I Left AI Agents Overnight (Fable 5.1 vs GPT-6 Astra)

From the creator

πŸ”— Join Private Community: https://go.sleeautomation.com/oji πŸ”— Free Resources: https://go.sleeautomation.com/uku I built an AI agent world that runs my entire business inside a video game interface, and I built two versions at once so I could compare GPT-6 Astra against Fable 5.1 side by side. This is a full team of autonomous AI agents (SEO, content, finance, video editing) that I can walk up to, press E to talk to, assign work, and approve or reject their drafts before anything goes live. The wild part: I let it run overnight and woke up to find my content agent had spun up two sub-agents on her own and started building Etsy listings to make money that I never asked for. You'll see exactly how each department works, how the approval system keeps the agents from acting without my sign-off, and an honest breakdown of where each model wins. Fable 5.1 nailed the gaming vibe I wanted but needed a few passes to grasp my prompts. GPT-6 Astra was slower and burned way more tokens, but understood requests on the first try and shipped features I didn't even ask for. No sponsorship here, so this is my real experience with both. If you want the tools and the step-by-step to build your own agent world, drop a comment and I'll film the follow-up next week.

AI Maker Residence at KOKO

The third AI workshop taught by our legendary teacher, Nick Sarafa. In one of the last events we did an asset manager raised an additional Β£25M on their fund within a space of 9 months. This is a full-day hands-on training workshop for purposeful co-creation with AI using Claude Code. Imagine having access to hundreds of billions of dollars of computing power and knowing exactly how to make it work for you through the power of super intelligence. One person did.
