Claude’s Constitution is now an audiobook, read by two of its authors, Amanda Askell and Joe Carlsmith. It includes a Q&A on the writing process, the philosophies that shaped the document, and how it might change as models become more capable. Listen at

So Mythos was, indeed, not marketing hype. Remember this is a general purpose model that just happens to be good at finding exploits because good models are good at lots of things. Expect similar from OpenAI & Google. And from open models in 8 months.

The UK’s state AI Security iIstitute findings: 1) Mythos is a big gain in cyber capabilities. But so is GPT-5.5 2) It is hard to establish an upper bound on Mythos/GPT-5.5, which appear to be limited by tokens used, rather than ability. 3) Capability doubling time is 4.5 months

A lot of people have been wondering about Mythos, Glasswing, and the vulns we / our partners are fixing. Today, I’m excited for us to start sharing more. (For context, I lead Glasswing @AnthropicAI.) Two independent evaluations this week–from XBOW and the UK AISI–confirm what

Apple may be planning to role out its updated Siri based on 2024’s vision at the moment when Claude Code and Codex (also OpenClaw) can increasingly do the actual assistant thing: read my emails & calendar, proactively spot & solve problems, do delegated tasks, work with voice etc

The new version completely smashes GPT-5.5 and the previous Mythos version. Before Mythos Preview completed the cyber range 3 out of 10 times. The new version completed it 6 out of 10 times and is much more efficient!

According to the new data from Ramp, Anthropic has passed OpenAI in business adoption for the first time. ‘Adoption of Anthropic rose 3.8% in April to 34.4% of businesses. OpenAl adoption fell 2.9% to 32.3%. Overall Al adoption rose 0.2 percentage points to 50.6%.’

OpenAI for Excel is quite useful (as is Claude for Excel), so it is surprising, that, unlike Claude, there is no OpenAI for PowerPoint, especially because it is where OpenAI has a big advantage: Imagegen-2 can make very good slides/images directly, where Claude has no image maker

“She said the theme of this party is the industrial age. And you came in dressed like a train wreck.” Asking AIs to think of the equivalent to this Hold Steady lyric, but for AI. Claude was the clear winner: “”…And you came in dressed like slop.””

I don’t understand the path forward for Mythos releases. Google & OpenAI will have equivalent models, and they are approaching AI cyber risk guardrails differently, so they will presumably just release their versions. How does Anthropic get out of the government approval path?

Anthropic just freed up a bunch of compute by blocking open source devs and apps from using Claude Code 🙃

Apparently an unpopular opinion, but I don’t think Anthropic owes anyone heavily subsidized tokens for their third party app.

I can’t help but feel personally burned by the Claude Code changes announced today. We put so much work into wrapping the (atrocious) Claude Agent SDK in T3 Code. It was the ONLY path they supported, so we made it work. It was hell. Now our users are getting their rate limits

If you use any of the following with your Claude sub, your usage must got cut by 25x: – T3 Code – Conductor – zed – jean – “Claude -p” in your ci – scripts to call Claude code from other tools They’re disguising this as “free credits”. Don’t fall for it.

Starting June 15, paid Claude plans can claim a dedicated monthly credit for programmatic usage. The credit covers usage of: – Claude Agent SDK – claude -p – Claude Code GitHub Actions – Third-party apps built on the Agent SDK
https://x.com/ClaudeDevs/status/2054610152817619388
The comment section tells you everything. I mostly use Claude Agent SDK (~80%) and sometimes Claude Code interactively (~20%). I prefer my own harness/UI over Claude Code CLI/Cowork. Most of my use cases with agents involve programmatic use (e.g., long-running loops and
https://x.com/omarsar0/status/2054679776397300188
This is misleading. This policy redefines the term “”interactive”” to mean “”using an Anthropic front-end””. If you use `claude -p` or Agent SDK to do something interactively, it now uses credits, not your subscription limits. So the “”interactive use”” heading saying “”unchanged””

I realize that “Mythos as hype” means two different things to different groups. For insiders, it means “Mythos was not a magical step-change in AI ability.” For outsiders, it means “Mythos couldn’t really find zero day exploits” The latter was wrong, the former was likely right

The personification of Claude — in name (the only AI with a human one), in training, in Anthropic’s philosophy (see Claude Constitution), in fanfiction (see the Claude cartoons), etc — feels quite consequential in the medium term, for better and for worse.

Anthropic: “Claude Mythos is too cyber-capable to release broadly. We need tight controls. 😳” OpenAI: “Here’s GPT-5.5-Cyber, Codex Security, Trusted Access tiers, repo scanning, patch generation, and red-team workflows. Please be verified first, but yes, go find the bugs. 😎”

It is remarkable how quickly this market shook out. Anthropic & OpenAI are in business take-off, at least: they have the model development, enterprise deals, compute deals, government & press attention and consumer recognition. Only potential competition is Google (& maybe Meta)
https://x.com/emollick/status/2052416783538135421
Enterprises are going to actually want a coherent roadmap for the development of tools like Codex and Cowork, so they can plan and train and scale their use. This conflicts with the Labs’ vision where these tools rapidly scale exponentially in ability as models approach AGI.

Unpopular opinion: as a heavy user of claude -p on Claude Max plans, I actually think Anthropic is going to come out ahead with this move. If Anthropic had to turn flat fees off for programmatic usage, OpenAI is going to have to eventually as well. Anyone relying on these flat
