Day 1 of building GTA 6. Still feels fake typing that out. Upgraded to Claude Max 20x just for this. Spent a couple hours getting the whole project structured and pushed to the repo. Sandbox is up and running. No studio, no publisher. Just whoever shows up. We picked Godot on purpose: it's community-owned, so nobody can pull an EPIC on us later and rewrite the deal once we're invested. The goal: beat the real GTA 6 to launch. Ambitious, probably stupid, doing it anyway. If you can model, code, build levels, or write music and lore, come join. Looking for a couple contributors to cook this. Time to cook. Reply if you're in.

Union Alpha is now in Codex!! The speed is insane over 300 to 400 tokens a second, 262k context, images in, and it's free for a week. It's a good timing too, most of the Codex usage is basically gone right now. Zai did this exact thing in August: Ox Alpha showed up unnamed, free for a week, built for agentic coding, and a week later it was GLM-5.3-Flash. So what model do you guys think it is?

OpenCode Go is now wired into Codex!! The pricing is insane. $10 gets you 10,000 DeepSeek requests every 5 hours (no weekly limits). I converted that into DeepSeek API dollars because I thought I was reading it wrong, and the same 5 hours of usage would run somewhere between $10 and $30 depending on how big your context gets. So one afternoon of use already covers the whole sub. It comes with Kimi K3 as well. Both sit in the picker next to my other models now. Next time we hit a limit in the middle of a loop, we can grab it and keep going.

Codex can run Qwen-3.8-max now as well!! Alibaba most capable model, dropped today and it's already in my codex picker. It's a token plan subscription, not metered api billing. You take the key from your Qwen plan, drop it into Codex Router, and it spends down the plan instead of your card. There's a catch though. Qwen's official setup switches your whole codex over to them, so your ChatGPT models stop showing up at all. That's exactly what Codex Router is for. It adds models to the list instead of replacing them, so sol, Grok, kimi, Deepseek and now Qwen 3.8 max all sit in the same picker and it can grab whichever one suits the job. Router's open source, setup's in the video 👇

Muse Spark 1.3 is now in Codex!! OpenCode's free tier runs it for nothing, and $10 on OpenCode Go gets you over 45,300 requests. It's basically Opus 5 tier too. There's a catch though. Meta may use your inputs and outputs for training, which is the whole reason the tier is called contributor and the whole reason it's free. Muse 1.3 just sits in the picker next to my paid models now. I'll just use Astra + Muse Spark for subagents. Gonna keep everything in stock in case we need it.

Codex can now run Deepseek-v4- flash! There's a catch though. Deepseek's official setup switches your entire codex over to them, so your GPT models stop showing up at all. This is exactly what Codex Router is for. It adds models to the list instead of replacing them, so sol, grok, kimi and deepseek all sit in the same picker and i just grab whichever one suits the job. Deepseek v4-flash is $0.28 per million output tokens. opus 4.8 is $25. same picker, 89x apart. Links in the comment. setup's in the video 👇

AAA studios spend $200M on a city this good. Ours cost $1,500 and swapped Miami for SF within a week. An agent did it in a loop while we slept, now he's working on the traffic and pedestrian.

Tested Fugu-ultra on the questions that break most of the AI: - how many r's in strawberry - is 5.11 bigger than 5.1 - the famous car/wash question (Twice) I think we just got Fable Back

Grok 4.5 is now in Codex now too. No API key, no billing setup, no config file. If you have X Premium, you sign in with your X account and Grok 4.5 runs inside your Codex. OAuth handles it. Your subscription is your access. That's it. And Grok 4.5 just got a lot better, so if you already pay for X Premium, you can now run it in Codex for free.

A loop of AI agents built me a gun. It just can't make it shoot. Day 11 of building GTA 6 with a loop of agents. Yesterday I said today they'd learn to steal cars and shoot. Today's progress: - 2 weapons in - Pickup system works (we can grab weapons now) The downside: you pull the trigger, nothing happens. The loop is incredible at the overall, but shooting is the main part of the game, so I think we wire this one up ourselves. So here is the progress I'm taking shooting and sitting down to learn the physics myself with agent as support. At the same time J A Z I I takes driving by hand. The agents keep doing what they're good at. They're building out the police system and the economy right now, while I type this. Also spent the weekend in SF at a Tripo3D Donut event learning 3D art.

I couldn't stop checking if Fable was back. So I made it check itself.
