MODELS
All available models on CallMissed — Sarvam AI for STT/TTS/LLM, and 300+ text models via OpenRouter. All accessible through one OpenAI-compatible API.
Overview
CallMissed provides access to two model providers through a single OpenAI-compatible API:
- Sarvam AI — purpose-built for Indian languages. STT, TTS, and LLM optimized for Indic languages (Hindi, Tamil, Telugu, Bengali, and 18 more).
- OpenRouter — 300+ text models from every major provider (OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, and more) through one endpoint.
