July 7, 2026, (Inside AI) — Anthropic has extended complimentary access to its most powerful general-purpose AI model, Claude Fable 5, for all paid subscribers through July 12, 2026. The extension, announced via the official Claude X account, applies automatically to all Pro, Max, Team, and select Enterprise plans.
The 5-day extension comes just days after the model was restored to global availability on July 1. That restoration followed a 19-day suspension triggered by U.S. government export controls, which were enacted after Amazon researchers discovered a jailbreak that could bypass the model's safeguards.
Under the extended terms, subscribers can continue to allocate up to 50% of their weekly usage allowance to Fable 5. Requests that trip the model's safety classifiers are automatically rerouted to the less capable Claude Opus 4.8, a mitigation strategy Anthropic has termed a "fallback."
This represents a second temporary reprieve. Access was originally slated to end on July 7, with paid plans transitioning to a usage-credit model for continued Fable 5 access after that date. The latest extension pushes that transition to July 12 at 11:59 PM PT.
Anthropic's announcement noted that the 50% weekly cap remains in effect. The company has not indicated whether Fable 5 will become a permanent standard feature of subscriptions once the extension expires. Company engineers previously stated that Anthropic aims to integrate Fable 5 into standard subscriptions "as soon as capacity permits."
Anthropic launched Fable 5 on June 9, describing it as the company's first "Mythos-class" model made generally available, a model that represents a significant advancement in capability for complex, multi-step tasks. The model is also available via the Claude API, Amazon Bedrock, Google Cloud, and Microsoft Foundry at a price of $10 per million input tokens and $50 per million output tokens.
The extension on access to Fable 5 occurs as competitors accelerate their own frontier model releases. OpenAI recently announced its GPT-5.6 series, a release that some analysts predict could see a user shift should access to Fable 5 be curtailed.
