Live rates from the EmpirioLabs catalog for both models. Each rate card always matches what the API charges.
Request parameters each model lists on EmpirioLabs, with the allowed values or range where one applies. A dash marks a parameter the model does not list.

Full-duplex voice over a WebSocket at wss://api.empiriolabs.ai/v1/realtime?model=qwen-audio-3-0-realtime-flash, authenticated with the ordinary Authorization Bearer header. Configure the session with session.update over the socket: voice, instructions, modalities, turn detection and delivery.
speed (0.5 to 2) sets the speaking rate, enable_speech_emotion the expressive delivery, and max_history_turns (1 to 50) how many earlier exchanges the model reads. Ask for the reply's language in your instructions.
The voices on this model are its own set. Pick one from the voice list rather than carrying a voice across from another model, or leave it unset and the default is supplied for you.
Web search is off by default. Turn it on with enable_search. It cannot be enabled in the same session as function calling, and search results are added to the conversation and count as input tokens.
Audio and text tokens are priced separately in both directions. A spoken reply is billed for its audio output tokens only, and the text output rate applies to replies with no audio. Each completed turn is billed on its own from the usage the model reports.

Qwen Audio 3.0 Realtime Flash holds a live conversation over a WebSocket at wss://api.empiriolabs.ai/v1/realtime?model=qwen-audio-3-0-realtime-flash, not over the HTTP endpoints. Connect with the model id qwen-audio-3-0-realtime-flash and send your EmpirioLabs API key as an Authorization: Bearer header on the handshake. Audio travels both ways as base64 16-bit PCM. A browser cannot set headers on a WebSocket, so open this connection from your server and relay audio to the browser over your own socket. Both models are called through the same endpoint. Set model to qwen-audio-3-0-realtime-flash or qwen-audio-3-0-realtime-plus. Get an API key from the EmpirioLabs dashboard.

Both models were released on Aug 10, 2026. Both models have a context window of 16K tokens. Qwen Audio 3.0 Realtime Flash lists the lower rate for Input: audio (per 1M audio input tokens) and Input (per 1M prompt tokens). The specs, rate cards, and parameters on this page come from the live EmpirioLabs catalog.
Qwen Audio 3.0 Realtime Flash lists the lower rate for Input: audio (per 1M audio input tokens) and Input (per 1M prompt tokens). Both live rate cards are on this page and always match what the API charges.
Yes. Both models use WEBSOCKET /v1/realtime with the same EmpirioLabs API key, so most integrations switch by changing the model value. Check the parameters table on this page first if you rely on a model-specific parameter.
Yes. Open each model in the EmpirioLabs playground and press Start session to try it in your browser.
