What changed
The AWS Bedrock provider page now names Claude Haiku 5.5 in the model list, next to Claude Sonnet 5, Claude Opus 5, and Claude Opus 5.5. The page states that Claude Haiku 5.5 and Claude Opus 5.5 support prompt caching with 512-token cache checkpoints. It tells users to pick these models from the dropdown, because a manually entered model ID is an unknown model and loses prompt caching support. It also notes that Claude Haiku 5.5 runs through cross-region or global inference.
Why this change was made
Zoo Code added Claude Haiku 5.5 to its Bedrock model catalog. The docs did not mention it. A user in Discord could not find the model in the dropdown and typed the model ID by hand, which removed prompt caching and raised costs. The docs now steer users back to the dropdown.
Impact
Users who read the Bedrock provider page learn that Claude Haiku 5.5 exists, how prompt caching applies to it, and which inference option it needs. No code behavior changes in this repository.

The screenshots come from the real
ModelPickersettings component rendered with the shipped model catalog in the repository's webview gallery harness; they show rendered UI state, not a live Bedrock API call.
