Gemini Robotics-ER 1.5

Retired

Embodied-reasoning vision-language model for robotics, originally superseded by gemini-robotics-er-1.6-preview. REPLACEMENT RE-POINTED 2026-10-20: the deprecations table now names gemini-robotics-er-2-preview as the recommended replacement, in the same edit that greyed the gemini-robotics-er-1.6-preview row as shut down; until the 2026-10-19 read it named gemini-robotics-er-1.6-preview. Google does not date the edit (page: Last updated 2026-10-20 UTC). Google marks already-shut-down models with a gray row on the deprecations table ("Already-shutdown models are indicated with gray backgrounds"), and this row is gray, so status is retired. Google states the listed shutdown dates are "the earliest possible dates on which a model might be retired". Not priced on the current pricing page, so token prices are null rather than guessed from the surviving family member. Google's current models page publishes no input/output token limits for this endpoint (read 2026-08-19), so context_window and max_output_tokens are null rather than carried over from a page that no longer states them. Lifecycle read first-party from Google's deprecations table on 2026-08-19.
