Anthropic has extended access to Claude Fable 5 on all paid plans until 19 July. The company announced this change alongside a decision to maintain weekly rate limits for Claude Code at 50 percent higher than standard. Users can now spend up to half their weekly usage allowance on the model before switching to other options or using credits. This adjustment follows the initial release of GPT-5.6 Sol, which Anthropic classifies as a Fable or Mythos level model. The original plan was to restrict availability due to compute constraints and uncertainty about demand. OpenAI appears confident enough to avoid similar restrictions on its new model. The delay in committing to permanent access for Fable 5 highlights a strategic hesitation regarding resource allocation.
While the extension provides temporary stability, it does not resolve the underlying issue of inconsistent availability. OpenAI is gaining users partly because its new capabilities remain accessible without interruption. Anthropic might consider making Fable 5 permanently available on paid subscriptions to match this approach. Uncertainty about model access can drive customers toward competitors who offer clearer terms. Keeping such advanced models restricted prevents long-term planning for enterprise clients.
- Access extends to July 19 across all paid tiers
- Claude Code weekly limits remain 50 percent above standard
- OpenAI avoids similar usage restrictions on GPT-5.6 Sol
