# Fable gets another bump > Source: > Published: 2026-07-12 21:20:07+00:00 One of the consequences of GPT-5.6 Sol being clearly a Fable/Mythos class model is that Anthropic have, once again, [bumped the date](https://x.com/claudeai/status/2076351399999557669) that Fable stops being available in their Claude Max plans: 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. As before, you can use up to half of your weekly usage limit on Fable 5. After that, you can continue using Fable 5 with usage credits, or switch to another model to keep working within your remaining limits. Anthropic's original rationale for this was compute constraints - they wanted a better idea of both demand and compute availability before committing to keeping the new model cheap for subscribers. OpenAI appear confident that they won't need to restrict access to GPT-5.6 in the same way. 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.
