Multi-model

How Rimp routes prompts across 8 modalities and ~60 models, and how to compare them side-by-side in one call.

The headline feature: send a single prompt to N models and get all results in one structured response. No more juggling Replicate, OpenAI, Runway, ElevenLabs, and a dozen other dashboards to find which model handles your use case best.

Rimp spans 8 modalities behind one API key and one credit balance:

Modality	Endpoint	Mode	What it does
Image	POST /v1/images	sync 200	Text-to-image and image-to-image
Video	POST /v1/videos	async 202	Text-to-video and image-to-video
Voice	POST /v1/voice	sync 200	Text-to-speech, voice cloning, transcription
Music	POST /v1/music	async 202	Full songs, with or without vocals
Avatar	POST /v1/avatars	async 202	Talking avatars and lipsync
Chat	POST /v1/chat	sync 200	LLM chat completions
3D	POST /v1/three-d	async 202	Text-to-3D and image-to-3D (GLB meshes)
Upscale	POST /v1/upscale	async 202	Image upscaling and face restoration

Costs below are in credits — Rimp’s universal currency (≈ 1,000 credits per $1 of underlying provider cost). The figures are the base cost per unit, exactly as shown in Studio; your wallet debit then applies your plan’s margin multiplier (Free ×1, Pro & Studio ×1.6, Team ×1.3). Call GET /v1/models for the live catalog. cr = credits.

Models tagged Studio+ require a Studio or Team plan. Calling them on Free or Pro returns 402 plan_upgrade_required.

Comparison API

Send one prompt to several models at once. Works across any models that share a modality.

const cmp = await client.comparisons.create({
  prompt: 'cinematic portrait of a fisherman at golden hour, 35mm film',
  models: ['flux-pro', 'imagen-4', 'ideogram-v2'],
  params_shared: { aspect_ratio: '1:1' },
});

Atomic credit reservation

Rimp sums the estimated cost of all N models and reserves it in one transaction. If your wallet can’t cover the sum, you get 402 Insufficient credits and nothing is charged — not even the models that would have fit.

Plan limits

The number of models per comparison is capped by your plan:

Plan	Max models per comparison
Free	2
Pro	3
Studio	6
Team	12

Polling vs webhooks

A comparison returns 202 with a parent comparison object. Two ways to wait for results:

SDK helper

const result = await client.comparisons.waitFor(cmp.id);
// resolves when all child generations reach a terminal state
result.generations.forEach((g) => console.log(g.model, g.outputs[0]?.url));

Fetch the full result any time with GET /v1/comparisons/{id} — it returns the parent plus every child generation (status, charged credits, and signed output URLs).

Capability matrix

Not every model supports every operation. Check the capabilities array on each model (visible in the tables above and in GET /v1/models):

{
  "slug": "flux-pro-i2i",
  "modality": "image",
  "capabilities": ["image_to_image"]
}

Common capabilities: text_to_image, image_to_image, text_to_video, image_to_video, text_to_voice, voice_clone, transcription, text_to_music, lipsync, text_to_text, tool_use, multimodal_input, text_to_3d, image_to_3d, rigged_3d, image_upscale, face_restore.
