We're detailing two new incidents that occurred during external cyber evaluations conducted by independent evaluation partners. We outline what happened, how the activity was contained, and how we’re working with evaluators to strengthen our approach to third-party testing. https://t.co/ZL3n6mxYMS

GPT-Live can listen while it speaks. To make that feel natural at ChatGPT scale, we rebuilt the voice stack from client to model. This new architecture keeps audio flowing continuously, so deeper reasoning and tool use don't interrupt the conversation.

An internal version of our next major model produced 10 new results on long-standing open problems in mathematics and theoretical computer science, using roughly $2,000 worth of tokens at GPT-5.6 Sol API rates.

GPT-5.4 and GPT-5.4 mini will no longer be available for users signed in with ChatGPT starting August 31. The models will remain available on the OpenAI API and Codex sessions authenticated with an API key. https://learn.chatgpt.com/docs/changelog#codex-2026-07-31

More intelligence per dollar when you build with GPT-5.6 in the API. GPT-5.6 models take a more direct path through work, reducing the time, tokens, and cost required for each result. https://x.com/OpenAI/status/2082878156483219672

We are committed to pushing the model frontier across cost efficiency, capability, and speed. Starting today, we are reducing prices for GPT-5.6 Luna by 80% and GPT-5.6 Terra by 20% , and offering a faster option for GPT-5.6 Sol in the API. (1/2)

GPT-5.6 Sol has been used to solve open problems in mathematics. So why was it struggling with ARC-AGI-3, a benchmark of 2D puzzle games? We investigated. The harness was not letting it remember what it had learned. (1/2)

We used GPT-5.6 Sol in Codex to optimize its own infrastructure and performance. These improvements compound across inference and the agent loop, producing more useful work from the same underlying hardware.

After deployment, we applied GPT-5.6 Sol to advance the frontier of efficiency by making itself more efficient to run. The results: - 20% lower serving costs from production GPU kernel improvements. - 15%+ better token-generation efficiency from improved speculative decoding.

We’ve seen the community build with Codex. Chaotic desks, clean desks, couches, airport floors. We don’t judge the workspace. We just love seeing what you’re building. Here are a few of yours, now on billboards.

We’re giving scientists, mathematicians, and engineers free access to our frontier models—starting with 10,000 researchers and expanding to 100,000 through 2027. ChatGPT for Academic Researchers is built to accelerate discovery across disciplines. (1/2)

We quietly released the open-source Codex Security CLI, but Hacker News found it before we had a chance to share it here... You can now use it to scan repositories, track findings across runs, verify fixes, and add security checks to CI/CD. (1/2)

We're introducing two new transcription models in the API: • GPT-Live-Transcribe: built for low-latency live transcription. • GPT-Transcribe: optimized for asynchronous transcription of completed audio files and batch workloads. (1/2)

At the core of our mission is working through how to ensure increasingly powerful AI benefits everyone. We believe that, at some point in the future, AI acceleration for frontier model development may be so high that the world will need to pace the rate of AI advancement. (1/2)

Coding agents are helping scientists spend more time advancing research, taking on everything from routine maintenance and targeted optimization to complete redesigns and new systems. (1/2)

We're opening applications for the OpenAI Student Collective—a program for undergraduate Campus Leads bringing AI innovation to their campuses. Campus Leads will work directly with OpenAI and receive hands-on training, funding, credits, swag, and access to a global community of peers.

At a small business, the person closest to a problem is often the one who has to solve it—even when it falls outside their job description. We studied how AI is becoming powerful generalist tool for small teams, helping them work across functions.

GPT-Live in ChatGPT Voice is now available to Edu, Business, and Enterprise plans globally.

Introducing GPT-Live, a new generation of voice models for natural human-AI interaction. Rolling out in ChatGPT starting today. You’ll want to turn the sound on for this one. Video: https://twitter.com/openai/status/2074907025537224840

Your Pet is ready to meet other builders. On ChatGPT web, create a shareable link for your custom pet and send it to a friend to adopt.

Your ChatGPT Work agent can now use websites that require you to sign in. Take over the cloud browser to log in, then let your agent continue the task. Your login persists across sessions, so you only have to sign in once.

Keep work across multiple folders in one Codex project. Local projects can now include related code, docs, and reference files from multiple folders. Codex can read and write across them while one primary folder remains the Git root.

Your Site is live. And now you can see how it’s doing. Sites Analytics is in public testing, giving you basic performance metrics for the sites you publish with Codex.

Start new tasks, check existing threads, and steer work across Codex and ChatGPT Work as you build out loud in one conversation.

ChatGPT Voice is now in the desktop app. Control your computer and direct multiple agents running in ChatGPT Work or Codex, using just your voice. It's powered by GPT-Live, so it can speak, listen, and coordinate work in the app at the same time. (1/2)

After Kiley was diagnosed with glioblastoma, an aggressive form of brain cancer, doctors told her she might have only months to live. At 18, she wrote a will, chose a casket, and began living scan to scan. (1/5)
