Models

Tributary gives you access to 280+ models from 40+ organizations through a single API.

All models are accessed through the same OpenAI-compatible endpoint. The only thing that changes between providers is the model parameter.

Model ID format

Model IDs follow the format org:model, where org is the organization slug and model is the model slug.

deepseek:deepseek-v4-pro
deepseek:deepseek-v4-flash
moonshot-ai:kimi-k2.6
qwen:qwen3.6-35b-a3b

You can browse the full catalog on the models page, or query it programmatically using the /openai/v1/models endpoint below.

Response format

The GET /openai/v1/models endpoint returns an OpenAI-compatible list of all available models. No authentication is required (you're welcome!)

{
  "object": "list",
  "data": [
    {
      "id": "deepseek:deepseek-v4-pro",
      "object": "model",
      "created": 1777000679,
      "owned_by": "deepseek"
    },

  ]
}

1. List all models

Fetch every available model from the Tributary API.

import OpenAI from "openai";

});

const models = await client.models.list();

for (const model of models.data) {
    console.log(model.id, model.owned_by);
}

2. Use a model

Pass any model ID from the list to make a chat completion request.

const completion = await client.chat.completions.create({
    model: "anthropic:claude-opus-4.6",
