* **Gemini Embedding 2 Preview deprecation**: [`gemini-embedding-2-preview`](/docs/models/gemini-embedding-2-preview) is [deprecated](/docs/deprecations#embedding-deprecated-models). Effective November 6, 2026, API requests to `gemini-embedding-2-preview` route to [`gemini-embedding-2`](/docs/models/gemini-embedding-2) at [Gemini Embedding 2 rates](/docs/pricing#gemini-embedding-2). Update your model string to `gemini-embedding-2`. `gemini-embedding-2` uses the same API schema, pricing, and embedding space, so no other code changes or vector re-indexing are needed.
* **Gemini Omni 1.2 Flash generally available (GA)**: Released [Gemini Omni 1.2 Flash](/docs/models/gemini-omni-flash) (`gemini-omni-1.2-flash`), featuring up to 15-second video generation and conversational editing (3 to 10 seconds for first and last frame interpolation, and 3 to 10 seconds per-turn video extension up to 30 seconds total length), improved character and subject consistency across up to 6 reference images, 30% lower video output [pricing](/docs/pricing#gemini-omni-1.2-flash) ($12.00 per 1M tokens), and doubled paid-tier [rate limits](/docs/rate-limits#gemini-omni-flash-rate-limits). See the [Gemini Omni Flash guide](/docs/omni) to get started. * **Gemini Omni 1.1 Flash automatic routing notice**: Effective **December 3, 2026**, API requests to `gemini-omni-1.1-flash` will automatically route to `gemini-omni-1.2-flash` at [Gemini Omni 1.2 Flash rates](/docs/pricing#gemini-omni-1.2-flash). * **Expanded Office and OpenDocument file support**: The Gemini API now accepts PowerPoint 97-2003 (PPT), OpenDocument Presentation (ODP), and OpenDocument Spreadsheet (ODS) files as input, and adds page-image processing for Word 97-2003 (DOC) files. DOC, PPT, and ODP files are rendered as page images. For ODS files, the model receives the data and formulas from the first sheet. Processing for DOCX, DOTX, ODT, PPTX, XLSX, and XLS files is unchanged. See [Office and OpenDocument files](/docs/document-processing#office-documents) for how each format is processed. * **More file types and file URIs in function responses**: Tools can now return Office and OpenDocument files, audio, and video to the model. * **GenerateContent API**: Function response parts now accept audio, video, and Office and OpenDocument files, in addition to images, PDFs, and plain text. They also accept `fileData`, so tools can return a Files API URI instead of inline bytes. `displayName` is now available on both `inlineData` and `fileData`, and video parts accept `mediaProcessing` (`STATIC` or `AGENTIC`). * **Interactions API**: `function_result` steps now accept `document`, `audio`, and `video` content blocks, in addition to `text` and `image`, by inline `data` or `uri`. Video blocks are available in `v1beta` and `v1alpha` and accept `processing`. See [Multimodal function responses](/docs/function-calling#multimodal) for details.
* **Voice remixing for Gemini 3.8 TTS**: Released [Voice remixing](/docs/voice-remixing), which lets you modify an existing prebuilt or [designed](/docs/voice-design) voice using natural-language instructions to create a new, independent stored voice. Use `POST /v1beta/voices` with `gemini-3.8-flash-tts` (or remix interactively in [Google AI Studio](https://aistudio.google.com/generate-speech)) to generate a `voice_...` ID, then synthesize speech with [Gemini 3.8 Flash TTS](/docs/models/gemini-3.8-flash-tts) or [Gemini 3.8 Flash-Lite TTS](/docs/models/gemini-3.8-flash-lite-tts). See the [Voice remixing guide](/docs/voice-remixing) to get started.

Before December 1, 2026, update your model string to `gemini-3.8-flash` and review the [Gemini 3.8 Flash migration guide](/docs/whats-new-gemini-3.8#migrate-to-gemini-3-8-flash). Breaking API changes include function calling and `thought_signature` validation, `thinking_level` replacing `thinking_budget`, and removed sampling parameters and prefilled model turns. * **Gemini 2.5 Flash deprecation**: [`gemini-2.5-flash`](/docs/models/gemini-2.5-flash) is [deprecated](/docs/deprecations#gemini-2.5-flash-models) and is no longer available to select in Google AI Studio. Effective December 1, 2026, all API requests to `gemini-2.5-flash` will automatically route to [`gemini-3.5-flash-lite`](/docs/models/gemini-3.5-flash-lite) and be billed at [Gemini 3.5 Flash-Lite rates](/docs/pricing#gemini-3.5-flash-lite). Before December 1, 2026, update your model string to `gemini-3.5-flash-lite` and review the [Gemini 3.5 Flash-Lite migration guide](/docs/whats-new-gemini-3.6#migrate-to-gemini-3-5-flash-lite). Breaking API changes include function calling and `thought_signature` validation, `thinking_level` replacing `thinking_budget`, and removed sampling parameters and prefilled model turns.
Gemini API CLI (gemini-api) beta: Released the Gemini API CLI (gemini-api), a stateless, zero-dependency command-line client for AI coding agents, scripts, and CI pipelines. Use gemini-api on the Interactions API to generate text and media, analyze files, and run Gemini managed agents. See the Gemini API CLI guide to get started.
Generate Content API storage on by default: New projects using the Generate Content API (generateContent, streamGenerateContent, and batchGenerateContent) on the paid tier now store requests by default (store=true), matching the Interactions API. Existing projects keep their current setting. To opt out, set store=false on individual requests or turn off Generate Content API logging in the Settings panel of the Logs and Datasets dashboard. See Logs and datasets for details.

See the Text-to-speech guide to get started.
Gemini 2.5 models access update: To ensure reliable performance for everyone, we are limiting access to the 2.5 models to users who have actively used them in the past. These models are not deprecated and will continue to be served until further notice through the API. For any new projects, use our latest models: 3.5 Flash-Lite or 3.8 Flash. This helps us maintain sufficient capacity for both ongoing legacy workflows and new applications.
