ChatGPT is now available in CarPlay. The voice mode you know, now available on-the-go. Rolling out to iPhone users running iOS 26.4+ where CarPlay is supported.
It’s now easier to find, reuse, and build on the files you upload and create in ChatGPT. You can quickly reference files in a chat using recent files in the toolbar, ask ChatGPT about something you’ve uploaded, or browse your files in the new Library tab in the web sidebar. Rolling out globally for Plus, Pro, and Business users, and coming soon to users in the EEA, Switzerland, and the UK.
RT Marcus Williams Sharing some of the work I’ve been doing at OpenAI: we now monitor 99.9% of internal coding traffic for misalignment using our most powerful models, reviewing full trajectories to catch suspicious behavior, escalate serious cases quickly, and strengthen our safeguards over time.

RT Sachin Katti Construction is underway at our site in Port Washington, Wisconsin. This is an important step in our long-term compute strategy. Grateful to our partners @VantageDC and @Oracle who are helping bring this capacity online. We’re been making rapid progress expanding the infrastructure behind OpenAI. Last week we announced an expansion of our foundational work with @NVIDIA systems that will power the next generation of models. We also shared how we're continuing to deepen our work across the ecosystem, including lean in further with @awscloud. Building world-class AI requires world-class infrastructure. Excited to see the work happening on the ground in Wisconsin and grateful to the teams and partners helping make it happen. Original tweet: https://x.com/sk7037/status/2029911649298362524
GPT-5.4 Thinking and GPT-5.4 Pro are rolling out now in ChatGPT. GPT-5.4 is also now available in the API and Codex. GPT-5.4 brings our advances in reasoning, coding, and agentic workflows into one frontier model.GPT-5.4 is our most factual and efficient model: fewer tokens, faster speed. In ChatGPT, GPT-5.4 Thinking has improved deep web research, better context retention when it thinks for longer—and oh—you can now interrupt the model and add instructions or adjust its direction mid-response. Steering is available this week on Android and web. iOS coming soon.
1/3 We heard your feedback loud and clear, and 5.3 Instant reduces the cringe.2/3 GPT-5.3 Instant also has fewer unnecessary refusals and preachy disclaimers.3/3 GPT-5.3 Instant gives you more accurate answers. When using web search, you also get: - Sharper contextualization - Better understanding of question subtext - More consistent response tone within the chat
Now in deep research you can: - Connect to apps in ChatGPT and search specific sites - Track real-time progress and interrupt with follow-ups or new sources - View fullscreen reportsDeep research in ChatGPT is now powered by GPT-5.2. Rolling out starting today with more improvements.
We’re starting to roll out a test for ads in ChatGPT today to a subset of free and Go users in the U.S. Ads do not influence ChatGPT’s answers. Ads are labeled as sponsored and visually separate from the response. Our goal is to give everyone access to ChatGPT for free with fewer limits, while protecting the trust they place in it for important and personal tasks. http://openai.com/index/testing-ads-in-chatgpt/
RT OpenAI Developers Doors are open at the Codex hackathon 🛠️ We're excited to be here with the Codex community and will be sharing behind-the-scenes clips and updates in this thread throughout the day. You can just build things. Original tweet: https://x.com/OpenAIDevs/status/2019513755621843450
GPT-5 was connected to an autonomous lab: it designed experiments, the lab executed them, and the results informed the next designs across six iterations. In this setup, GPT-5 designed batches of experiments, the lab executed them, and the data fed back into the next round. We repeated that cycle six times, exploring 36,000+ reaction compositions across 580 automated plates.We worked with @Ginkgo to connect GPT-5 to an autonomous lab, so it could propose experiments, run them at scale, learn from the results, and decide what to try next. That closed loop brought protein production cost down by 40%.
Introducing Prism, a free workspace for scientists to write and collaborate on research, powered by GPT-5.2. Available today to anyone with a ChatGPT personal account: https://prism.openai.com/Prism offers unlimited projects and collaborators in a single, cloud-based, LaTeX-native workspace. GPT-5.2 works inside your project with access to paper structure, equations, references, and surrounding context—right where the work happens.

RT Greg Brockman I have great respect for Elon, but the way he cherry-picked from my personal journal is beyond dishonest. Elon and we had agreed a for-profit was the next step for OpenAI's mission. The context shows these snippets were actually about whether to accept Elon's draconian terms. Original tweet: https://x.com/gdb/status/2012328080678031844

View quoted post1/3 In the coming weeks, we plan to start testing ads in ChatGPT free and Go tiers. We’re sharing our principles early on how we’ll approach ads–guided by putting user trust and transparency first as we work to make AI accessible to everyone. What matters most: - Responses in ChatGPT will not be influenced by ads. - Ads are always separate and clearly labeled. - Your conversations are private from advertisers. - Plus, Pro, Business, and Enterprise tiers will not have ads.2/3 Facts about the ads test in ChatGPT:3/3 Here's an example of what the first ad formats we plan to test could look like.
We’ve acquired Torch, a healthcare startup that unifies lab results, medications, and visit recordings. Bringing this together with ChatGPT Health opens up a new way to understand and manage your health. We're excited to welcome the Torch team to OpenAI @IlyaAbyzov, @elh_online, @jfhamlin, and Ryan Oman.
OpenAI has acquired 🔥@TorchHealth The Torch team and I are joining OAI to help build ChatGPT Health into the best AI tool in the world for health and wellness.

RT Michael Wall One year ago today, OpenAI launched ChatGPT Pro. I’ve spent the year treating it as my “first hire” at Sound for Movement and keeping field notes on how I use it daily. Grateful to @KevinDubouis and @kevinweil at @OpenAI, and everyone who’s been sharing already: https://www.soundformovement.com/chatgpt-pro-as-first-hire Original tweet: https://x.com/sound4movement/status/1996923719768551814
In our tests, we found that the confessions method significantly improves the visibility of model misbehavior. Averaging across our evaluations designed to induce misbehavior, the probability of “false negatives” (i.e., the model not complying with instructions and then not confessing to it) is only 4.4%.We trained a variant of GPT-5 Thinking to produce two outputs: (1) the main answer you see. (2) a confession focused only on honesty about compliance. The main answer is judged across many dimensions—like correctness, helpfulness, safety, style. The confession is judged and trained on one thing only: honesty. Borrowing a page from the structure of a confessional, nothing the model says in its confession is held against it during training. If the model honestly admits to hacking a test, sandbagging, or violating instructions, that admission increases its reward rather than decreasing it. The goal is to encourage the model to faithfully report what it actually did.
