●ROBOTICS — The ER 1.6 preview that shut down on August 31 does have a successor. Gemini Robotics ER 2 is in public preview, in both standard and streaming variants●VIDEO — ER 2 judges success and failure from live video rather than still snapshots, which is what lets it catch spills, slips, and misalignments while a task is still running●DEADLINE — Next up is September 30, when gemini-omni-flash-preview is retired.
