●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. The target is gemini-omni-1.1-flash, GA since August 27, and there are now under four weeks left●APIKEY — Every remaining standard API key, restricted ones included, stops working during September. The replacement is an auth key bound to a Google Cloud service account●PRICE — Gemini 3.7 Flash keeps its introductory $0.75/$3.75 per 1M through December 31, then moves to $1.50/$7.50 on January 1, 2027. Any estimate crossing the year needs both figures●AUDIO — Gemini 3.5 Transcribe handles language detection across 85+ languages, speaker diarization, word-level timestamps, and custom vocabulary biasing of up to 1,000 terms●ROBOTICS — The ER 1.6 preview that shut down on August 31 does have a successor.

The Day the Knowledge Cutoff Moved Forward, the Stale Part Was My System Instruction

When a model's knowledge cutoff advances, the thing that goes stale is not the model — it is the dated assertions in your system instruction. Here is why only the lines written between the two cutoffs flip from helpful to contradictory, plus a working audit script and its measured results.

What language should your system instruction be in? Measuring three approaches when most prompts arrive in the user's language

Keep the system instruction in English, or translate it into the user's language? I measured input tokens per language with countTokens, then lined up output-language match and schema compliance to find where nine tokens is enough.
