OpenAI Announces GPT-5-Codex for AI Programming Assistance
By

Pure flour-power. Hearty enough to carry you through lunch.
Summary
OpenAI has announced GPT-5-Codex, a fine-tuned variant of GPT-5 specifically designed for AI-assisted programming tools. The model is currently in a 'half-released' state as it's not yet available via OpenAI's API, but the company plans to make it accessible soon. This release adds to the existing confusion around OpenAI's various products that share the 'Codex' name, though the new model's naming with two hyphens helps provide some clarity.
