Cool projects our community is cooking with Codex:

I get good performance out of codex by having Opus 5.5 run codex agents

这次真的是cook啊

i built it with codex❤️

Those projects look really interesting and innovative

The best community

The amount of safeguards add so much unnecessary bureaucracy. It is absurd levels. No cooking on complex codebases, just flaws and constant guardrails messing context.

codex continues to unlock new paradigms for complex problem solving and developer velocity

In 1963 John Cage needed a relay of a dozen pianists to play Satie's Vexations 840 times, and it still ran over 18 hours. 99 agents on 99 pianos finally solves the real bottleneck: bathroom breaks.

I'm using Opus paired with DeepSeek to replace my GPT workflow. The UIs they design are amazing.

a musician using Codex to build their own instruments is so much more exciting than another AI that generates a song from a prompt. give people new ways to create, not just finished content.

what i want from each one is the boring part: how much of the repo is still the code the agent wrote first

Did codex build most of this one on its own, or was there a lot of steering along the way?

People are pushing Codex way past basic boilerplate

Not community, CUSTOMERS

i'm building sandhive to turn them into polished posts at light speed!

And here's what's codex can actually cook in benchmarks:

Who will win?

I'd love a showcase of the less flashy side too, like Codex working in a big codebase where every change goes through code review and the agent only has the permissions it needs. That's where most companies are trying to get.

The BusyBar saves the demo from voice-assistant limbo

Am here for it, cant wait for the codex combo

love that the showcase is mostly soldering now and not just another todo app

“酷炫”项目容易，能上生产才是门槛。Codex 生成的东西，最贵的不是写代码，是后面有人得 review、补测试、兜权限。社区项目真正该晒的是跑多久没出事，不是 demo 多惊艳。

cool projects and not one of them is a maintenance script. the boring stuff is still ours

What is this ?

Half these "community projects" are just API wrappers with a UI. What's the most complex thing someone's actually built?

Week three is where these usually stall.

the companion robot one got me — Codex didn't just help code it, it designed the whole circuit board too. that's way past autocomplete

Codex in the wild is the stuff worth watching, honestly I'd check which repos they're shipping on.
