Atlas Cloud

Route complete productions through image_selector or video_selector. Call atlas_image or atlas_video directly when the user names Atlas Cloud or an exact Atlas model. Never substitute a direct vendor endpoint for an Atlas request.

Set ATLASCLOUD_API_KEY. The aliases ATLAS_CLOUD_API_KEY and ATLAS_API_KEY are accepted for compatibility.

Preflight every paid call

1. Read tool.get_info()["model_catalog"]; do not infer availability from a search collection or invent a task suffix.
2. Select an exact model id and operation supported by that catalog.
3. Announce the Atlas tool, provider, exact model, request count, and estimated cost before submitting.
4. Use local-path inputs when convenient. The tool uploads them through Atlas.
5. Save outputs inside the active projects/<project-id>/ tree and inspect them.

Video routes

Family	Operations	Exact route notes
Seedance 2.5	text, image, reference	bytedance/seedance-2.5/{text,image,reference}-to-video; image mode uses image plus optional last_image; reference mode accepts up to 30 images, 10 videos, and 10 audios (including audio-only); 4–30s; $0.134/s
Seedance 2.0	text, image, reference	bytedance/seedance-2.0/{text,image,reference}-to-video; 4–15s; $0.112/s
Gemini Omni Flash	text, image, reference, video edit	Standard routes use google/gemini-omni-flash/...; developer routes exist for text/image/reference only. Standard image mode uses one image; standard reference uses images; developer reference requires one video_clips object.
MiniMax H3	text, image, reference	minimax/h3/{text,image,reference}-to-video; image mode supports optional end_image; reference mode requires refers objects; 4–15s; 768P/2K; $0.10/s

Use canonical OpenMontage fields:

tool.execute({
    "prompt": "...",
    "model": "minimax/h3/reference-to-video",
    "operation": "reference_to_video",
    "duration": 10,
    "resolution": "2K",
    "reference_images": ["projects/demo/character.png"],
    "reference_audios": ["projects/demo/performance.wav"],
    "output_path": "projects/demo/h3.mp4",
})

For Gemini developer reference video, pass video_clips objects with url, start, and ends. For H3, callers may pass normalized reference_images, reference_videos, and reference_audios; the tool converts them to refers.

Do not silently clamp duration, resolution, or ratio. Invalid values must fail before billing with the supported choices in the error.

Image routes

Family	Operations	Exact route notes
Seedream 5.0 Pro	generate, edit, decompose	bytedance/seedream-v5.0-pro/text-to-image, /edit, /layer-decomposition; edit accepts up to 10 images; sizes use WIDTH*HEIGHT
Seedream 5.0 Lite	edit	bytedance/seedream-v5.0-lite/edit; no live Lite text-to-image sibling is assumed; accepts up to 14 images
GPT Image 2	generate, edit	openai/gpt-image-2/text-to-image, /edit; sizes use WIDTHxHEIGHT; edit accepts up to 10 images
Nano Banana 2	generate, edit	google/nano-banana-2/text-to-image, /edit; uses aspect ratio plus 1k/2k/4k resolution; edit accepts up to 14 images

Set generation_mode to generate, edit, or decompose. Source images can be supplied as image_path, image_paths, image_url, or image_urls.

tool.execute({
    "prompt": "Replace the packaging with matte cobalt glass; preserve the logo",
    "model": "google/nano-banana-2/edit",
    "generation_mode": "edit",
    "image_paths": ["projects/campaign/source.png"],
    "resolution": "2k",
    "output_path": "projects/campaign/revised.png",
})

Result and failure contract

Both tools submit to Atlas, poll the returned prediction id, download every output, and return ToolResult provenance containing the provider, exact model, prediction id, submitted parameters, source URL, artifact paths, and estimated cost. A missing key, unsupported route, invalid enum, missing media input, failed prediction, timeout, or download failure must return a failed result without switching providers.
