What are Models
Models are the AI systems that do the actual generation. Get3W exposes models from 25 providers behind one API and one addressing scheme.
Model Slugs
Every model is addressed by a three-part slug:
{provider_id}/{model_id}/{run_type}Examples:
google/nano-banana-pro/text-to-imagebytedance/seedance-2/reference-to-videominimax/music-2.6/text-to-musictripo/p1/image-to-3d
The slug is also the request path, so the model you want is the endpoint you call:
POST /v1/google/nano-banana-pro/text-to-imageThe same model_id can support several run types. alibaba/wan-3 for instance handles text-to-video, first-to-video, first-last-to-video, and reference-to-video — the run type you pick determines which inputs are required.
Run Types
| Run type | Input → Output |
|---|---|
text-to-image | Prompt → image |
image-to-image | Image + prompt → image (edit, upscale, restyle) |
text-to-video | Prompt → video |
first-to-video | First frame + prompt → video |
first-last-to-video | First and last frame + prompt → video |
reference-to-video | Reference images + prompt → video |
video-to-video | Video + prompt → video |
digital-human | Portrait + audio → talking avatar video |
text-to-speech | Text → audio |
text-to-music | Prompt → music |
speech-to-text | Audio → transcribed text |
text-to-3d | Prompt → 3D model |
image-to-3d | Image → 3D model |
text-to-panorama | Prompt → 360° panorama |
image-to-panorama | Image → 360° panorama |
chat | Messages → text (OpenAI-compatible) |
Providers
Models come from Alibaba, Anthropic, Bilibili, Black Forest Labs, ByteDance, ElevenLabs, Google, Ideogram, JD, Kling, Lightricks, Midjourney, MiniMax, OpenAI, PixVerse, Recraft, Runway, SkyReels, Tencent, Topaz, Tripo, Vidu, xAI, Ace Step, and Get3W's own models.
The provider_id in a slug identifies who made the model, not which infrastructure serves it. A single slug can be served by several upstream platforms, and Get3W fails over between them within one task — see How Get3W Works.
Channels
Many models accept a channel in the request body to select a service tier:
{
"prompt": "A sunset over mountains",
"channel": "stable"
}The common set:
| Channel | Trade-off |
|---|---|
economy | Cheapest, best for bulk work |
stable | Balanced speed and reliability |
official | Direct official provider access |
Some model families use their own values instead — for example turbo / balanced / quality on Ideogram, turbo / pro on Vidu, pro / fast on Lightricks, and standard / human where a real-person path exists. Omit channel and Get3W applies that model's default.
Channel affects price, latency, and which upstream providers are eligible, so it is worth benchmarking before settling on one.
Parameters
Each model has its own input schema. Parameters that recur across many:
| Parameter | Description | Typical use |
|---|---|---|
prompt | Text description of the output | Most models |
image_url / image_urls | Input image(s) | Image and video models |
video_url / video_urls | Input video(s) | Video-to-video, reference-to-video |
aspect_ratio | Output framing, e.g. 16:9 | Image and video models |
resolution | Output resolution, e.g. 1k, 720p | Image and video models |
duration | Video length in seconds | Video models |
output_format | File format, e.g. png | Image models |
seed | Seed for reproducibility | Many models |
channel | Service tier | Where supported |
TIP
Parameter names, allowed values, and defaults vary per model. Each model's page on get3w.com/models lists its full schema. Sending an unsupported value returns 1401 Invalid Parameter in the task result.
Pricing
Price depends on the model, the channel, and output characteristics such as resolution and video duration. Your account tier can discount it further, per model. Every request is priced before it is queued and your balance is checked, so an underfunded call fails fast with 402 rather than running and overdrawing. See How Pricing Works.
Finding Models
Browse the full catalog with filters at get3w.com/models. Each model page shows its slug, supported run types, channels, parameters, and price.
For chat models specifically, there is an OpenAI-compatible listing endpoint:
curl "https://api.get3w.com/v1/models" \
-H "Authorization: Bearer YOUR_API_KEY"This returns only the chat models, matching what OpenAI clients expect from /v1/models. Generation models are not included — use the models catalog on the website for those.
