Now that “Scene 0” works as a tutorial, next step is building the start menu and a save system for upcoming chapters and scenes. Step by step 💪 #vibecoding #gamedev #threejs
Jesús Muñoz@quejicus91

Here we go again!!! Codex UI (where chapters and lore will live) with placeholders for now. Getting more excited with every new feature added! Everything coded with GPT-5.3-Codex + Three.js, and UI assets generated with Nano Banana Pro + Meshy (3D characters) + Hailuo (background loop) + ElevenLabs (voices and sounds). We keep building! 🥳

We're introducing Codex Security. An application security agent that helps you secure your codebase by finding vulnerabilities, validating them, and proposing fixes you can review and patch. Now, teams can focus on the vulnerabilities that matter and ship code faster. openai.com/index/codex-se…

Over the last 3 months, Articles on X have grown 18x. It is one of the fasting growing new products on the platform. Today we're making them even better: we're launching a Listen feature—powered by Grok Voice. You'll be able to listen while scrolling Timeline or on-the-go from your lock screen. It's now available on iOS for top Articles in English and launching on more platforms soon. Here's how it works:

Couldn't help it! Had to give GPT 5.4 (High) + /fast mode a try. → Added height terrains to the level → Animation tweens for the jumps Used xHigh to solve a gnarly bug with the controls successfully 💪 This Final Fantasy Tactics-inspired game was completely vibe coded!

GPT 5.4 has been released... + 1M context window! Here's how to enable in Codex: → 1. ~/.codex/config.toml → 2. model = "gpt-5.4" → 3. model_context_window=1000000 → 4. model_auto_compact_token_limit=9000000 Run codex → 5. /statusline → 6. toggle context-window-size I didn't even realise Codex had a statusline tool!

@dangreenheck That’s so cool! Great job, Dan 👏 Sharing some WIP could also be really useful for getting feedback 🙌

I generally don't like sharing WIPs because I like to project the illusion of mastery, but someone asked so here you go! Wrapping up the underwater code with sun shafts and particles. Needs some additional wave interactions and dynamics, but it's getting there! Occlusion with scene objects is working nicely though—cool to see the light rays interact with the hole in the keel. P.S. I was getting lonely working on this so I added some fish buddies. At 0:08, Steve wanted to say hello 👋

Codex 0.107.0 is here, and with it: FORKS🍴 This minor update includes the ability to fork your current chat history directly with custom multi agents with just a quick prompt. "Fork this session using n subagent(s)" This unlocks some interesting use-cases where you can launch multiple agents that retain all of your chat history up to that point, each in their own independent session. For example, you've been discussing architecture with Codex for 20 minutes, talked through constraints, reviewed existing code, settled on a model. Now you want to see two different implementation strategies side by side. Fork lets both children start from that full shared understanding. With a normal spawn, you'd have to re-explain the entire context to each child, and they'd inevitably miss nuance from the earlier conversation - which is basically a form of compaction/compression. With something like this, you could also just tell it to fork itself 5 times, and implement the same UI/frontend 5 different times in their own worktree to see which one you like the most. Other potential uses: - branching after reviews - try and rollback patterns using worktrees - parallel debugging strategies Otherwise, this is a minor update with improvements to the app server, realtime transcription, and memory. Enjoy!

@quejicus91 I don't know but it would be worth testing whenever it drops for sure. I topped up 10 Yuan in API credits 4 months ago, and I still have 8 Yuan left 😂
