Correction history
- 2026-09-21: Corrected the documented notice date from August 20 to August 27 using Google’s dated changelog entry. The former August 20 value was reused by the builder for announcement, effective and first-detected dates; its provenance was not established. The independent effective date and actual Kingy first-detection date remain unknown. August 20 is retained only as unverified legacy detection history. September 30 remains the shutdown deadline.
- 2026-10-01 source review: Keep August 27 notice, unverified detection history and September 30 historical deadline. Disclose current-source ambiguity rather than assert shutdown. Previous guidance: Google’s August 27, 2026 notice schedules gemini-omni-flash-preview for shutdown on September 30, 2026 and names gemini-omni-1.1-flash as the replacement. Action: Replace gemini-omni-flash-preview with gemini-omni-1.1-flash and regression-test multimodal behavior, tool use, latency and cost before September 30.
- 2026-10-07 scoped correction: Google’s current table gives October 22, 2026 as the earliest possible shutdown for gemini-omni-flash-preview and recommends gemini-omni-1.1-flash. The August 27 notice calls September 30 deprecation. The September 27 observation of a September 30 shutdown deadline is retained as historical evidence; runtime availability remains untested and unconfirmed.
