Over the next 28 days, each day we’ll either ship one thing that is a clear improvement and relevant for most codex/work users or ship a full reset. Let the improvements begin.

Day 22/ Terra is back! Our first model that is significantly better at writing, personality and nuanced understanding of requests. Packs a punch across the board, very good at computer use, and gives 2X more usage than 6.1 Sol across API and subscriptions.

Day 21/ Wonder what happens the remaining seven days. But today is a reset.

It is all propagated. Enjoy some mad codexing tomorrow. Fun week ahead too.

By midnight PST

On codex cli updates. We've added reusable prompt presets, inline model and permission settings, and enterprise MCP sign-in. We've also fixed failures when resuming long sessions and added Windows corporate-proxy authentication. Surprisingly the CLI has grown 2X in usage since devday.

Day 19/ Small updates. Calls connect much faster for dots, changing reasoning in codex & work mid conversation does not invalidate cache anymore and a we've also updated the codex cli.

Landing tomorrow before 10am PST together with a small ship.

Lands tomorrow before 10am PST.

Day 16/ You can now cache for 12h in the API and for logged in users across Codex & Work we keep cache forever and you don’t have any penalty for coming back to an old conversation or resuming after a few hours and are now guaranteed to hit the cache.

Day 15/ Nevermind, we're still cooking... and reset. Enjoy.
