According to Sam Altman on Twitter, OpenAI has released GPT-5-Codex, a specialized version of GPT-5 focused on agentic coding. This new model is designed to be significantly faster and smarter than its predecessors, with enhanced capabilities that facilitate more autonomous and efficient code generation. For businesses and developers, GPT-5-Codex opens up new opportunities to automate complex software development tasks, accelerate product cycles, and lower operational costs. The introduction of agentic coding features positions GPT-5-Codex as a potentially transformative tool for AI-driven software engineering, supporting the growing demand for scalable, intelligent automation in enterprise and startup environments (source: Sam Altman, @sama).
