Fixed a bug in image encoding that degraded image understanding in GPT-6 Sol and GPT-6 Luna. This update improves results on visual tasks in the API and Codex, including computer use. If your use cases involve image inputs, we recommend rerunning your evaluations and retrying workflows affected by the issue.
公式の更新履歴を見る ↗Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS generally available (GA): Released our next-generation text-to-speech (TTS) audio models and the Gemini API Voices endpoint (/v1beta/voices): Gemini 3.8 Flash TTS (gemini-3.8-flash-tts): Flagship creative TTS model engineered for studio-grade voice fidelity, nuanced acting, regional dialects, and long-form multi-turn stability. Gemini 3.8 Flash-Lite TTS (gemini-3.8-flash-lite-tts): Fast, cost-efficient TTS model built to replace gemini-3.1-flash-tts-preview for high-throughput production and real-time voice agent cascades. Voice design, Voice replication, and the Extended Voice Library: Create persistent custom vocal personas from text prompts, replicate voices with consent verification, and query 150+ prebuilt and custom voices. See the Text-to-speech guide to get started.
公式の更新履歴を見る ↗Released GPT-6 Sol (gpt-6-sol) and GPT-6 Luna (gpt-6-luna). These reasoning models accept text and image inputs and generate text through the Responses and Chat Completions APIs. Standard pricing per 1M tokens for prompts with up to 272K input tokens: GPT-6 Sol: $2 input, $0.20 cached input, and $10 output. GPT-6 Luna: $0.10 input, $0.01 cached input, and $0.50 output. Compare capabilities in the model catalog, and see pricing for cache writes, longer prompts, and other processing tiers.
公式の更新履歴を見る ↗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.
公式の更新履歴を見る ↗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.
公式の更新履歴を見る ↗Added API key creation governance controls at the organization and project levels. Administrators can allow only service-account keys, allow only user-owned project keys, or disable all new API key creation. Organization restrictions take precedence over project settings, and existing API keys are unaffected. See production best practices for details.
公式の更新履歴を見る ↗Gemini 3.8 Live and Gemini 3.8 Live Extended Thinking generally available (GA): Released two new audio-to-audio models for real-time voice applications using the Live API: Gemini 3.8 Live (gemini-3.8-live): The default option for most low-latency voice agent experiences and real-time dialogue without reasoning delays. Features interleaved reasoning, default asynchronous function calling, and full session client content updates. Gemini 3.8 Live Extended Thinking (gemini-3.8-live-extended-thinking): High-reasoning audio-to-audio model supporting background reasoning during live audio interactions, recommended when higher background reasoning is required. To get started, see the Live API guide, the Capabilities guide, and the Thinking guide.
公式の更新履歴を見る ↗Released the Agents API in public beta. Build agents with a managed Codex harness while OpenAI handles session orchestration, context compaction, and recovery. Use durable sessions to continue work across turns, stream progress, and connect your own tools and MCP servers. Run agents in OpenAI-hosted sandboxes or connect a sandbox from your own infrastructure or a supported provider. Start with the Agents API quickstart.
公式の更新履歴を見る ↗You can now set expiration dates when creating project API keys. Administrators can also enforce a maximum key lifetime at the organization or project level in Platform settings, requiring newly created keys to expire within the configured limit. See production best practices for guidance on key expiration and rotation.
公式の更新履歴を見る ↗GPT-Live-1 is now generally available in the API. Build full-duplex voice conversations that can continue while a backend model or agent handles reasoning and tools. Use Responses delegation with an OpenAI model, or client delegation to connect your own backend. Voice sessions cost $0.05 per minute, billed per second; backend model and tool usage is charged separately. Start with GPT-Live, prompting, and migration guidance. See pricing for details.

公式の更新履歴を見る ↗Released GPT Image 2.5 Sunburst and GPT Image 2.5 Flare for image generation and editing through the Image API and the Responses API image generation tool. Use Sunburst for workflows where editing precision matters most, or Flare for fast, high-quality everyday image generation. Both models support the new xhigh and max quality settings and use GPT Image 2 token rates. See the image generation guide and pricing.
