ChatGPT 5.5

ChatGPT 5.5: Open AI’s smartest and most intuitive to use model yet, and the next step toward a new way of getting work done on a computer. If you prefer GPT 5.5 its the right choice, the gains are especially strong in agentic coding, computer use, knowledge work, and early scientific research—areas where progress depends on reasoning across context and taking action over time. GPT‑5.5 delivers this step up in intelligence without compromising on speed: larger, more capable models are often slower to serve, but GPT‑5.5 matches GPT‑5.4 per-token latency in real-world serving, while performing at a much higher level of intelligence. It also uses significantly fewer tokens to complete the same Codex tasks, making it more efficient as well as more capable. Codex, is a cloud-based AI software engineering agent developed by OpenAI, designed to automate complex, multi-file programming tasks, bug fixes, and pull requests, powered by a specialized version of OpenAI o3. It operates in a secure sandbox, allowing it to work across repositories, manage workflows, and execute tests independently.
