Fable 5 Is Back — With Strings Attached
- @AnthropicAI Announced Fable 5's return after US government talks and new cybersecurity classifiers.
@claudeai Confirmed Fable 5 is officially back live.
@theo Reported the 50% usage limit cap on Fable 5 through July 7 and shift to usage credits.
@alexstamos Provided critical analysis noting Anthropic confirmed jailbreaks offered no capability beyond existing Chinese models.
@danshipper Expressed concern that the new Fable guardrails will be more restrictive on innocuous requests.
Anthropic redeployed Claude Fable 5 globally after "productive conversations with the US government," adding new classifiers to block more cybersecurity tasks — with some routine coding tasks caught in the crossfire. The model officially went live again Tuesday evening. Access won't be unlimited: Fable 5 will cover up to 50% of weekly usage limits through July 7, then shift to usage credits. Security analyst Alex Stamos cut through the PR: Anthropic quietly confirmed that none of the jailbreaks that triggered the pullback gave attackers capabilities beyond what Chinese models already offer. There's already skepticism about the revamped guardrails — some worry "Fable: Lutnick's Version" will be noticeably more restrictive on innocuous requests.
