Codex is gaining steam
but I wish it had this
Hey folks,
I spent most of the bank holiday weekend offline for a change whilst at a wedding in the English countryside. I would’ve been more online if Codex had a mobile app but still waiting on that… this morning I did just install this skill that lets you iMessage Codex which is pretty great - essentially keeps a thread open in the app that you can message. Just paste the link in Codex and it’ll guide you through everything.

OpenAI wants non-technical users to use Codex. They are making it easy for you to switch to Codex. You can now import settings, plugins, agents, project configuration and more into Codex (from tools like Claude Cowork). They are directly improving features related to everyday work, like creating slides/sheets, plus friendlier UI changes.
Grok 4.3 is out in the API. 1M context, text + image input, reasoning and a December 2025 knowledge cutoff. It’s priced $1.25/$2.50 per million input/output tokens, i.e. much cheaper than Sonnet 4.6 for a relatively similar performance.
Entire, the company by GitHub’s ex-CEO, released two new things: git-sync - a utility to mirror git repos from a source to a target without needing to clone it locally and Dispatches - a feature on their web platform to generate release notes from recent ships, commits, and agent sessions by repo/date range.

The 'gaining steam' read tracks. Codex finally feels like a real agent, not fancy autocomplete. What I keep waiting for is durable project memory across sessions, not a fatter context window. Until that ships, the teams I know still lean on Claude Code or Cursor for long-running work and use Codex for one-shot tasks.
