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.
Released GPT-6.1 Terra, a fast, efficient model for visual reasoning, precise computer use, and clear, natural writing. See the GPT-6 guide for prompting and migration guidance.
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.
Added scheduled automations to the Agents API public beta. Schedule one-time or recurring tasks in new or existing sessions. Enable the automations tool to let an agent schedule its own follow-ups in the current session.
The Decisions API is now generally available with gpt-6-luna. Cache shared input across requests for prompt-cache discounts, include images in individual question instructions, and pass structured data directly with input_json. Each request now supports up to 400 questions, increased from 200 in public beta. Review the changes since public beta.
You can now choose which service tiers projects can use in Platform settings. Organization settings can restrict service tiers for all projects. See service tier errors.
You can now choose 12-hour prompt caching in the API. 12-hour prompt caching keeps shared instructions, tools, and context cached longer to benefit from lower cached-input pricing, even when requests are hours apart. 12-hour cache writes cost 2.5x the input token price. Read more here.
OpenAI-hosted sandboxes in the Agents API now include the Artifact SDK and skills for creating and editing spreadsheets, presentations, and Word documents. Added Ultrafast mode to the Agents API. Set agent.service_tier to ultrafast with a supported model to reduce the time between generated tokens.
Released prompt-to-voice for all API customers. Create a custom voice from a text description through the API or voice Playground, then reuse it in GPT-Live sessions. Creating a prompt-generated voice is free; speech generation uses regular GPT-Live session billing. Added nine natural voices for GPT-Live: Nuri, Juni, and Flitz (German); Brise and Sillage (French); Nira (Hindi); Harema and Shida (Japanese); and Noeul (Korean).
Added native Decisions integration in GPT-Live. Your app can act while your user is speaking or react to what Live says. Let Live call Decisions directly through native delegation, or trigger decisions as input or output transcript deltas arrive.
Gemini 4 Argon (gemini-4-argon) generally available (GA): Released Gemini 4 Argon (gemini-4-argon), our most capable model built for complex coding, agentic, math, and science tasks. For API changes, pricing, and migration guidance, see What's new in Gemini 4 Argon.
