Gemini API deprecates Gemini 3.7 Flash and 3.5 Flash, routing requests to newer 3.8 Flash and 3.6 Flash models in Google AI Studio and the API. It also deprecates the deep-research-pro-preview-12-2025 agent and points users to newer Deep Research versions.
Gemini 3.7 Flash deprecation

gemini-3.7-flash is deprecated and has been replaced by gemini-3.8-flash. It is no longer available to select in Google AI Studio, and API requests to gemini-3.7-flash are automatically routed to gemini-3.8-flash. Update your model string to gemini-3.8-flash and review the Gemini 3.8 Flash guide.

Gemini 3.5 Flash deprecation

gemini-3.5-flash is deprecated and has been replaced by gemini-3.6-flash. It is no longer available to select in Google AI Studio, and API requests to gemini-3.5-flash are automatically routed to gemini-3.6-flash. Update your model string to gemini-3.6-flash (or gemini-3.8-flash) and review the Gemini 3.6 Flash guide.

Deep Research Agent deep-research-pro-preview-12-2025 deprecation

The deep-research-pro-preview-12-2025 agent is deprecated and will be shut down on October 23, 2026.

Migrate your requests to one of the newer Deep Research agent versions:

deep-research-preview-04-2026: Designed for speed and efficiency, ideal to be streamed back to a client UI.

deep-research-max-preview-04-2026: Maximum comprehensiveness for automated context gathering and synthesis.

To migrate, update the agent parameter in your interactions.create requests from deep-research-pro-preview-12-2025 to deep-research-preview-04-2026 (or deep-research-max-preview-04-2026).

Gemini API limits 2.5 model access to active users while keeping legacy support and steering new projects to newer models.
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.

Gemini API notes the Antigravity Agent 09-2026 release, which replaces the May preview and updates local tool parameters, file editing, reading, and search. The older preview shuts down October 5, 2026.

Antigravity Agent 09-2026

Released antigravity-preview-09-2026, which replaces and deprecates antigravity-preview-05-2026.

If you run on a remote sandbox (environment: "remote") and read only output_text or model_output steps, update the agent string and nothing else changes.

If you run tools locally (local_environment) or parse function_call steps, the built-in tools changed. Parameters use PascalCase instead of snake_case, and file edits use line-range replacements instead of full rewrites.
Capability 05-2026 09-2026 File creation write_file(path, content) write_to_file(TargetFile, CodeContent, Overwrite, Description) File editing write_file(path, content), full rewrite replace_file_content(TargetFile, StartLine, EndLine, TargetContent, ReplacementContent) File reading read_file(path, offset, limit), byte offsets view_file(AbsolutePath, StartLine, EndLine, ContentOffset) Directory listing list_files(path) list_dir(DirectoryPath) File and code search None, agents used shell commands find_by_name(SearchDirectory, Pattern, MaxDepth) and grep_search(SearchPath, Query, IsRegex) Shell execution code_execution(command, timeout_seconds) Unchanged Web search google_search(queries) Unchanged
See the Antigravity Agent guide. antigravity-preview-05-2026 shuts down on October 5, 2026, tracked on the deprecations page.
