There was a problem hiding this comment.
Structured output wrongly enabled
Medium Severity
The config lists structured_output among features, but other global.anthropic Bedrock entries with the same Converse-style setup explicitly omit that flag with a note that structured output is not supported in bedrock-converse. That mismatch can make the gateway treat the model as schema-capable when it is not.

Unsupported sampling params declared
High Severity
This Bedrock entry exposes temperature and top_p under params but omits removeParams for them. Fable 5 rejects those sampling fields (same as Opus 4.7+), while aws-bedrock/default.yaml still supplies defaults—so merged gateway requests can include them and get 400s across scenarios.

Auto-generated by model-addition-agent for
aws-bedrock/global.anthropic.claude-fable-5.Note
Low Risk
Metadata-only addition with no runtime or routing logic changes; main review risk is incorrect pricing or limits affecting billing estimates.
Overview
Adds a new AWS Bedrock provider definition for
global.anthropic.claude-fable-5so the model can be selected and costed like other Bedrock Anthropic entries.The YAML registers per-region token pricing (including prompt-cache read/create costs) across the usual global regions, marks the model active and serverless, and documents 1M context / 128K max output, thinking enabled, chat mode, and modalities text, image, and PDF in / text out. It also lists capabilities (tools, prompt caching, structured output, etc.) and default
max_tokens,temperature, andtop_pbounds, with links to AWS and Anthropic docs as sources.Reviewed by Cursor Bugbot for commit 522d92c. Bugbot is set up for automated code reviews on this repo. Configure here.
