The gist: Anthropic will continue offering Claude Fable 5 until July 19 across all paid Claude Max plans and maintains higher usage limits for Claude Code.
Anthropic has once again extended the availability of Claude Fable 5 for paid plans. The reason is the classification of GPT-5.6 Sol as a Fable/Myth model, which puts pressure on resource allocation at Anthropic.
Anthropic has extended the availability window for Claude Fable 5 once again. The model will remain available on all paid plans until July 19, 2026. Users can use up to half of their weekly quota for Fable 5; beyond that, they can either spend credits or switch to other models. At the same time, weekly usage limits for Claude Code are being increased by 50 percent, also until July 19.
The background to this decision is compute constraints. Anthropic has so far deliberately created uncertainty around the permanent availability of Fable to gather better data on demand and available compute capacity. In contrast, OpenAI is signaling confidence that GPT-5.6 can be deployed without access restrictions.
These repeated shifts in availability deadlines raise questions about long-term strategy. OpenAI wins users through the predictability of its model availability, while uncertainty around Fable access creates frustration among existing users and drives new users to competitors.
