Mistral
Voxtral TTS
voxtral-tts
Parameters: 4BQuantization: None (served in BF16)Capabilities: Text-to-speech synthesis — converts text into natural-sounding spoken audioAudio Format: Returns generated audio via the /v1/audio/speech endpoint with model=voxtral-ttsBest for: High-quality voice output for assistants, narration, and accessibility, kept inside a secure enclaveModel weights: mistralai/Voxtral-4B-TTS-2603Configuration repo: tinfoilsh/confidential-realtime-models
Qwen
Qwen3 TTS

Mistral
Voxtral Mini Realtime
voxtral-mini-4b-realtime
Parameters: 4BQuantization: None (served in BF16)Capabilities: Streaming speech-to-text transcription — partial transcripts appear word-by-word as audio arrives (~480ms behind the speaker)Audio Format: PCM16 mono over WebSocket (16kHz native; 24kHz accepted on the OpenAI-compatible endpoint and resampled in-enclave)Languages: English, Chinese, Hindi, Spanish, Arabic, French, Portuguese, Russian, German, Japanese, Korean, Italian, DutchBest for: Live dictation, voice interfaces, and any UI that should show words as they’re spoken rather than after the recording endsModel weights: mistralai/Voxtral-Mini-4B-Realtime-2602Configuration repo: tinfoilsh/confidential-realtime-models
This model is picky. Realtime transcription streams over a WebSocket, which currently can only be verifiably connected to using the tinfoil-js SDK, and only in Node, so not in browsers. If this is a problem, contact us.
Streaming by architecture: Causal audio encoder emits text incrementally with a fixed lookahead — transcripts are append-only and never revised. Served over the WebSocket /v1/realtime endpoint, including an OpenAI Realtime API-compatible mode. See the realtime section of the processing audio guide.
