We're extending Claude Fable 5 access on all paid plans, as well as keeping Claude Code’s weekly rate limits 50% higher, through July 19.

Today we share the worldview behind our mission.

Human values don't average out. Local knowledge can't be centralized. The good future has many AIs, raised in different places, shaped by the people they serve, disagreeing with each other the way we do.

We started 8090 a few years ago on the belief this motion would become widespread. We’ve been surprised by how fast it has taken hold. That said, it’s still so early in this game.

Software license revenue is $1T annually. Services and T&M consulting around those licenses is $4T annually.

All of this will merge into a new $5T super-category and whatever happens from there is anyone’s guess. But I applaud $SBUX for ripping off the bandaid - they clearly see the forest from the trees.

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 and debugging will fall back to Opus 4.8. We’ll continue to refine these classifiers over the coming weeks to reduce false positives and better distinguish genuine misuse from legitimate requests.

We’ve also begun drafting a consensus framework—with Amazon, Microsoft, Google, and other Glasswing partners—for assessing the severity of AI jailbreaks and how AI developers should respond to them. We invite other industry partners and model providers to join us in this effort.

Finally, we’re scaling up our collaboration with the US government on model testing and safeguards. This will include pre-release access to models and safeguards for evaluation, information sharing on jailbreaks and misuse, and dedicated resources for joint research.

Thank you to our users for your patience, and to our partners across the government, industry, and the research community who worked alongside us to make Fable 5 available again.

This also means Chinese models are almost certainly going to be restricted in some way - possibly even banned - in the West. Right now they're roughly nine months behind. If every American frontier release is forced into a slow, staggered rollout from now on, they'll start closing that gap immediately. Over time, this destroys Western labs business models, because users will eventually have access to genuinely equivalent open-source alternatives - and in time, even better ones! The US government will not allow that to happen. The only way to prevent it is if China agrees to the same staggered release schedule (unlikely but I suppose it's possible), keeping the gap roughly where it is today. Otherwise, the US will likely restrict or ban Chinese models. There's probably a nine-month window, at most, probably a lot less, before one of those outcomes plays out.

[Anthropic @AnthropicAI]

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.

The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.

Access to all other Claude models is not affected.

We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use.

Its capabilities exceed those of any model we’ve ever made generally available.

Leading companies are moving from two-week sprint cycles to a daily rhythm that combines human judgment with overnight agent execution.

The opportunity now is how organizations use the capacity those agent-enabled workflows create. https://t.co/heERvijLRD

Introducing Claude Opus 4.8: it builds on Opus 4.7 with sharper judgment, more honesty about its own progress, and the ability to work independently for longer than its predecessors.

Available today at the same price.

Our master plan is to release better and more efficient models. And also to release better products, week after week. Oh and get more compute too. Together with spending too much time on x. How good is this plan?

Bragging about how much software you’re shipping with AI is like holding down the shutter button and bragging about how many photos you took.

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.
