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):
- If the string is a UUID, look up by primary key
id.
- 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.

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).

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.
