How long can a live agent session remain open for?

[xuanyang15]

I have a streaming tool that needs to continuously monitor something for long periods of time, and I was wondering how long the session could remain open for without manual user input as well as whether the time it remains open for counts towards the free tier quota for Gemini Live.

Thank you!

Response from ADK Answering Agent (experimental, answer may be inaccurate)

TLDR: Live agent session duration depends on the session type (audio-only or audio-video) and compression. The free tier for Gemini Live is based on the number of sessions, not their duration.

Hello! I can provide some information on your questions about Gemini Live agent sessions.

Session Duration:

The maximum duration of a live agent session without manual user input depends on whether you are using compression and the type of media being streamed.

• Without compression:
  • Audio-only sessions have a time limit of 15 minutes.
  • Audio-video sessions have a time limit of 2 minutes.

If you exceed these limits, the session will be terminated. [1]

Free Tier Quota:

The time a live agent session remains open does not count toward the free tier quota for Gemini Live. The free tier is limited by the number of sessions you can have. For example, the free tier for Gemini 2.5 Flash Live includes 3 sessions. [2]

For the paid tier, pricing is based on the amount of data processed (input and output), not the duration of the session. [3]

I hope this helps!
