GPT-5.3 Instant delivers more accurate answers, better web synthesis, fewer unnecessary refusals, and a more natural tone without the cringe, caveats, or dead ends. It writes with more range, responds with better judgment, and stays focused on what you actually asked. Same speed. Sharper results. Better conversations by default.
Turn text prompts and images into hyperreal videos with sound using the models from OpenAI. A single sentence can unfold into a cinematic scene, an anime short, or remix of a friend's video. If you can write it, you can see it, remix it, and share it.
It looks like OpenAI may have acqui-hired the @Cline team. It's not currently clear what that means for the future of the AI coding agent as a project, as their team members are now on the @Codex by OpenAI team.
Any open-source alternatives? @Kilo Code? @Zed? else?
The official Codex desktop app by OpenAI brings parallel coding agents natively to Windows. It isolates tasks in OS-level sandboxes and dedicated worktrees so agents can write, test, and propose code without trashing your local environment.
A new platform that helps enterprises build, deploy, and manage AI agents that can do real work. Frontier gives agents the same skills people need to succeed at work: shared context, onboarding, hands-on learning with feedback, and clear permissions and boundaries. That’s how teams move beyond isolated use cases to AI coworkers that work across the business.
Advances the frontier of coding and computer work. SOTA on SWE-Bench Pro (57%) and OSWorld (64%). Features mid-task steerability (interact while it works), 25% faster speeds, and "High" capabilities in cybersecurity.
FrontierScience is a new benchmark for evaluating AI’s expert-level scientific reasoning across physics, chemistry, and biology. It measures both Olympiad-style problem solving and real research tasks, helping track how well advanced models can support and accelerate scientific work.
An AI agent social network: When we asked about social networking ambitions beyond Sora, Simo went somewhere unexpected: What happens to social relationships in a world where everybody has their own personal agents? And how can these personal agents help you manage your social relationships in a better way? She framed it not as agents aimlessly talking to agents like Moltbook, but as AI mediating existing human relationships. We haven t cracked what that will look like, but I think that s a very interesting area.
