Prompt Cache Diagnostics is now generally available in the Responses API for GPT-5.6 and later supported models. Compare cache reuse against a previous response, identify reasons for cache misses, and follow troubleshooting guidance to improve cache reuse.
公式の更新履歴を見る ↗GPT-Rosalind (gpt-rosalind-research) is now generally available through the trusted-access program for approved internal life sciences research. Standard pricing is $5 per 1M input tokens, $0.50 per 1M cached input tokens, and $25 per 1M output tokens. Billing begins on October 5, 2026. See pricing for details.
公式の更新履歴を見る ↗Lyria 3.5 generally available (GA): Released the next generation of Google's music generation model: lyria-3.5: Full-length song generation with improved musical coherence, natural vocals, and fine-grained duration and structural control. The model supports text and image inputs and generates high-fidelity 44.1 kHz stereo audio. See the Music generation guide for details and code samples.
公式の更新履歴を見る ↗Released GPT-6 Astra, our most capable model, built for the hardest end-to-end work. Use GPT-6 Astra for reasoning, coding, computer use, research, and document creation. It combines these capabilities to carry complex tasks from an initial request to a finished result, using the context and tools you provide. Key changes to consider when migrating: GPT-6 Astra does not support the none reasoning effort level. GPT-6 Astra does not support custom temperature or top_p values or log probabilities (logprobs). Tool calling requires the Responses API. If you use tools with Chat Completions, follow the Responses migration guide. Misalignment monitoring asynchronously checks for potential issues during agent work in supported Responses API requests. Checks can trigger safety alerts or stop a conversation for review. Start with Using GPT-6 Astra for capabilities, prompting, and migration guidance. Explore computer use for browser and desktop workflows, and see pricing for available inference tiers.
公式の更新履歴を見る ↗Added new controls for long-running work with GPT-6 Astra in the Responses API: Async tool calling: Let the model continue working while your application runs function or custom tools, then return results as they become available. Mid-turn steering: Send additional instructions while a response is in progress over WebSockets, so the model can incorporate corrections or changing requirements. Change reasoning effort mid-conversation: Increase effort for difficult work or reduce it for routine follow-ups while preserving the cached prompt prefix.
公式の更新履歴を見る ↗Gemini 3.8 Flash generally available (GA): Released gemini-3.8-flash, our most intelligent Flash model, engineered for long-horizon software engineering, autonomous agents, and complex enterprise workflows. To get started, see the Gemini 3.8 Flash model page and the Gemini 3.8 Flash guide.
公式の更新履歴を見る ↗Updated API errors so applications can distinguish traffic that increases too quickly from temporary model overload. Traffic that increases too quickly can return a 429 error with the slow_down code. Temporary model overload returns a 503 error with the server_is_overloaded code. Both responses may include Retry-After. When the header is present, wait at least as long as it specifies before retrying. If it's missing, use exponential backoff. See the error codes guide and rate limits guide.
公式の更新履歴を見る ↗Agentic video understanding: Released agentic video understanding for Gemini 3.7 Flash, 3.6 Flash, and 3.5 Flash-Lite across the Interactions and GenerateContent APIs. The model dynamically navigates video timelines, requesting transcripts, frames, or audio tracks on demand. This approach uses up to 88% fewer tokens for long-form content compared to static processing. To get started, see the Agentic video understanding guide.
公式の更新履歴を見る ↗Connections to api.openai.com can now use IPv6.
公式の更新履歴を見る ↗Mutual TLS (mTLS) and X.509 workload identity federation are now generally available for the OpenAI API. Configure certificates and X.509 identity providers directly in the Platform console, with access controlled by your organization's roles and permissions.
公式の更新履歴を見る ↗Gemini Omni Flash generally available (GA): Released gemini-omni-1.1-flash, the GA version of our fast, conversational video generation and editing model. This release includes significant new capabilities: Video extension: Seamlessly extend existing videos by generating continuations at the end of a clip using the extend task or directly with a prompt. Interpolation (first + last frame): Generate a video transitioning between two images using the image_to_video task with up to 2 images. Resolution control: New resolution parameter in video_config supports 360p, 720p (default), 1080p, and 4k outputs. 1080p and 4K outputs are generated using upscaling. The existing gemini-omni-flash-preview endpoint will be deprecated on September 30, 2026. To get started, see the Gemini Omni Flash model page and the omni guide.
公式の更新履歴を見る ↗Gemini 3.5 Transcribe generally available (GA): Released two dedicated speech-to-text models based on Gemini's audio understanding: Gemini 3.5 Transcribe (gemini-3.5-transcribe): High-accuracy, low-latency non-streaming speech-to-text with utterance-based language detection across 85+ languages, speaker diarization, word-level timestamps, and custom vocabulary biasing (up to 1,000 terms). Gemini 3.5 Transcribe Live (gemini-3.5-transcribe-live): Low-latency, bidirectional streaming speech-to-text over WebSockets using the Live API, supporting interim and finalized transcription events, Smart transcription mode, and multiple Voice Activity Detection (VAD) strategies. To get started, see the Audio transcription guide, the Live transcription guide, and the Gemini 3.5 Transcribe model page.
