Gemini Robotics-ER 2 Streaming

Preview

The streaming sibling of gemini-robotics-er-2-preview, shipped in the same 2026-07-30 public-preview launch: optimized for real-time text streaming over the Live API, for low-latency robot agents processing continuous bidirectional audio and video input, with function calling. Same headline rates as the non-streaming endpoint ($2.00/M in, $10.00/M out, paid tier) and the same 131,072 / 65,536 token limits, inputs text/images/video/audio, output text. Its pricing block publishes NO context-caching rate (the non-streaming endpoint publishes $0.20/1M) and no batch tier, so price_cached_input_per_mtok is null — that is an absence on Google's own pricing page, not an unread value. No knowledge cutoff, no release-lifecycle status and no shutdown date are published for it.

Gemini Robotics-ER 2 Streaming by Google costs $2 per 1M input tokens and $10 per 1M output tokens ($4/1M blended), with a 131K (131.072-token) context window. It is in preview.
