Models

The model catalog is publicly accessible — no authentication required. It lists every active model with its DA pricing, supported capabilities, and provider metadata.

Fetch the catalog#

const res = await fetch("https://opendunes.com/api/models");
const { data } = await res.json();

for (const model of data) {
  console.log(model.slug, model.pricing.input_da_per_million, "DA / M tokens");
}

GET /api/models returns a paginated array. Each object includes:

Query parameters#

// List free vision-capable models sorted by context length
const res = await fetch(
  "https://opendunes.com/api/models?free=true&capability=vision&sort=context&order=desc"
);

Single model#

const res = await fetch("https://opendunes.com/api/models/meta-llama/llama-4-maverick");
const model = await res.json();
console.log(model.context_length); // e.g. 128000

Facets and stats#

Two utility endpoints help build filter UIs without scanning the full catalog:

• GET /api/models/facets — returns aggregated filter options (providers, capabilities, modalities) with counts.
• GET /api/models/stats — returns catalog-wide statistics (total models, free count, newest additions).

Browse in the UI#

Explore and compare models visually at /models. The catalog page respects the same filters.
