- Updated `ApplyPayloadConfigWithRoot` to prioritize `disable-image-generation` filtering before applying payload rules.
- Ensured payload overrides can explicitly re-enable `image_generation` when required.
- Added unit tests to validate `image_generation` restoration through overrides.
- Introduced `DisableImageGenerationMode` with support for `false`, `true`, and `chat` values.
- Updated payload handling to preserve `image_generation` on images endpoints when `chat` mode is enabled.
- Modified OpenAI image handlers (`ImagesGenerations`, `ImagesEdits`) to respect tri-state logic.
- Added unit tests for `DisableImageGenerationMode` behavior and endpoint-specific handling.
- Enhanced configuration diff logging to support `DisableImageGenerationMode`.
- Added logic to remove `tool_choice` entries of type `image_generation` from payloads when `disable-image-generation` is enabled.
- Updated `ApplyPayloadConfigWithRoot` to handle new removal logic.
- Added unit tests to verify `tool_choice` removal behavior.
- Added `disable-image-generation` configuration flag to disable the `image_generation` tool globally.
- Updated payload handling to remove `image_generation` tools from request payload arrays when the flag is enabled.
- Modified OpenAI image handlers (`ImagesGenerations`, `ImagesEdits`) to return 404 when the feature is disabled.
- Enhanced configuration diff logging to track changes for the `disable-image-generation` flag.
- Added accompanying unit tests for the new feature in payload helpers and image handler logic.
- Introduced tests to ensure unsupported models are rejected in `/images/generations` and `/images/edits`.
- Added `isSupportedImagesModel` and `rejectUnsupportedImagesModel` functions for consistent model validation.
- Enhanced image handler logic to apply validation checks for model compatibility.
The loadCodeAssist polling call hardcoded the User-Agent to
google-api-nodejs-client/9.15.1. Google Cloud Code returns the
paidTier object WITHOUT the availableCredits array for that UA,
so updateAntigravityCreditsBalance always saw "no credits", set the
hint to Available=false for every Google One AI Ultra account, and
the conductor-level credits fallback could never find a candidate.
Switching to resolveUserAgent(auth) (the same UA used for
streamGenerateContent / generateContent) makes the response include
availableCredits, so the credits hint is populated correctly and the
fallback can actually inject enabledCreditTypes:["GOOGLE_ONE_AI"]
when free tier is exhausted.
- Implemented `appendReasoningContent` to support processing of `thinking` signature and text as reasoning input.
- Added test cases to validate reasoning content conversion with and without text.
- Added `buildAdditionalModelRecord` to filter out zero-token usage details.
- Introduced `hasNonZeroTokenUsage` helper function for token usage validation.
- Updated tests to cover scenarios for zero and non-zero token usage.
- Introduced a `Disabled` flag to OpenAI compatibility configurations.
- Updated routing, auth selection, and API handling logic to respect the `Disabled` state.
- Extended relevant APIs, YAML configurations, and data structures to include the `Disabled` field.
- Adjusted all relevant loops and filters to skip disabled providers.
Closes: #3060#3059#2977
GPT-5.5 was correctly removed from codex-free tier in 7b89583c
(since free accounts cannot access it), but the test was not updated
to reflect this. This caused TestCodexStaticModelsIncludeGPT55 to
fail on the free subtest.
Changes:
- Remove free tier from GPT-5.5 inclusion test
- Add new TestCodexFreeModelsExcludeGPT55 to explicitly verify
that free tier does NOT include GPT-5.5
- Updated `buildImagesResponsesRequest` to derive `model` dynamically based on `toolJSON`.
- Adjusted streaming execution to handle dynamic model resolution across multiple contexts.
Closes: #2965
- Added IP ban logic to `AuthenticateManagementKey` and Redis protocol handlers, blocking requests after multiple failed attempts.
- Introduced unit tests to validate IP ban behavior across localhost and remote clients.
- Synchronized Redis protocol's authentication policy with management key validation.
- Added `protocol_multiplexer.go`, enabling support for both HTTP and Redis protocols on a single listener.
- Introduced `redis_queue_protocol.go` to handle Redis-compatible RESP commands for queue management.
- Integrated `redisqueue` package, supporting in-memory queuing with expiration pruning.
- Updated server initialization to manage a shared listener and multiplex connections.
- Adjusted `Handler` to adopt `AuthenticateManagementKey` for modular key validation, supporting both HTTP and Redis flows.
