}

Available on crate feature realtime only.

The inner session object carried by the session.update client event.

Fields

model: Option<String>

Model id selected for this session. SessionBuilder fills this from the type-safe model passed to RealtimeClient::session.

input_audio_format: InputAudioFormat

Input audio format (wav, pcm16, or pcm24).

output_audio_format: OutputAudioFormat

Output audio format. The current protocol accepts only pcm.

instructions: Option<String>

System instructions guiding the model.

modalities: Vec<RealtimeModality>

Output modalities. The protocol default is text plus audio.

voice: Option<RealtimeVoice>

Voice used when audio output is requested.

temperature: Option<f64>

Sampling temperature in the inclusive range 0.0..=1.0.

max_response_output_tokens: Option<u16>

Maximum number of response text tokens (1..=1024). None uses the server default ("inf", currently equivalent to 1024).

The upstream schema represents this numeric limit as a JSON string, so custom serde preserves that exact wire shape while callers use a u16.

turn_detection: TurnDetection

VAD strategy.

input_audio_noise_reduction: Option<InputAudioNoiseReduction>

Optional microphone noise-reduction profile.

beta_fields: BetaFields

Beta / mode toggles.

greeting_config: Option<GreetingConfig>

Optional greeting generated when the session starts.

tools: Vec<RealtimeTool>

Function tools advertised to the model.
