Gemini Robotics-ER 1.6

Preview

Embodied-reasoning vision-language model for robotics (spatial understanding, pointing, trajectory planning) - a specialist, not a general chat model. Preview. Inputs text/image/video/audio, output text; 131,072 input / 65,536 output tokens. $1.00/M in and $5.00/M out standard, $0.50/$2.50 batch. Supports function calling, structured output, thinking and caching, but no separate cached-input rate is published. Release date April 14, 2026 read first-party 2026-08-05 from the Release date column of Google's deprecations table (supersedes an earlier note reading the model page's 'spec table latest update December 2025' as not-a-release-date and leaving released null - the table states the real one as data). Shutdown date August 31, 2026 read first-party from Google's deprecations table 2026-07-31; Google states no lifecycle status for it, so status stays preview. Its recommended replacement there is gemini-robotics-er-2-preview, added to the catalog 2026-08-02 and now pointed at from this row; Google also offers gemini-robotics-er-2-streaming-preview as an upgrade path for Live API users.

Gemini Robotics-ER 1.6 by Google costs $1 per 1M input tokens and $5 per 1M output tokens ($2/1M blended), with a 131K (131.072-token) context window. It is scheduled for retirement, shutting down 31 Aug 2026; the recommended replacement is Gemini Robotics-ER 2.
