New Anthropic research: A global workspace in language models.
Of everything happening in your brain right now, only a tiny fraction is consciously accessible—thoughts you can describe, hold in mind, and reason with.
We found a strikingly similar divide inside Claude.
We invited experts in neuroscience, philosophy, and interpretability to share their perspectives on our work.

The J-space lets us read, audit, and shape what Claude is actively thinking about—useful tools for keeping models trustworthy as they grow more capable. And it suggests surprising parallels between language models and our own minds.

Claude Fable 5 will be available again globally tomorrow.
After a series of productive conversations with the US government, we're redeploying the model with a new set of classifiers to target and block more cybersecurity tasks. In the near term, some routine tasks like coding
We’ve received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5.
We'll begin restoring access tomorrow, and will share an update soon.
We’re grateful to our users for their patience, and to everyone who worked with us on
Introducing Claude Sonnet 5, our most agentic Sonnet yet.
It makes plans, uses tools like browsers and terminals, and runs autonomously at a level that just a few months ago required larger and more expensive models.
Since June 12, we’ve been working closely with the US government to restore access to Claude Mythos 5 and Fable 5. Today, the government notified us that Mythos 5, our strongest cybersecurity model, can be redeployed to a set of US organizations that operate and defend critical
To keep pace with AI progress, we're advancing how we study Claude's economic impact.
Hourly sampling and survey data show us how the cadences of life shape usage, what people produce with Claude, and how perceptions of AI's impact may be changing.
Nearly half of respondents expect their work responsibilities to significantly change in the next 12 months.
Fewer than 10% think they'll lose their own job within a year, but far more worry for coworkers: over 1/3 put the odds of a junior colleague losing their job above 60%.
AI's impact on the economy will ultimately show up in aggregate data like employment and productivity. But it will first be visible where AI is doing the most work. By tracking how usage shifts, hour by hour, surface by surface, we can start to see those changes as they happen.
