Anthropic's Fable 5 model returned to user access on Wednesday after the Trump administration lifted an export control late Tuesday.
Why it matters
Fable 5 is among the most powerful AI tools publicly available, and U.S. officials required Anthropic to implement additional safety measures before allowing broad access because of security and safety concerns.
How access will work
Anthropic said Fable is available to all customers, but queries the company judges to pose security or safety risks may be routed to less powerful models. For most customers, using Fable will occur outside standard subscription plans and will be billed per token consumed.
Anthropic also stated that subscribers may use Fable for up to half of their included data usage until July 7, while cautioning that Fable consumes tokens faster than other models.
Bigger picture
The temporary block and subsequent release of Fable has raised questions about when and how the Trump administration will step in to limit future releases of frontier models. In a related development, OpenAI has said it is withholding a broad release of its latest model, GPT 5.6, while it consults with the government, which requested the delay.
Implications
The episode underscores the growing role of government intervention in regulating access to advanced AI systems and suggests providers may need to combine technical safety controls with commercial restrictions to address regulator concerns.
