Claude Fable 5 Free Access Ends Today - Subscribers Got About Half the Window Advertised

Fable 5 billing starts today. Anthropic promised 13 days of Claude Fable 5 free access to Pro, Max, Team, and Enterprise subscribers - but a US government export-control directive grounded the model from June 12 to June 18, cutting the usable window to about seven days. Starting June 23, any Fable 5 session draws from prepaid usage credits at $10 per million input tokens and $50 per million output tokens.

Six Days of the Free Window Were Lost to a Government Directive

Fable 5 launched June 9 alongside the larger Mythos 5, and Anthropic promised both models free to subscription users through June 22. Three days after launch, on June 12, the Commerce Department issued a national-security export-control order requiring Anthropic to cut off access for all foreign nationals. With no way to verify nationality at the API layer in real time, Anthropic suspended both models globally. Both went dark.

Around June 18, Anthropic restored Fable 5. By day nine of the outage, the company had offered no restoration timeline and no extension of the free window. When Fable 5 came back, developers noticed it falls back to Claude Opus 4.8 more often than the original launch version - particularly on prompts involving cybersecurity, chemistry, and biology. Anthropic has not explained why.

Billing Starts Today at $10 per Million Tokens

Anthropic always framed Claude Fable 5 free access as temporary. Today it ends. Starting June 23, Fable 5 keeps working on all subscription plans - but sessions now draw from prepaid usage credits rather than plan limits. Anthropic called the temporary inclusion a capacity decision: building infrastructure to serve Fable 5 within flat subscription pricing takes time, and the company has committed to restoring it as a standard plan feature once that capacity exists.

Input tokens cost $10 per million. Output tokens cost $50 per million - roughly double what Anthropic's previous flagship, Claude Opus 4.8, runs at API rates. Teams who built workflows on Fable 5 during the free window need to budget for that gap now.

Anthropic committed to restoring Fable 5 to plan limits once capacity allows. No date. Anthropic has announced no credit or extension for the six disrupted days. Offering no refund while starting the usage-credit meter is a decision subscribers will be watching closely.

Mythos 5 Remains Off Limits for Most Users

Mythos 5 has not returned. Anthropic restricted access to Project Glasswing partners on June 12 and has set no public restoration timeline. For most teams, the model Anthropic announced alongside Fable 5 was unavailable for the entire free window - so the 13-day subscription offer never applied to it in practice. Anthropic has not disclosed whether Mythos 5 will receive its own free access window when it eventually returns to general availability.

Prediction markets this week put the odds of a full Fable 5 restoration to plan limits - returning to standard subscription access, not usage credits - before August 2026 at 57%. Anthropic has not commented.
