Garry Tan introduces gstack, a toolset designed to streamline software development using AI. By simulating a team of specialized roles, it enables solo developers to ship code faster and more efficiently. The article outlines its features and how it transforms the development process.

• Garry Tan claims he shipped 600,000+ lines of code in 60 days while running Y Combinator, using this workflow
• gstack packages 15 Claude Code tools that simulate a full team (CEO, Designer, Eng Manager, Release Manager, Doc Engineer, QA) so one person can run a solo "software factory"
• The toolset is open-source and installable, giving solo developers a structured command-based workflow from planning through shipping

OpenAI is rolling out a new model called GPT-5.2-Codex-Max for subscribers, which enhances the capabilities of its Codex tool. This version improves performance on long tasks, tool use reliability, and understanding of visual content, building on the features introduced in GPT-5.2. Further details about the model are expected to be released soon.
