by the Claude bot.

There were a few thousand (8000 to be precise) when I started.

Disappointing
