Prism is now powered by Codex, giving it real agentic superpowers. Try it out!

We integrated the Codex harness into Prism (https://t.co/cmEsJYRtW9) — this means you get skills, reasoning levels, and the raw tenacity of the Codex model in your LaTeX environment.

Oh and we also built version mgmt into Prism, which was one of the top requests.

See below thread from @vicapow for some great examples of the power of Codex inside Prism 👇

did you know there was a brief time about 150 years ago when we used editors with ai tab autocomplete?

[Guillermo Rauch @rauchg]

Every time GitHub has an outage our team is paged. Incidents at Vercel get automatically filed by anomaly detection systems.

We just detected an outage 16 minutes before their status page changed. Deployments suddenly dipped and surged.

Despite all the chatter about coding AGI, the reality is that software infrastructure remains an extremely hard problem.

I have no doubt the GitHub team is highly competent, and there's no shortage of models and agents available to them. Don't forget this is the company that brought us Copilot, the first major breakthrough product in AI coding. Yet clearly the prompt "/goal scale GitHub, make everything extremely fast, make no mistakes" is not enough.

The hard parts of software remain very hard, especially under unprecedented demand, as more people join in on the fun of building new things.

Codex is a gazillion times better than Claude Code or Cowork for knowledge work.

Needs a rebrand desperately.

@curtisalvin @Bartfare @SFBART That announcement from the operator made everyone take off their headphones and go “…what”

[DHH @dhh]

I've had more "I can't believe it's this good" moments with GPT5.5 than any other model since Opus 4.5. It's shockingly, scarily capable. Days and days of amazing progress. All steering, no handwriting. Yet utterly delightful to conduct its coding. So, so good.

[Tibo @thsottiaux]

A little secret. About 5% of our production traffic is on the Pi harness, about another 5% is on OpenCode. Reminder you can use your ChatGPT account in a flourishing set of other tools.

We’ll continue to make Codex awesome, but you have options.

[DHH @dhh]

For complicated agent work, it's amazing how much GPT5.5 has improved. I found 5.2 to be very far behind Opus. Now using Opus 4.7 after 5.5 feels like a big step backwards. Gotta love this level of competion! Strong comeback for OpenAI.

[Matt Shumer @mattshumer_]

Just wiped the Mac Mini I set up for OpenClaw.

I’m turning it into an always-on devbox to use with Codex mobile.

Have a feeling this is gonna be amazing.

[Tibo @thsottiaux]

Codex everywhere

[Jane Manchun Wong @wongmjane]

You can just put your whole bike in a @Zoox

@Peter_J_Beck The water caught fire

[Aleksey Smolenchuk @lxe]

don’t forget “use subagents”

[Aleksey Smolenchuk @lxe]

@jamiequint 200mb? Just upload to YouTube as a video

[Beff (e/acc) @beffjezos]

coding with Codex 5.5 instead of Claude 4.7

[Sanjna Mohan @sanjna_mohan]

Finallyyy!! @zoox just leveled up 🥳

[Aleksey Smolenchuk @lxe]

@can yes it… can

switched my openclaw from pi to codex harness
it's a 'one-shot any task to completion' machine

[Andrew Ambrosino @ajambrosino]

Codex for everything:

- Dynamic UI for the task at hand
- 20% faster computer & browser use
- Even better slides and sheets
- Annotate in browser, artifacts, and code
- Easier to get started
- Cleaner design across the app
- Performance improvements
- (no clunky handoff/switching)
