Anthropic Ends Fable 5 Free Period, Shifts Model to Paid Credits

Anthropic is ending, on July 7, 2026, the period during which Claude subscribers could use the Fable 5 model at no extra cost. Starting July 8, access to the model for users on Pro, Max, and Team plans shifts to a separately purchased credit system billed at rates close to API pricing, $10 per million input tokens and $50 per million output tokens.

Fable 5 is one of the models in the Claude 5 family, and it has had a turbulent availability history in recent weeks. It was originally meant to be available for two weeks, until June 23, but on June 12 Anthropic pulled it after Amazon reported a security flaw that allowed users to bypass the model's safety guardrails. It returned on July 1, but in a reduced form: instead of the original two weeks of full access, subscribers got one week at just half the standard limit.

A new safety classifier

Alongside the model's return, Anthropic rolled out an updated automated safety classifier designed to block exactly the kind of guardrail bypass Amazon had described in its report. The company acknowledged, however, that the new mechanism may incorrectly flag some harmless requests, particularly during routine coding and debugging, and said it would work to reduce the number of such false positives in the coming weeks.

Subscriber backlash

The decision has frustrated paying users who expected the full two weeks of access promised in the original announcement. Complaints about the shortened window and reduced limit have surfaced on Reddit, with some subscribers noting that in practice they got only a few days of real access to the model out of the fourteen originally promised.

Bringing Fable back and then cutting the limit and the number of access days at the same time is not a good solution - a Reddit user

What happens to access now

The change affects different plans differently. Pro, Max, and Team subscribers, who had an allowance of up to half their weekly limit through July 7, must from July 8 activate and cap credits manually in the usage settings on claude.ai. Standard Enterprise accounts had no built-in allowance either and must also turn on credits separately, while Enterprise Premium accounts keep access included in their subscription, billed against each user's assigned limit at no extra charge.

Anthropic has not yet published a conversion that ties the concept of "50 percent of the weekly limit" to a concrete number of tokens, messages, or dollar amount for each plan, nor a clear exchange rate from credits to dollars under the new system. That lack of transparency makes it hard for users to estimate what they will actually pay to keep using the model.

The company has said it intends to restore Fable 5 as a standard subscription feature once available computing capacity allows, attributing the current restrictions to very high and hard-to-predict demand for the model. At the same time, Anthropic restored access to the related Mythos 5 model for organizations in the United States after obtaining government approval, with plans to expand to international partners under the Glasswing program.

For Polish companies and developers using Claude, this means actively monitoring credit usage if they want to keep using Fable 5 after July 7, and factoring in an additional AI tooling cost that was not previously part of the standard subscription.
