Claims
- Anthropic extended Claude Fable 5 access on all paid plans and kept Claude Code weekly rate limits 50% higher through July 19.
- The extension was triggered by GPT-5.6 Sol being considered a Fable/Mythos class competitor, making access continuity a competitive issue.
- OpenAI removed the five-hour usage limit for Plus, Business, and Pro plans and is rolling out efficiency improvements to GPT-5.6 Sol.
- OpenAI reached 6 million active users on its latest model release.
- Simon Willison argues Anthropic is losing users to OpenAI due to ongoing uncertainty around Fable availability on paid plans.
Key quotes
We're extending Claude Fable 5 access on all paid plans, as well as keeping Claude Code's weekly rate limits 50% higher, through July 19.
At this point I think Anthropic should change track and keep Fable permanently available on those plans. OpenAI are winning users simply due to the uncertainty that surrounds Fable access.
Temporarily removing the 5 hour usage limit restriction for all Plus, Business and Pro plans
