Gemini Robotics-ER 2

Preview

Embodied-reasoning (Gemini Robotics Embodied Reasoning 2) vision-language endpoint for robotics — advanced spatial reasoning, agentic code execution, multi-step tool orchestration, video moment finding, progress classification and multi-robot coordination. A specialist, not a general chat model. Public preview. Released 2026-07-30 per Google's API changelog ('Gemini Robotics ER 2 in public preview'), which shipped this and gemini-robotics-er-2-streaming-preview together. Paid-tier standard rates: $2.00/M in (text/image/video/audio), $10.00/M out including thinking tokens, context caching $0.20/1M plus a $1.00 per 1M-tokens-per-hour storage fee with no schema field; batch $1.00/$5.00. Spec table: 131,072 input / 65,536 output tokens, inputs text/images/video/audio, output text. It is the stated replacement for gemini-robotics-er-1.6-preview, which Google shuts down 2026-08-31. Google publishes no knowledge cutoff for it (the ER 1.6 spec table lists January 2025; the ER 2 table carries no cutoff row at all), so the field is null rather than inherited from the sibling. No shutdown date announced, and Google states no lifecycle status beyond the 'Preview' version label, so status is preview and retires_on is null.

Gemini Robotics-ER 2 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.
