Today we’re introducing GDPval, a new evaluation that measures AI on real-world, economically valuable tasks.
Evals ground progress in evidence instead of speculation and help track how AI improves at the kind of work that matters most. openai.com/index/gdpval-v0
GDPval spans 44 occupations selected from the top 9 sectors contributing to U.S. Gross Domestic Product (GDP).

Today we’re releasing research with @apolloaievals.
In controlled tests, we found behaviors consistent with scheming in frontier models—and tested a way to reduce it.
While we believe these behaviors aren’t causing serious harm today, this is a future risk we’re preparing for. openai.com/index/detectin…
Scheming = when an AI behaves one way on the surface while hiding its true goals.
Today’s deployed systems have little opportunity to scheme in ways that could cause serious harm. The most common failures are simple deceptions—like pretending to complete a task without doing it. We’ve studied and mitigated these issues and made meaningful improvements in GPT-5 over earlier models.
But as AIs take on more complex, long-term tasks with real-world impact, the potential for harmful scheming will grow—so our safeguards and testing must grow with it.

We released two open-weight reasoning models—gpt-oss-120b and gpt-oss-20b—under an Apache 2.0 license.
Developed with open-source community feedback, these models deliver meaningful advancements in both reasoning capabilities & safety.
openai.com/index/introduc…
gpt-oss-120b matches OpenAI o4-mini on core benchmarks and exceeds it in narrow domains like competitive math or health-related questions, all while fitting on a single 80GB GPU (or high-end laptop).
gpt-oss-20b fits on devices as small as 16GB, while matching or exceeding OpenAI o3-mini.

ChatGPT can now do work for you using its own computer.
Introducing ChatGPT agent—a unified agentic system combining Operator’s action-taking remote browser, deep research’s web synthesis, and ChatGPT’s conversational strengths.
ChatGPT agent starts rolling out today to Pro, Plus, and Team users.
Pro users will get access by the end of day, while Plus and Team users will get access over the next few days.
We're excited to announce we’ve launched several improvements to ChatGPT search, and today we’re starting to roll out a better shopping experience.
Search has become one of our most popular & fastest growing features, with over 1 billion web searches just in the past week 🧵
Shopping
We’re experimenting with making shopping simpler and faster to find, compare, and buy products in ChatGPT.
✅ Improved product results
✅ Visual product details, pricing, and reviews
✅ Direct links to buy
Product results are chosen independently and are not ads.
These shopping improvements are starting to roll out today to Plus, Pro, Free, and logged-out users everywhere ChatGPT is available. It will take a few days to complete the rollout.

Introducing OpenAI o3 and o4-mini—our smartest and most capable models to date.
For the first time, our reasoning models can agentically use and combine every tool within ChatGPT, including web search, Python, image analysis, file interpretation, and image generation.
OpenAI o3 is a powerful model across multiple domains, setting a new standard for coding, math, science, and visual reasoning tasks.
o4-mini is a remarkably smart model for its speed and cost-efficiency. This allows it to support significantly higher usage limits than o3, making it a strong high-volume, high-throughput option for everyone with questions that benefit from reasoning. openai.com/index/introduc…

Starting today, memory in ChatGPT can now reference all of your past chats to provide more personalized responses, drawing on your preferences and interests to make it even more helpful for writing, getting advice, learning, and beyond.
In addition to the saved memories that were there before, it can now reference your past chats to deliver responses that feel noticeably more relevant and useful.
New conversations naturally build upon what it already knows about you, making interactions feel smoother and uniquely tailored to you.

Today, we shared evals for an early version of the next model in our o-model reasoning series: OpenAI o3
On several of the most challenging frontier evals, OpenAI o3 sets new milestones for what’s possible in coding, math, and scientific reasoning.
It also makes significant progress on the ARC-AGI evaluation for the first time.
ChatGPT can now work directly with more coding and note-taking apps—through voice or text—on macOS.
Work with your code in context with expanded support for coding apps like Warp, IntelliJ IDEA, PyCharm, and more.

OpenAI o1 is now out of preview in ChatGPT.
What’s changed since the preview? A faster, more powerful reasoning model that’s better at coding, math & writing.
o1 now also supports image uploads, allowing it to apply reasoning to visuals for more detailed & useful responses.
OpenAI o1 is more concise in its thinking, resulting in faster response times than o1-preview.
Our testing shows that o1 outperforms o1-preview, reducing major errors on difficult real-world questions by 34%.
