# Supported models & providers

> Catalog of LLM, TTS, and STT names for Kupe agents and APIs (aligned with app.kupe.in).

## Overview

Kupe supports the models and voices below. When configuring an agent via **`PUT /api/v1/agents/{agent_id}`** (or after **`POST /api/v1/agents/simple`**), prefer **`agent_model_config.model_name`**, **`tts_config.tts_model_name`**, and **`transcriber_config.transcriber_model_name`** (legacy `*_provider_id` / `provider_id` still work). Values are **catalog codes** or row UUIDs — the server resolves to internal ids before saving.

**Resolution order** (server-side when creating or updating an agent):

1. If the string is a **UUID**, look up by primary key **`id`**.
2. Otherwise resolve by **catalog fields** (LLM `model_name`, TTS `model_name` / `provider_name` / `provider:model`, STT `model_name` or `name`). Ambiguous names prefer the row marked **`is_default`**, then a stable sort by `id`.

Authoritative list for your tenant: **`GET https://api.kupe.in/api/v1/providers/model`**, **`.../tts`**, **`.../stt`** with your `x-api-key`. This page mirrors the product catalog; drift is possible until you refresh from the API.

See also: [Model providers](/docs/assistants/model-providers) (language codes + create-agent field notes), [Voice Agent HTTP API](/docs/voice-agent-api), and the **API reference** tab ([introduction](/docs/api-reference/introduction)).

## Voices (TTS)

Use these as **`voice_name`**, set **`tts_config.tts_model_name`** to the TTS row `id` or a catalog match from **`GET /api/v1/providers/tts`**, and optionally **`tts_config.language`** (stored as `voice_parameters.language`).

    | `jacqline` |

    | `carolina` |
    | `blake`    |
    | `ronald`   |
    | `jake`     |
  </div>

  <div className="provider-section">
    ### <img src="https://app.kupe.in/images/logo_providers/deepgram.jpeg" width="28" height="28" style={{verticalAlign: 'middle', marginRight: '0.5rem', display: 'inline-block'}} /> Deepgram

    | Voice name  |
    | :---------- |
    | `thalia`    |
    | `aries`     |
    | `apollo`    |
    | `andromeda` |
    | `asteria`   |
  </div>
</div>

## Transcribers (STT)

Use **`transcriber_config.transcriber_model_name`** as the STT row `id` or a matching **`model_name` / `name`** from **`GET /api/v1/providers/stt`** (legacy **`provider_id`** is the same value), plus **`transcriber_config.language`**. The API stores the pipeline STT model id from that catalog row — it is **not** a separate field on create. Prefer **`language`** as a string (e.g. `hi-IN`); a single-element array is coerced.
