How we used Codex to build Sora for Android in 28 days | OpenAI
If you’re wondering whether we used a secret model, we used an early version of the GPT‑5.1‑Codex model – the same version that any developer or business can use today via CLI, IDE extension, or web app. Prompt: figure skater performs a triple axle with a cat on her head · When Sora launched on iOS, usage exploded. People immediately began generating a stream of videos. On Android, by contrast, we had only a small internal prototype and a mounting number of pre-registered users on Google Play.
Using Codex CLI remotely using your mobile device
I don’t know about you but I ❤ the basic simplicity of Codex via the CLI. During the recent 5.4 Open AI announcement, this request came up. Now, this is not perfect, but goes a long way to meeting this requirement already: Prerequisites An OpenAI ChatGPT or platform (API) account. More on community.openai.com

Updates to Codex usage on Plus
Everyone is misreading this. It refers to purchasing addition credits after using up your subscription quota, so it can't be used as a loophole to undercut API pricing. More on reddit.com
FYI: Codex limits dropped by half after the 2x promo ended and Plus usage has changed
Do people just spam 5.4 all day? It has insanely high usage compared to 5.3. 5.3 is still pretty good for general longer sessions. 5.4 you'll run out in like an hour More on reddit.com
Can I use the OpenAI Codex app on my Android phone?
Officially, there is no support for the OpenAI Codex app within the Android ChatGPT app. The common workaround is to save a shortcut to the web interface on your homescreen, but it's not a native or seamless experience.

What is the biggest limitation of the OpenAI Codex app?
Its biggest limitation is the sandboxed environment it runs in. For security, network access is disabled by default, which means the OpenAI Codex app can't perform common developer tasks like installing dependencies, fetching data from APIs, or connecting to a database.

A Month With OpenAI's Codex
March 1, 2026 - This classic version had legacy audio APIs, defunct Flurry analytics, and a bunch of cruft built up from its years of progressing from the original iPhone to larger devices, iPad and Mac, and I wanted to see how Codex would handle migrating it to Swift and modern APIs compared to my own. It performed the migration in one shot. Not a line of ObjC remained, and the app built and ran first time. The audio worked, the gameplay worked, and the custom animated settings screen was intact. So far, so boring. What I really wanted to have it try was to port this classic SameGame app to Android, a task that ChatGPT's agent feature had failed at a year ago.

Codex rate card | OpenAI Help Center
1 day ago - If you're an Enterprise customer and have questions, contact OpenAI Sales. The legacy rate card shows approximate average credits per message or pull request. The updated token-based rate card shows credits by token type. Credits remain the core pricing unit that customers purchase and consume. The updated token-based format makes credit usage easier to map to actual model activity, aligns Codex pricing more closely with token-based metering, and gives clearer visibility into how input, cached input, and output contribute to total usage.
