💥 Today we’re launching Codex: a software agent that operates in the cloud and can do many tasks in parallel. In the future most code will be written by AI; society will be accelerated because of it. This is a research preview, but we’re very excited to see what you build.”” / X https://x.com/kevinweil/status/1923403368849871329
2025 is the year of agents.”” / X https://x.com/gdb/status/1923541152508281329
A user can then review code suggestions made by the agent. It can show a preview of the test it ran. And the user can then create and push a PR. https://x.com/omarsar0/status/1923398310812918226
Best way to use Codex is to create PRs liberally. Feels like a very different way of writing code!”” / X https://x.com/gdb/status/1923530399692750978
Codex CLI keeps getting better. In the long run, I expect that “”local”” (e.g. Codex CLI) and “”remote”” (e.g. Codex) coding agents will come together — imagine their combination as a remote coworker who can also look over your shoulder.

One thing the Deep Research models make clear is letting AIs agentically use their own tools to do search & see the outcomes can result in much better outcomes than RAG.
