An application security agent that helps you secure your codebase by finding vulnerabilities, validating them, and proposing fixes you can review and patch. Now, teams can focus on the vulnerabilities that matter and ship code faster.

ChatGPT for Excel builds full spreadsheets from plain language, analyzes data across tabs and formulas, and updates your workbook in real time. It explains every change, links answers to the cells it touches, and asks before editing. Fix errors, spot patterns, and turn raw data into insights without switching tools. Same Excel. Smarter workflows.

GPT-5.4 Thinking delivers deeper web research, stronger context retention on long tasks, and 33% fewer factual errors than its predecessor. You can now interrupt the model mid-response and redirect it. No need to start over. Same intelligence. More control. Less token burn by default.

Every agent turn, you're resending the full context. Again. That overhead compounds fast. WebSocket Mode for the Responses API keeps a persistent connection, sends only incremental inputs, and cuts end-to-end latency by up to 40% on heavy tool-call workflows.

A new platform that helps enterprises build, deploy, and manage AI agents that can do real work. Frontier gives agents the same skills people need to succeed at work: shared context, onboarding, hands-on learning with feedback, and clear permissions and boundaries. That’s how teams move beyond isolated use cases to AI coworkers that work across the business.

Introducing Prism, a free workspace for scientists to write and collaborate on research, powered by GPT-5.2.

FrontierScience is a new benchmark for evaluating AI’s expert-level scientific reasoning across physics, chemistry, and biology. It measures both Olympiad-style problem solving and real research tasks, helping track how well advanced models can support and accelerate scientific work.

ChatGPT Images is powered by the new GPT Image 1.5 model. It delivers precise edits that preserve lighting and facial likeness, stronger instruction following, and 4x faster generation. Available now in ChatGPT and via API.

GPT‑5.2 is designed to unlock even more economic value for people; it’s better at creating spreadsheets, building presentations, writing code, perceiving images, understanding long contexts, using tools, and handling complex, multi-step projects.

Group chats are now in ChatGPT. You can add friends, family, or coworkers to a shared conversation to collaborate, plan, and create together with AI. It's separate from your private chats.

GPT-5.1 Instant and Thinking are trained using the same stack as OpenAI's reasoning models, so they score higher on factuality and complex problem-solving than GPT-5, while also introducing a more natural, conversational tone. We think many people will find that GPT-5.1 does a better job of bringing IQ and EQ together, but one default clearly can’t meet everyone’s needs.

gpt-oss-safeguard is a new family of open-source safety models (120b & 20b) from OpenAI. They use reasoning to classify content based on a custom, developer-provided policy at inference time, providing an explainable chain-of-thought for each decision.

With Atlas, ChatGPT can come with you anywhere across the web—helping you in the window right where you are, understanding what you’re trying to do, and completing tasks for you, all without copying and pasting or leaving the page.

Apps are now in ChatGPT. Chat directly with interactive apps from Spotify, Canva, Zillow, and more, right in your conversation. Built on the new open Apps SDK, it’s a new generation of apps that turns ChatGPT into the next major app platform.

ChatGPT now lets you buy products directly in chat. Powered by the new open Agentic Commerce Protocol (ACP) built with Stripe, Instant Checkout connects you with merchants like Etsy (and soon Shopify) to turn product discovery into a seamless purchase.

It is a new feature for Pro mobile users that gives you daily updates made just for you. It learns from your chats, feedback, and connected apps to share useful cards each day, so you can stay informed and reach your goals faster.

Codex just got faster, more reliable, and better at real-time collaboration and tackling tasks independently anywhere you develop—whether via the terminal, IDE, web, or even your phone.

gpt-realtime is OpenAI's new speech-to-speech model for production voice agents, delivering low latency and natural, expressive speech. The Realtime API is now GA, adding key features for developers like remote MCP support, image input, and SIP phone calling.

AGENTS.md is a simple, open format for guiding coding agents, used by over 20k open-source projects. Think of it as a README for agents.

With major improvements in reasoning, code quality, and UX. It handles complex coding tasks with minimal prompting, provides clear explanations, and introduces enhanced agentic capabilities, making it a powerful collaborator and intelligent assistant for all.
