Two new additions to the API:

📚 Deep research
🪝 Webhooks
o3-deep-research: platform.openai.com/docs/models/o3…
o4-mini-deep-research: platform.openai.com/docs/models/o4…

These models are the same post-trained o3 and o4-mini models that power deep research in ChatGPT.

They also support MCP (search/fetch) and Code Interpreter.
And instead of polling, webhooks now let you receive notifications for certain API events—such as completed responses, fine-tuning jobs, and batch jobs.

We recommend using webhooks for long-horizon tasks (like deep research!) to improve reliability.

🇵 🇷 🇴 🇲 🇵 🇹 🇸 are an API primitive now!

Centrally manage, version, and optimize prompts. Use (and reuse!) prompts across the Playground, API, Evals, and Stored Completions.
🆕 The Prompt object is a new resource that can be referenced in the Responses API and our SDKs. Prompts can be preconfigured too—including tools, models, and messages. No more manual copying and pasting!
And in the Playground:

⚡️️We’ve improved the “Generate” button. Now, hit “Optimize”, and your prompt will be even better optimized for the API.
🔡 Replacing “presets”, you can now save Prompts—including its versions and configurations—and reuse or share them.

Evals now supports tool use. 🛠️

You can now use tools and Structured Outputs when completing eval runs, and evaluate tool calls based on the arguments passed and responses returned. This supports tools that are OpenAI-hosted, MCP, and non-hosted. Read more in our guides below.

We’re rolling out a few updates to Codex today:

1. Codex is rolling out to ChatGPT Plus users today. It includes generous usage limits for a limited time, but during periods of high demand, we might set rate limits for Plus users so that Codex remains widely available.
2. Next, our top requested feature: You can now give Codex access to the internet during task execution to install base dependencies, run tests that need external resources, upgrade or install packages needed to build new features, and more.
3. Internet access is off by default, and can be enabled when creating a new environment or by editing an existing one. You have full control over the domains and HTTP methods Codex can use during task execution. Learn more about usage and risks in the docs: platform.openai.com/docs/codex/age…Image

🆕 Four updates to building agents with OpenAI: Agents SDK in TypeScript, a new RealtimeAgent feature for voice agents, Traces support for the Realtime API, and improvements to our speech-to-speech model.
The Agents SDK is now available in TypeScript and supports handoffs, guardrails, tracing, MCP, and other core agent primitives, just like the Python version.

openai.github.io/openai-agents-…Image
It includes new support for human-in-the-loop approvals, allowing you to pause tool execution, serialize and store the agent state, approve or reject specific calls, and resume the agent run.

Image gen is now available in the API!

We’re launching gpt-image-1, making ChatGPT’s powerful image generation capabilities available to developers worldwide starting today.

✅ More accurate, high fidelity images
🎨 Diverse visual styles
✏️ Precise image editing
🌎 Rich world knowledge
🔤 Consistent text rendering

Check out the guide to start building: platform.openai.com/docs/guides/im…Image
You can also use gpt-image-1 in the Playground to quickly iterate on prompts and images: platform.openai.com/playground/ima…
We’ve been collaborating closely with developers to understand where image gen can be most useful in the real world. Here are some examples from early adopters across domains like creative tools, consumer apps, enterprise software, and more below. 👇

We're launching new tools to help developers build reliable and powerful AI agents. 🤖🔧

Timestamps:
01:54 Web search
02:41 File search
03:22 Computer use
04:07 Responses API
10:17 Agents SDK
Our new API primitive: the Responses API. Combining the simplicity of Chat Completions with the tool-use of Assistants, this new foundation provides more flexibility in building agents. Web search, file search, or computer use are a couple lines of code!

platform.openai.com/docs/quickstar…
🔎 Web search—integrate with a few lines of code and your agent can get up-to-date answers from the web (with citations).
