Summary
Riley Brown, a creator with over two million followers, delivers a two-hour walkthrough of 28 practical capabilities of OpenAI’s Codex paired with the GPT-6 Astra model. The video is structured as a desktop-app tutorial, distinguishing Codex (the application) from GPT-6 (the underlying model) and walking viewers through setup, plan selection, and the core interface before systematically demonstrating each capability.
Features covered include multi-task parallelism (running multiple agent jobs simultaneously), project-based file organization that maps to local directories, Slack integration for summarizing team activity, 3D asset generation in Blender and Unreal Engine, interactive document and presentation creation, multiplayer game prototyping, and computer-use mode that allows Codex to operate the desktop autonomously for extended tasks. Brown demonstrates these capabilities live within the ChatGPT desktop app, showing real outputs and narrating what the agent is doing at each step.
The video is primarily aimed at non-technical users and small business operators looking to understand the practical scope of GPT-6 Codex without deep programming knowledge. While it is creator-produced rather than from OpenAI directly, it provides a comprehensive survey of the interface and covers edge cases such as usage limits across the $20 and $100 per month plans, how to organize long-running projects, and how to use the in-app browser for research-heavy workflows.
