GPT-5-Codex Now in Cline

GPT-5-Codex is a specialized version of OpenAI's GPT-5, designed specifically for coding applications and available through the Cline provider. It offers a 400K context window and competitive pricing that matches GPT-5. The model excels in adaptive reasoning, using significantly fewer tokens for simple tasks and extending its processing time for complex coding challenges like refactoring and debugging, thereby outperforming GPT-5 in internal tests and SWE-Bench coding tasks. Unlike its general-purpose counterpart, GPT-5-Codex is optimized for real-world engineering tasks, providing more steerable and concise code outputs. It features variable thinking, which dynamically adjusts reasoning effort and works seamlessly with Cline's thinking slider, allowing users to tailor the model's processing intensity to their needs. Users are encouraged to try GPT-5-Codex and share their experiences on platforms like Reddit or Discord.
