It is mergeable with explicit owner awareness: the new image model ID should be confirmed with the provider, and the realtime regression test should verify the token’s selected model; the media-generation documentation also needs a small clarification about duration in extend mode.

xAI Imagine API grok-imagine-video-1.5 text-to-video image-to-video reference-to-video 1080p official documentation
💡 Result:
The Grok Imagine Video 1.5 model is xAI's flagship video generation model, accessible via the official xAI Imagine API [1][2]. It supports text-to-video, image-to-video, and reference-to-video workflows [3][4][5]. Key Capabilities and Specifications: - Text-to-Video: Generates video from a text prompt [6][4]. Supports native 1080p resolution [3][2][5]. - Image-to-Video: Uses a single starting image as the first frame, optionally combined with a prompt to guide motion [6][4]. Supports native 1080p resolution [3][2]. - Reference-to-Video: Uses 1–7 reference images to maintain consistency for characters, styles, or objects [2][4][7]. While text and image-to-video support 1080p, reference-to-video is generally documented as supporting up to 720p [4][7]. - Audio: The model automatically generates and synchronizes audio with the video output [8]. API Integration: - Model Identifier: The model is accessed using the identifier grok-imagine-video-1.5 [9][1][5]. - API Endpoint: Video generation requests are handled via the POST /v1/videos/generations endpoint [5][10]. - Workflow: The API is asynchronous; users submit a request and poll the returned request ID for the final video URL [6][5]. The official xAI SDK and Vercel AI SDK automate this polling process [3][6][5]. - Pricing: As of August 2026, the output cost is $0.080 per second of video generation [9][11]. Official documentation and guides are available at docs.x.ai [6][5][10][7].

site:docs.x.ai/developers/model-capabilities/video grok-imagine-video-1.5 reference-to-video
💡 Result:
Grok-imagine-video-1.5 is an advanced video generation model by xAI that supports a specific feature called reference-to-video [1][2]. Reference-to-video allows users to guide video generation by providing reference images, preset voices, or both [2]. Unlike image-to-video, which uses an input image as the starting frame, reference-to-video uses the provided images to incorporate specific people, objects, clothing, or visual elements throughout the video [2]. This functionality is particularly useful for tasks such as virtual try-on, product placement, and character-consistent storytelling [2]. Key technical details for reference-to-video on grok-imagine-video-1.5 include: - Preset Voice Integration: Users can provide up to 3 preset voices using reference_audios, with voice identifiers drawn from xAI's built-in text-to-speech roster [2]. These voices can be tagged in the generation prompt as <AUDIO_0>, <AUDIO_1>, and <AUDIO_2> [2]. - Image Guidance: Users can pass multiple reference images to ensure visual consistency [2]. When used alongside audio, images can be tagged in the prompt (e.g., <IMAGE_0>) to correspond with the references provided [2]. - Resolution: While grok-imagine-video-1.5 supports native 1080p resolution for standard text-to-video and image-to-video tasks, reference-to-video is currently capped at 720p [1][2]. - API Implementation: In the API, this mode is triggered by setting the generation mode to reference-to-video and providing the reference_image_urls or reference_audios [1][2]. For users needing custom voice audio files, this capability is available to trusted partners upon request [2].

Restrict video editing and extension to grok-imagine-video. xAI lists VIDEO input, editing, and extension only for grok-imagine-video; grok-imagine-video-1.5 supports text-to-video, image-to-video, and reference-to-video, but not video input.
- Remove

…eview Address /review-pr findings on #1136: - Reject unknown modelOptions.mode values instead of silently misrouting a source-video body to /videos/generations (wrong endpoint, wrong billing). - Stop leaking raw duration/aspect_ratio/resolution from modelOptions into edit/extend bodies: edit rejects any duration (output inherits the source clip's length) and both modes reject size/aspect_ratio/resolution, matching the documented inherit-from-source semantics instead of sending fields the API ignores. Extend still snaps its added-tail duration. - Hoist mode-exclusivity checks into a dedicated edit/extend path so error messages never give generation-path advice for mode requests. - Throw on unknown image metadata.role strings instead of silently dropping the part (roles arrive untrusted from JSON callers). - Gate reference inputs to grok-imagine-video-1.5 at runtime, and split the provider options per model (GrokVideoBaseProviderOptions vs the 1.5 shape) so v1.0 no longer advertises reference fields at compile time. - Extract GROK_DEFAULT_REALTIME_MODEL so the token issuer and client adapter can't drift apart on future default bumps. - Comment/doc accuracy fixes: 'character' role alias documented, stale xAI URL and file headers refreshed, create-response JSDoc covers all three endpoints, deprecated 1.0 voice ids named in docs, example now requests the native 1080p it advertises. - 10 new tests: unknown mode/role rejection, edit duration/size rejection, extend snapping (modelOptions + generic), combined start-frame+reference body, explicit reference_images override, v1.0 reference gating, 1080p T2V body assertion, realtime token default model.

- Image: add grok-imagine-image-2.0 (xAI's recommended model) with the
2.0-only quality provider option ('low' | 'medium').
- Video: drop the stale image-to-video-only guard on grok-imagine-video-1.5

(role:'reference' image parts -> reference_images, preset voices via

video prompt part + modelOptions.mode ('edit' -> /v1/videos/edits,

Closes#1133…eview Address /review-pr findings on #1136: - Reject unknown modelOptions.mode values instead of silently misrouting a source-video body to /videos/generations (wrong endpoint, wrong billing). - Stop leaking raw duration/aspect_ratio/resolution from modelOptions into edit/extend bodies: edit rejects any duration (output inherits the source clip's length) and both modes reject size/aspect_ratio/resolution, matching the documented inherit-from-source semantics instead of sending fields the API ignores. Extend still snaps its added-tail duration. - Hoist mode-exclusivity checks into a dedicated edit/extend path so error messages never give generation-path advice for mode requests. - Throw on unknown image metadata.role strings instead of silently dropping the part (roles arrive untrusted from JSON callers). - Gate reference inputs to grok-imagine-video-1.5 at runtime, and split the provider options per model (GrokVideoBaseProviderOptions vs the 1.5 shape) so v1.0 no longer advertises reference fields at compile time. - Extract GROK_DEFAULT_REALTIME_MODEL so the token issuer and client adapter can't drift apart on future default bumps. - Comment/doc accuracy fixes: 'character' role alias documented, stale xAI URL and file headers refreshed, create-response JSDoc covers all three endpoints, deprecated 1.0 voice ids named in docs, example now requests the native 1080p it advertises. - 10 new tests: unknown mode/role rejection, edit duration/size rejection, extend snapping (modelOptions + generic), combined start-frame+reference body, explicit reference_images override, v1.0 reference gating, 1080p T2V body assertion, realtime token default model.

Re-applies the review residuals on top of the rebased branch: - Treat JSON-serialized null / empty-array values for duration and the reference fields as unset on every path: the generation branch no longer sends "duration": null or empty reference arrays, and null reference fields no longer trip the v1.0 reference gate; edit/extend destructure the reference fields out of the passthrough so no known key can leak into those bodies. - Name the actual endpoint in create-job failure messages so a failed edit/extension no longer reports as a 'video generation' failure. - Type-tie GROK_VIDEO_REFERENCE_MODELS / GROK_VIDEO_SOURCE_MODELS to the per-model options map so a typo or an unlisted future capable model is a compile error. - Sync the media-generation skill with the current contract (v1.0-only edit/extend, reference caps, 720p reference cap, 1080p on 1.5 only, edit/extend option rejections). - Tests: null-duration strip, null/empty reference normalization, endpoint-named edit failure (124 total).

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Clarify that duration is valid for extend.
The phrase “pass none of them there” can imply that duration is invalid for both modes. The adapter rejects duration only in edit mode and uses it in extend mode as the added-tail length. Clarify this distinction.
