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 redeploying the models.
Introducing a limited preview of GPT-5.6 Sol, our next generation frontier model, as well as GPT-5.6 Terra, a balanced model for efficient, everyday work, and GPT-5.6 Luna, a fast and affordable model for high-volume work.

my notes from the @midjourney medical launch
- @Scobleizer compared this to the original iPhone and Tesla launches (that he was also front row for)
- find you a man who looks at you like @bryan_johnson was 😍 ing for @DavidSHolz
- see @iScienceLuvr tweet linked for Nature paper
- reminds me of our @biohub episodes: better science starts with better data, and that means better imaging
- people asking "but wen FDA?" are so small minded. we will do the easy stuff, then we'll do the harder stuff. roll up your sleeves and help or just be patient.
- when you have genuinely better tech+mission, all the other hurdles just sort of fall away/figure themselves out: business model, regulatory approval, hiring, marketing, confusion over what to do
- this was just the first of 8 side project launches MJ has planned this year
- this is what technological ambition looks like: not 10% better, not 2x better, but 40-100x better in every dimension
- how are we getting this level of innovation and ambition out of a $10m/yr research budget and whats wrong with the way we use R&D in every other megacorp/goverment/frontier lab?
- how has $BFLY stock not mooned yet, this thing just had its ChatGPT moment
thank you to L for letting me into what I believe is going to be the top 10 most important launches i'll ever see live.
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.

As a result of a US government directive, we are suspending access to Claude Fable 5 for all users. You can continue to use all other Claude models.
Here’s what this means for you:
Across Claude products, new sessions will run on your selected default model or Opus 4.8, and existing Fable 5 sessions will end with an error.
On the Claude Platform, requests to Fable 5 will also return an error. Please update your integrations to other Claude models.
We know this is a disruption to your workflows; we appreciate your patience and support.
We heard you wanted to use Codex rate limit resets on your own time.
Starting today, we’re rolling out the ability to save rate limit resets to use later.
We’re starting Go, Plus, Pro, and Business users with one free reset:
Building apps has never been easier.
With Sites, Codex can turn your work, ideas, and plans into an interactive website or app your team can explore, use, and share with a URL.
Rolling out to Business and Enterprise plans, before expanding more broadly.
An early beta of Grok Build, an agentic CLI for coding, building apps, and automating workflows is now available for SuperGrok Heavy subscribers.
Through this early beta, we will improve the model and product based on your feedback.
