OpenAI rolls out GPT-5-Codex-Mini — faster, lighter, and 4x cheaper
OpenAI has introduced GPT-5-Codex-Mini, a compact code model that offers around 4× more usage than GPT-5-Codex at a slight tradeoff in capability.
● Available now in the CLI and IDE extension for users signed in with ChatGPT.
● API access coming soon, enabling broader developer integration.
● Aimed at high-frequency coding workflows where speed and cost efficiency matter more than full reasoning depth.
OpenAI is quietly optimizing its stack for developer volume not just raw intelligence.
