📝 WalkthroughWalkthroughAdds an asynchronous OpenRouter video adapter with model metadata, typed options, polling, image-role mapping, authenticated downloads, data-URL results, and cost usage. Tightens OpenRouter image validation, updates examples and tests, and expands documentation and model synchronization. ChangesOpenRouter video adapter and image fixes
Estimated code review effort: 4 (Complex) | ~60 minutes Mergeability Score:🟡 Moderate · up to This PR adds OpenRouter video generation and image follow-ups, but unsupported video options and a listed model can still reach users without a working request path. Merge should wait for those bounded correctness issues to be fixed or explicitly accepted; the remaining documentation and test-layout items are follow-up cleanup. Sequence Diagram(s)sequenceDiagram

cancellation consistently when the gateway/CDN is slow.
- Around line 118-147: The video adapter in the OpenRouter path is validating
only start/end frame images, but it still forwards reference/character images
without checking whether the model supports reference conditioning. Update the
input classification logic in the same function that handles `starts`, `ends`,
and `references` to validate `reference` / `character` images against the model
metadata before building `inputReferences`, and throw a local error when the
model does not support them, consistent with the existing
`getVideoModelMeta(model)?.frameImages` checks.
- Around line 281-310: Add runtime validation for the model-specific

values for `this.model` (using the existing video metadata/helpers if available)
instead of only casting them in the `request` assembly. Keep the current
`request` shape in the video generation path, but ensure unsupported values are
rejected before `VideoGenerationRequest` is sent.

Validate reference-image support before forwarding inputReferences.
Frame images are checked against model metadata, but reference / character inputs are always accepted. For models that do not support reference/image conditioning, this submits an invalid provider request instead of failing locally as the adapter promises.

This is a horrible workaround that claude added. It's needed as the sdk isn't downloading video properly. don't merge like this
…e activity follow-ups Closes#707. - Add openRouterVideo: async jobs adapter for OpenRouter's dedicated video API (submit -> poll -> download). Per-model size/duration/option types are generated from GET /api/v1/videos/models; frame roles map onto frame_images[] / input_references[] per the MediaInputRole taxonomy. - Teach the model-meta sync scripts the videos/models endpoint (openrouter.video-models.json + OPENROUTER_VIDEO_MODEL_META). - Image adapter follow-ups from the #624 review: throw on unmapped sizes (the size union used a Unicode multiplication sign so every non-square size silently dropped its aspect ratio), throw on numberOfImages > 1 (live-verified: the gateway ignores all count keys), expose image_config.strength. - Completed videos are returned as data: URLs (unsigned_urls 401 without the API key header) with gateway-reported cost on usage.cost. The SDK's getVideoContent is bypassed: its matcher only accepts application/octet-stream while the endpoint serves video/mp4. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The getVideoContent response-matcher bug is still present in 0.12.79 (the stream matcher only accepts application/octet-stream while the endpoint serves video/mp4), so the direct unsigned-URL download stays.

Wire openRouterVideo onto the shared typed-duration contract (the same one geminiVideo uses): add the sixth BaseVideoAdapter generic (OpenRouterVideoModelDurationByName), narrow `duration` per model from the published `/api/v1/videos/models` metadata, and override availableDurations() / snapDuration() (backed by snapToDurationOption). `duration` is now a compile-time per-model union; the runtime validateVideoDuration backstop stays for JS callers and unknown-meta models. - video-provider-options.ts: OpenRouterVideoModelDurationByName + getVideoDurationOptions (discrete from meta, none when unknown/empty) - adapter: 6th generic, createVideoJob narrowed to per-model size/duration, availableDurations()/snapDuration() overrides - export OpenRouterVideoModelDurationByName from index - tests: 4 introspection cases; existing negative size/duration tests now use @ts-expect-error (proves the union rejects them) while still asserting the runtime throw - docs/media/video-generation.md, docs/adapters/openrouter.md, media-generation SKILL.md: document snapDuration/availableDurations for OpenRouter; bump updatedAt; changeset Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…o typed-duration constraint ts-react-media now demos openRouterVideo alongside fal: - add @tanstack/ai-openrouter dep - Seedance 2.0 (text-to-video) and Veo 3.1 (image-to-video) model entries - switch cases showcasing adapter.snapDuration() to coerce raw UI seconds to the model's nearest supported duration (Seedance 7→7, Veo 3.1 7→6) - videoAdapterForModel() resolver routes the poll/status path to the right adapter (the helpers were hardcoded to falVideo) Building the example surfaced a pre-existing bug in the #624 typed-duration contract: generateVideo()'s `TAdapter extends VideoAdapter<string, any, any, any>` bound let the sixth (duration) generic fall back to its `Record<string, number>` default. Because VideoAdapter.createVideoJob is a contravariant function-valued property, no adapter whose `duration` is a per-model literal union (Veo `4|6|8`, Seedance `4..15`) satisfied the bound — so even the documented `generateVideo({ adapter: geminiVideo('veo-3.1-...') })` failed to type-check. Widen the bound to leave size/duration unpinned at all 10 activity sites; per-model types are still recovered via inference (VideoSizeForAdapter / VideoDurationForAdapter). Adds a compile-only regression test and an @tanstack/ai changeset. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…doc type-check The new kiira doc-typecheck (#805) type-checks fenced TS samples. The OpenRouter snapDuration snippet referenced generateVideo/openRouterVideo/sliderSeconds without imports or a declaration; add them so the snippet type-checks standalone.

…ass comment
Live-verified against @openrouter/sdk 0.12.79: getVideoContent still rejects the
real 'video/mp4' response ('Unexpected Status or Content-Type') even though the
body is a valid MP4, so the manual authenticated download (and its injectable
fetch seam) stays. Only the comment's stale 0.12.35 reference was wrong.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>…eoContent Rebase #740 onto current main (rerank, BytePlus, Grok video, Omni Flash) and finish the leftover wiring: - Download completed clips via @openrouter/sdk 0.13.20 getVideoContent (it now accepts video/mp4) instead of the unsigned-URL fetch bypass - Keep the example on the streaming generateVideoFn path and add an OpenRouter provider group in ts-react-media - Merge OpenRouter into the current video/image docs and skill without dropping newer providers; kiira snippet uses the typed byteplus key - Drop the generateVideo duration-constraint changeset (already on main)

e813487 to
243ebf1Compare…ideos/models Snapshot is now 23 models (was 14). Adds HappyHorse 1.0/1.1, FLUX.3 Video, Seedance 2.0 Mini / 2.5, Hailuo 3, Runway Aleph 2 / Gen-4.5, and Grok Imagine Video 1.5, plus capability updates on existing entries (e.g. Seedance 2.0 4K sizes, Sora 2 Pro 16/20s). Chat catalog left unchanged.
../utils emits as ../utils.js in .d.ts and does not resolve to utils/index.d.ts under bundler/node16. Match the image adapter and import from ../utils/client. Also commit openrouter.video-models.json in the nightly sync-models workflow so the video snapshot stays with model-meta.

In `@docs/media/image-generation.md`:
- Around line 297-304: Update the role-mapping table entries for character,
start_frame, and end_frame to reflect the implemented Gemini video adapter
mappings, removing the stale “planned” and “no Veo adapter yet” qualifiers while
preserving the existing referenceImages, image, and lastFrame targets.
- Around line 35-44: Update the generic OpenAI image-generation examples using
generateImage and openaiImage to use the gpt-image-2 model instead of dall-e-3,
and access result.images[0]?.b64Json rather than the URL field because this
model returns base64 data. Leave examples explicitly specific to DALL-E 3
unchanged.
In `@docs/media/video-generation.md`:
- Around line 497-507: Update the generateVideoStreamFn input type so size uses
the supported literal union, then pass data.size directly to generateVideo
without an any assertion; keep duration typed as number.
In `@packages/ai-openrouter/src/model-meta.ts`:
- Around line 16181-16190: Update the duration handling associated with the
model metadata entry and snapToDurationOption() so numeric durations are sorted
ascending before tie-based selection. Ensure availableDurations() also returns
durations in ascending order rather than exposing source declaration order.
- Around line 16251-16260: Update the `runway/aleph-2` entry and
`createVideoJob` flow so source-video prompt parts are accepted and mapped into
the OpenRouter request according to Aleph 2’s editing API; otherwise remove
`runway/aleph-2` from `OPENROUTER_VIDEO_MODELS` until video inputs are
supported.
In `@packages/ai-openrouter/tests/video-adapter.test.ts`:
- Around line 1-3: Move the video adapter unit test next to the
createOpenRouterVideo source module under src/adapters, then update its relative
import paths so the test continues resolving adapter-internals and the video
implementation from its new location.

🌐 Web query:
OpenAI gpt-image-2 Images API default response b64_json or url
💡 Result:
When using the OpenAI gpt-image-2 model via the Images API, the response format is base64-encoded image data by default [1][2]. The response_format parameter (which allows choosing between url or b64_json) is not supported for gpt-image-2 or other GPT image models; these models always return images as base64-encoded data [2][3][4]. Consequently, a url response format is not available for gpt-image-2 [2][5]. For image output configuration, you can specify the output_format as png, jpeg, or webp [1][2][3]. If jpeg or webp is selected, you can also control the compression level using the output_compression parameter [1][3].

Sort numeric durations in the converter.snapToDurationOption() uses input order for equal-distance ties: 7 snaps to 8 for [8, 4, 6] but to 6 for [4, 6, 8]. availableDurations() also exposes the source order directly.

OpenRouter runway/aleph-2 video API input video prompt parts in-context video editing
💡 Result:
OpenRouter provides access to the Runway Aleph 2.0 video editing model (model slug: runway/aleph-2) via its unified API [1][2]. Aleph 2.0 is an in-context video editing model designed to modify existing video clips based on text instructions and optional image-based keyframe guidance, while preserving details outside the scope of the requested changes [1][3][4]. Key input components for the Aleph 2.0 API include: 1. Prompt: A text description (up to 1000 characters) specifying the edits to apply (e.g., changing objects, lighting, or styles) [5][6][4]. 2. Input Video: A source video clip, typically accepted as a URL or data URI, with supported durations often ranging from 2 to 30 seconds [5][6][4]. 3. Keyframe-Guided Editing (Optional): This allows for precise control over the edit at specific moments in the video [5][4]. Users can provide up to 5 reference images, each anchored to a specific position in the clip [5][6][4]. - Anchors can be defined by named positions (e.g., first or last frame) or by precise timestamps in seconds [5][4]. - This enables the model to interpolate between different states or lock a specific look at a defined point in the video [5][4]. OpenRouter supports these video generation and editing requests through its standard video generation API endpoint [7][8]. Developers can integrate Aleph 2.0 by using the OpenRouter API, which is designed to be OpenAI-compatible, requiring only a swap of the base URL and the specification of the correct model slug [1]. For detailed integration, users should refer to the OpenRouter documentation on submitting video generation requests [9][8].

Make OpenAI URL-based edit examples opt in to URL fetching.
The examples pass HTTP(S) image URLs to openaiImage("gpt-image-2"). This document states that OpenAI /images/edits rejects HTTP(S) URLs by default. Use data: sources or an adapter with allowUrlFetch: true; otherwise, copied examples will throw. (tanstack.com)

Validate resolution and aspectRatio at runtime.
Lines 161-187 validate only size and duration. createVideoJob forwards modelOptions.resolution and modelOptions.aspectRatio directly to OpenRouter. A JavaScript caller or runtime-derived configuration can submit unsupported values for a known model.

Log result2 for the Imagen example.
Lines 63-66 store the Imagen response in result2, but Line 68 logs result, which belongs to the preceding Gemini native request. The snippet does not display the Imagen result it describes.

Validate resolution and aspectRatio at runtime.
The type unions restrict TypeScript callers, but createVideoJob validates only size and duration. JavaScript callers and dynamically sourced options can send an unsupported resolution or aspectRatio to OpenRouter.
Add metadata-based validators for both fields. Invoke them before request construction with validateVideoSize and validateVideoDuration.

Update the OpenRouter example to bytedance/seedance-2.5.
bytedance/seedance-2.5 is the newest ByteDance video model in packages/ai-openrouter/src/model-meta.ts; line 575 uses the older bytedance/seedance-2.0.

Do not expose runway/aleph-2 until the adapter supports source video.
runway/aleph-2 is an in-context video editing model. The supplied createVideoJob implementation rejects every video prompt part before it creates the request. Consumers can select this model but cannot use its supported workflow.
Exclude this model from OPENROUTER_VIDEO_MODELS, or implement video prompt mapping end to end.
