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.
Typically, as models become smarter, their problems become easier to address—for example, smarter models hallucinate less and follow instructions more reliably.

However, AI scheming is different.

As we train models to get smarter and follow directions, they may either better internalize human goals or just get better at hiding their existing true goals.

The core of anti-scheming research is to distinguish between these two, which requires understanding the reasoning behind a model's behavior.Image

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.Image

These models are trained for agentic workflows—supporting function calling, web search, Python execution, configurable reasoning effort, and full raw chain-of-thought access. github.com/openai/gpt-oss

ChatGPT can now connect to more internal sources & pull in real-time context—keeping existing user-level permissions.

Connectors available in deep research for Plus & Pro users (excl. EEA, CH, UK) and Team, Enterprise & Edu users:

Outlook
Teams
Google Drive
Gmail
Linear
& more
Additional connectors available in ChatGPT for Team, Enterprise, and Edu users:

SharePoint
Dropbox
Box
Workspace admins can also now build custom deep research connectors using Model Context Protocol (MCP) in beta.

MCP lets you connect proprietary systems and other apps so your team can search, reason, and act on that knowledge alongside web results and pre-built connectors.

Available to Team, Enterprise, and Edu admins, and Pro users starting today.

We’re launching a research preview of Codex: a cloud-based software engineering agent that can work on many tasks in parallel.

Rolling out to Pro, Enterprise, and Team users in ChatGPT starting today.

chatgpt.com/codex
Codex independently navigates your codebase, implements and tests code changes, and proposes pull requests for you to review.

It’s powered by codex-1, a version of OpenAI o3 optimized for software engineering.

openai.com/index/introduc…
.@calvinfo uses Codex when he's on call to triage issues and prioritize bug fixes, to help him stay focused on product work.

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.
Search in WhatsApp

You can now send a WhatsApp message to 1-800-ChatGPT (+1-800-242-8478) to get up-to-date answers and live sports scores.

Accessible everywhere ChatGPT is available.
