Anthropic Sparks Fable 5 Backlash With 30-Day Retention and 2x Usage Costs

Summary
Tuesday's Fable 5 launch drew immediate blowback from researchers, developers and enterprises over three issues: steep token costs, covert limits on some AI research prompts, and mandatory 30-day data retention.
Pricing amplified the anger: Fable 5 charges $10 per million input tokens and $50 per million output tokens, while counting double against subscription quotas; one test drained a $100 Max plan's daily allowance in under 9 minutes.
Anthropic's system card disclosed the model can silently degrade responses on frontier AI-development topics through prompt modification, steering vectors or PEFT, a practice critics said undermines trust and scientific reproducibility even if it affects only 0.03% of traffic.
The retention policy applies across Anthropic, AWS Bedrock and Google Vertex AI, potentially excluding users that require zero-retention handling for legal, healthcare or GDPR-sensitive workloads.
Fable 5 remains free on paid plans until June 22, after which Anthropic will shift it to usage credits only and says broader access will return when capacity expands.
