Anthropic, the AI research company, announced on July 20, 2026, that it will integrate its advanced Fable 5 model into the Max and Team Premium subscription plans, offering it at 50% of weekly usage limits.

This move follows a phased rollout since July 1, where Fable 5 was initially available to Pro, Max, Team, and select Enterprise plans with limited usage.The decision comes after addressing capacity constraints and user demand, which had been unpredictable.Pro and Team Standard users will still access Fable 5 via usage credits, receiving a one-time $100 credit.Usage credits allow continued access beyond included limits for paid Pro, Max 5x, and Max 20x subscribers.

Anthropic emphasized that Fable 5, a public version of the Mythos AI model, is its most powerful tool for widespread use, excelling in software engineering, research, and complex tasks.The model was temporarily restricted in June 2026 due to U.S.government concerns over national security, but has since been reinstated.The company aims to provide clearer plan details to users, ensuring transparency about access and capacity expansions.
