A milestone for our infrastructure: our first NVIDIA Vera Rubin racks are here and now running our training stack. This is an important step as we expand compute that powers OpenAI's next generation of frontier AI pre-training.
Frontier AI is a systems problem. You have to optimize every layer of the stack, not just the GPUs.
Ted Nyman@tnm·happy friday we've continued our work on git here at @openai. performance, correctness, & testing improvements are flowing from openai/git to upstream. perf improvements in codex app too; you'll see more efficient use of git in new builds. follow along: …enai-git-upstream.openai.chatgpt.site x.com/tnm/status/207…
This is not a "misconfiguration".
Sam Altman@sama·major price cuts today: *80% drop for GPT-5.6 Luna, now $0.20 per million input tokens and $1.20 per million output *20% drop for GPT-5.6 Terra, to $2/$12 *GPT-5.6 Sol gets Fast mode in the API, up to 2.5x the speed for 2x the price, same intelligence
Defend, together.
OpenAI@OpenAI·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. This is an early release, and we're listening to your feedback as we continue improving it.
Competent AI agents can now find zero-days, chain exploits, and cross trust and organization boundaries at machine speed. The right response isn’t fear. It’s better sandboxes, least-privilege access, continuous monitoring, AI-assisted defense, and sharing what we learn. The future is defensible if we build it together.
clem 🤗@ClementDelangue·The first autonomous agent cyberattack is an unprecedented event that deserves unprecedented transparency. Today we’re sharing everything we can: a full technical timeline, an interactive replay, and how we used an open model to defend ourselves, so defenders everywhere can learn from it and prepare for what’s next. t.co/uPxIpjW8Xn
Our Agentic Engineering Acceleration efforts just got a serious turbocharge. Excited about what’s ahead, will keep you all posted on internal progress we’re looking forward to sharing soon.
Taylor Blau@ttaylorr_b·First day at @OpenAI today! Couldn’t be more excited to start working on SCM tools. Many thanks to @tnm, @gdb, @aglover, @iamveeve, @udayruddarraju, and lots of others. Let’s go!
Far from being dead!
Latent.Space@latentspacepod·Is pre-training dead? @OpenAI Chief Research Officer @markchen90 doesn't think so: "We've always found some kind of technique whether it be better engineering or some new research insight that helps you break past the boundary." x.com/latentspacepod…
