Adds native support for AWS Bedrock's Mantle endpoint (`bedrock-mantle`), which serves models with no `Converse`/`Invoke` support on `bedrock-runtime`, such as GPT-5.5, GPT-5.4, and Grok 4.3 but more importantly **open-weight** models Closes #60471 ## What's changed - Renamed the existing `Model` enum in the `bedrock` crate to `ConverseModel`, and added a new `MantleModel` enum for Mantle-only models. Mantle models reuse the existing OpenAI-compatible Chat Completions/Responses request and response plumbing (`into_open_ai`/`into_open_ai_response`, `OpenAiEventMapper`/`OpenAiResponseEventMapper`) already used by the native OpenAI and OpenAI-compatible providers, rather than introducing new marshalling code. - Added a `BedrockMantleModel` language model that routes requests to the `bedrock-mantle` endpoint, dispatching to Chat Completions or the Responses API depending on the model. Mantle models appear in the model picker alongside Converse models under the same Bedrock provider. - Added region gating: `bedrock-mantle` is only available in a subset of AWS Regions, so using a Mantle model outside of them surfaces a clear error naming the current Region and the supported ones, instead of an opaque HTTP failure. - Implemented Bedrock bearer token authentication for Mantle requests: a configured Bedrock API key is used as-is, and every other auth method (IAM credentials, named profile, SSO, automatic) derives a short-term token by locally SigV4-presigning a `CallWithBearerToken` request. This requires no extra network round trip and no token caching, since re-signing locally is cheap. - Added a specific error for the 403 you get when your credentials have `bedrock:CallWithBearerToken` but not the separate `bedrock-mantle:CallWithBearerToken` permission Mantle models require, since this is the most common misconfiguration. - Added a `mantle_available_models` setting so custom models served through `bedrock-mantle` can be configured, the same way other providers support custom models via `available_models`. - Documented Mantle models and the new setting in the Amazon Bedrock section of [Use a Gateway](https://zed.dev/docs/ai/use-a-gateway#amazon-bedrock). ## Testing - Added unit tests covering: the local SigV4 bearer-token signing (including a byte-for-byte cross-check against a reference implementation), Mantle endpoint URL construction, the Mantle-supported-regions list, thinking-effort normalization, and the settings-to-model protocol mapping. - `cargo test -p bedrock -p language_models -p settings_content -p settings` passes. - `./script/clippy` passes with no new warnings. Release Notes: - Added native support for AWS Bedrock's Mantle endpoint, enabling GPT-5.5, GPT-5.4, and Grok 4.3 through the Amazon Bedrock provider. |
