Image items process asynchronously — check get_style_kit until assetStatus is \"ready\" before relying on it in a generation. When adding several items, complete every addition first, then call get_style_kit once to show the final widget; do not wait for image processing.",

"description": "Create or edit a image using Artlist. Use for a user-authorized Artlist generation or editing request. Use an active or named style kit when applicable. Image-to-image: pass `input: { assetId }` (an uploaded image from upload_image / confirm_upload) or `input: { generationId, outputIndex? }` (edit a previous generation's output — never re-upload it; outputIndex defaults to 0). When editing, write a MINIMAL prompt naming ONLY the change and instructing the model to keep everything else identical — do NOT re-describe the whole image, or the model regenerates the entire frame and loses the original. Multi-reference (combine/style-transfer): pass an ARRAY — `input: [{ assetId }, { generationId }, ...]` — sources can be mixed; check get_model_config's referenceInput.maxReferences for the model's limit. To keep editing a result, pass the NEWEST generationId each call returns. For image-to-image pass an i2i-capable model: an I2I modelId from list_models, or a modelGroupId (auto-routes to the I2I variant when a reference is present). Saved references: pass `input: { referenceId }` (from list_references) to generate with one of the user's saved characters, props or locations — or an array, `input: [{ referenceId }, { referenceId }]`, to combine several; with two or more, the prompt must say which is which positionally, since the model cannot tell them apart by name. Not every model can hold a saved reference's identity, so let routing choose: name NO model and it picks a capable one, reporting the switch as `referenceReroute` (the price and the model's valid settings change with it). If you DO name a model — `modelId` or `modelGroupId` — that cannot hold one, nothing is generated and no credits are spent: it returns `reference_unsupported_model`, and you either re-call without the reference to keep that model or drop the model and let it route. Wrapping a saved reference in `startFrame`/`endFrame` does not get around this. Optional `settings` are validated against get_model_config; omitted keys use the model's defaults, echoed back as `resolvedSettings`. To generate multiple variations in ONE call (e.g. \"5 images of X\"), set `settings: { num_images: N }` up to the model's max (see get_model_config); the result renders them together. Returns { status: \"queued\", generationId } — immediately call get_generation_status with that generationId.

Pinning modelId together with styleKitId is not recommended — a pinned model does not auto-route to a multi-reference variant the way a bare modelGroupId/default does, so a single-image-only model plus a kit with 2+ ready images can hit the model's reference cap.

Call get_model_config to see the available genre/mood/theme/tempo/duration dropdown settings and vocals mode (auto-generated lyrics, custom lyrics via a `song_lyrics` setting, or instrumental), and pass chosen values via `settings` to refine the prompt further — but settings alone never substitute for a prompt.

Image-to-video: pass `input: { assetId }` (uploaded image) or `input: { generationId, outputIndex? }` (animate a previous generation's image output — never re-upload it), plus an i2v-capable model: an I2V modelId from list_models or a modelGroupId that auto-routes. Multi-reference video (combine subjects/styles from several references): pass an ARRAY — `input: [{ assetId }, ...]` — which selects the group's multi-reference variant (priced differently; the queued response echoes the price); check get_model_config's referenceInput.maxReferences. References can be images, videos, AND/OR audio: pass a video's assetId (from upload_video) for video-to-video / reference-to-video, an audio assetId (from upload_audio) for audio-driven / lipsync video, and mix any of them in the array freely (e.g. Seedance R2V, image + audio for a talking character). Use the uploaded video/audio directly — do NOT extract a frame or transcode. A video/audio reference needs a model that supports it (Seedance R2V is multi-to-video; the authority is get_model_config's videoReferenceInput / audioReferenceInput — pass its modelGroupId to auto-route). For audio-driven video, set `generate_audio: true` when get_model_config marks it supported. Start/end-frame interpolation: pass `input: { startFrame: ref, endFrame?: ref }` (each an image assetId or generationId) to interpolate between two frames; start alone is image-to-video, end requires start, and it needs a frames-capable model (get_model_config.frameInput). Draft mode: when get_model_config reports draftMode (Seedance 2.5), 480p makes a cheap draft that render_draft later renders in 1080p as the same take (within 7 days). Cost scales with `duration` — use the length the user asked for, or the model's default when they didn't say. Saved references: pass `input: { referenceId }` (from list_references) to animate one of the user's saved characters, props or locations — or an array, `input: [{ referenceId }, { referenceId }]`, to combine several; with two or more, the prompt must say which is which positionally, since the model cannot tell them apart by name.

Prefer the direct upload tools first; open this panel only as a fallback when that path fails or the client can’t deliver the bytes. The user picks and uploads in the panel (it uploads straight from their browser). The panel NEVER tells you the assetId directly: the moment the user’s next message says they uploaded something, call get_recent_uploads to fetch the confirmed assetId(s), then continue the existing user-authorized request with those assets. Preserve all applicable cost confirmation and voice-cloning consent requirements; uploading a file does not itself authorize a new generation or charge. `type` restricts what they can pick (default auto — image, video, or audio), `maxFiles` (default 1) allows several references at once for multi-reference models, `label` titles the panel (e.g. \"Add your voice sample\"). In clients without interactive panels (Claude Code / Cursor), use upload_image / upload_video / upload_audio.",
