GPT-5 Codex vs Claude Code: free attack on Anthropic
OpenAI introduced GPT-5 Codex. A specialized version of their flagship model, completely reimagined for programming!
The new model replaces the outdated o3 in the Codex web client and is already available in local tools Codex CLI and plugin for popular IDEs. The access policy is interesting. The service is free for all ChatGPT subscribers regardless of plan. Essentially, GPT-5 Codex is a direct attack on competing solution Claude Code from Anthropic.
The model underwent specialized fine-tuning on a large dataset of real tasks. From creating projects from scratch to large-scale refactoring and code reviews. Although improvement on standard SWE-bench Verified benchmark seems insignificant. 74.5% versus previous 72.8%. But OpenAI says their internal tests show impressive jump in refactoring tasks. From 33.9% to 51.3%. We have to take their word for it.
The most interesting achievement is adaptive distribution of computational resources. The model generates shorter responses for simple tasks and more detailed ones for complex ones. According to OpenAI, GPT-5 Codex also demonstrates unprecedented autonomy, working up to 7 hours straight on complex tasks. Iteratively improving solutions and fixing errors in tests.
