The spec was validated against the source code with adversarial review from multiple models, and passes Spectral linting with zero errors. Also removes openapi.yaml from .gitignore so the spec is tracked. * Mark /api/history endpoints as deprecated Address Jacob's review feedback on PR #13397 by explicitly marking the three /api/history operations as deprecated in the OpenAPI spec: * GET /api/history -> superseded by GET /api/jobs * POST /api/history -> superseded by /api/jobs management * GET /api/history/{prompt_id} -> superseded by GET /api/jobs/{job_id} Each operation gains deprecated: true plus a description that names the replacement. A formal sunset timeline (RFC 8594 Deprecation and RFC 8553 Sunset headers, minimum-runway policy) is being defined separately and will be applied as a follow-up. * Address Spectral lint findings in openapi.yaml - Add operation descriptions to 52 endpoints (prompt, queue, upload, view, models, userdata, settings, assets, internal, etc.) - Add schema descriptions to 22 component schemas - Add parameter descriptions to 8 path parameters that were missing them - Remove 6 unused component schemas: TaskOutput, EmbeddingsResponse, ExtensionsResponse, LogRawResponse, UserInfo, UserDataFullInfo No wire/shape changes. Reduces Spectral findings from 92 to 4. The remaining 4 are real issues (WebSocket 101 on /ws, loose error schema, and two snake_case warnings on real wire field names) and are worth addressing separately. * fix(openapi): address jtreminio oneOf review on /api/userdata Restructure the UserData response schemas to address the review feedback on the `oneOf` without a discriminator, and fix two accuracy bugs found while doing it. Changes - GET /api/userdata response: extract the inline `oneOf` to a named schema (`ListUserdataResponse`) and add the missing third variant returned when `split=true` and `full_info=false` (array of `[relative_path, ...path_components]`). Previously only two of the three actual server response shapes were described. - UserDataResponse (POST endpoints): correct the description — this schema is a single item, not a list — and point at the canonical `GetUserDataResponseFullFile` schema instead of the duplicate `UserDataResponseFull`. Also removes the malformed blank line in `UserDataResponseShort`. - Delete the now-unused `UserDataResponseFull` and `UserDataResponseShort` schemas (replaced by reuse of `GetUserDataResponseFullFile` and an inline string variant). - Add an `x-variant-selector` vendor extension to both `oneOf` sites documenting which query-parameter combination selects which branch, since a true OpenAPI `discriminator` is not applicable (the variants are type-disjoint and the selector lives in the request, not the response body). This keeps the shapes the server actually emits (no wire-breaking change) while making the selection rule explicit for SDK generators and readers. --------- Co-authored-by: guill --- .gitignore | 1 - openapi.yaml | 3231 ++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 3231 insertions(+), 1 deletion(-) create mode 100644 openapi.yaml diff --git a/.gitignore b/.gitignore index 2700ad5c2..0ab4ba75e 100644 --- a/.gitignore +++ b/.gitignore @@ -21,6 +21,5 @@ venv*/ *.log web_custom_versions/ .DS_Store -openapi.yaml filtered-openapi.yaml uv.lock diff --git a/openapi.yaml b/openapi.yaml new file mode 100644 index 000000000..77d0e2318 --- /dev/null +++ b/openapi.yaml @@ -0,0 +1,3231 @@ +openapi: 3.1.0 +info: + title: ComfyUI API + description: | + API for ComfyUI - A powerful and modular stable diffusion GUI and backend. + + This API allows you to interact with ComfyUI programmatically, including: + - Submitting and managing workflow executions + - Querying node/object information + - Uploading and viewing files + - Managing user settings and data + - Asset management (feature-gated) + + ## Dual-path routing + Every route registered via `self.routes` in the ComfyUI server is available at + both its bare path (e.g. `/prompt`) and an `/api`-prefixed path (e.g. `/api/prompt`). + This spec uses the `/api`-prefixed versions as canonical. + + ## Multi-user mode + When ComfyUI is started with `--multi-user`, the `Comfy-User` header identifies + the active user for settings, userdata, and history isolation.

Date: Sun, 3 May 2026 05:46:15 +0300 Subject: [PATCH 71/81] feat: Gemma4 text generation support (CORE-30) (#13376) * initial gemma4 support * parity with reference implementation outputs can 100% match transformers with same sdpa flags, checkpoint this and then optimize * Cleanup, video fixes * cleanup, enable fused rms norm by default * update comment * Cleanup * Update sd.py * Various fixes * Add fp8 scaled embedding support * small fixes * Translate think tokens * Fix image encoder attention mask type So it works with basic attention * Handle thinking tokens different only for Gemma4 * Code cleanup * Update nodes_textgen.py * Use embed scale class instead of buffer Slight difference to HF, but technically more accurate and simpler code * Default to fused rms_norm * Update gemma4.py
