In Brief<\/p>\n
On Monday, OpenAI launched Codex, an agentic coding tool marketed to software developers. Today, OpenAI also launched a new model designed to turbo-charge Codex: GPT-5.3 Codex.<\/p>\n
The company says that the model transforms Codex from an agent that can merely \u201cwrite and review code\u201d to one that can do \u201cnearly anything developers and professionals do on a computer, expanding who can build software and how work gets done.\u201d Having tested its new model against a number of performance benchmarks, OpenAI claims that it can create \u201chighly functional complex games and apps from scratch over the course of days.\u201d<\/p>\n
OpenAI says that GPT-5.3 Codex is also 25% faster than its previous model (GPT-5.2) and that it was the company\u2019s first model that \u201cwas instrumental in creating itself,\u201d meaning that the company\u2019s staff used early versions of the program to debug itself and evaluate how it was performing.<\/p>\n
The new model release notably follows hot on the heels of a new agentic coding model released by its competitor, Anthropic. Indeed, OpenAI and Anthropic had originally planned to release their two agentic coding tools at the exact same time: 10 a.m. PST. However, not long before the original release time, Anthropic moved its release date up by 15 minutes, slightly besting OpenAI in the race to publicize the models.<\/p>\n
