A day after the commerce blueprint, Anthropic follows up with a 25-minute guide. The main lessons: one agent with skills beats a subagent architecture, every UI element is a tool, and no model ever gets to move money on its own.
US Commerce Secretary Howard Lutnick says Anthropic is 'back on the right side.' After export controls, a Pentagon blacklist and a court fight, that is quite a turnaround. And co-founder Tom Brown is suddenly the one in the spotlight.
Astra uses a technique called 'recurrent depth': the model runs a query through itself several times instead of writing out its reasoning step by step. That makes the chain of thought harder to read. Redwood Research and Zvi Mowshowitz warn of a race to the bottom.
Anthropic is locking in compute at scale – a $35 billion cloud deal with Nvidia-backed Lambda, tied to a data center campus in Texas. Just ahead of a planned IPO, it says more about strategy than about hardware.
On Fable 5.1's launch day, Claude Code follows right along: 2.1.257 makes the new model the default, finally brings configurable time formats and a new auto-mode rule. 2.1.258 clears up a nasty startup failure on macOS Monterey.
Anthropic shipped Fable 5.1 and Mythos 5.1 – the same model with different levels of safeguards. Two things stand out: the price drops by around 25 percent, and the real-world research examples are surprisingly concrete.
Since Fable 5, Anthropic had to keep all traffic for 30 days. Many business customers found that unacceptable. Now there's a solution where the data stays in the customer's own cloud and no Anthropic employee ever looks at it.
Simon Willison ran all five effort levels of Fable 5.1, Nick Saraev picked apart the benchmarks. The upshot: low and medium apparently don't think at all, while max produces the best pelican Anthropic has ever drawn, at a cost of 14 minutes.
