🚀 Run GPT-6 Astra, Fable 5.1, Even Other Agents Simultaneously in This Free AI Workspace

It lets me run GPT-6 Astra, Claude Fable 5.1, Codex, Grok, Kimi, and other agents together. I can keep the same files, or any assets while choosing the best model for each task.

TL;DR

A free AI agent workspace can run GPT-6 Astra, Claude Fable 5.1, Codex, Grok, Kimi, and other AI coding agents on the same project files. This makes it easier to test new models without rebuilding your whole workflow.

The main idea is simple: keep your work inside one AI OS folder. Your files, thumbnails, prompts, skills, MCPs, brand rules, and instructions stay in one place while different agents work from the same base.

This guide shows how to open that folder, start multiple agent sessions, and run the same task across different models. You’ll also see why a model-agnostic setup matters when new AI models keep improving so fast.

Key points

  • Multiple AI coding agents can work side by side on the same folder.

  • Avoid building your workflow around one single model.

  • Keep your skills, instructions, and assets organized before testing agents.

Introduction

A new model comes out, everyone says it's better, and suddenly you start rebuilding your workflow again.

First it was Claude Fable 5.1. Now it's GPT-6 Astra. Tomorrow it could be Codex, Grok, Kimi, or something else.

And every time, you move files, copy prompts, recreate instructions, set up tools again... I hate this. That's why I got interested in this free AI workspace.

It lets you run GPT-6 Astra, Claude Fable 5.1, Codex, Grok, Kimi, and other agents side by side, all using the same files, assets, instructions, skills, and project context.

And everything stays inside the same AI environment. I think this is a much better way to work with AI.

In this guide, I'll show you the free AI workspace I'm using, how I connect multiple models to the same AI OS folder, and why this approach could save you a lot of time as new models keep appearing every month.
