About

GPT-5.5 Thinking is an advanced AI capability from OpenAI designed to handle complex, multi-step tasks with greater intelligence and autonomy. It enables users to provide high-level instructions while the model plans, executes, and refines tasks independently. The system excels in areas such as coding, research, data analysis, and document creation. It can navigate across tools, check its own work, and adapt to ambiguous or incomplete inputs. GPT-5.5 Thinking is optimized for both speed and efficiency, delivering high-quality outputs while using fewer computational resources. It also supports long-context understanding, allowing it to process large datasets and extended workflows. Strong safeguards are built in to ensure responsible and secure usage. Overall, it represents a shift toward more autonomous, agent-like AI that can complete real-world tasks end-to-end.

About

OpenAI Bel is the reported codename of an unreleased artificial intelligence foundation model associated with OpenAI. Unofficial reports describe it as a large-scale pretraining project intended to support future generations of AI models. The project has been linked in speculative reporting to OpenAI's Astra model family and potential successors to GPT-6. Some sources claim that Bel contains more than 10 trillion parameters, although this figure has not been independently verified. OpenAI has not published official technical specifications, benchmark results, or documentation confirming the project's capabilities. Bel is not currently available as a publicly documented model through ChatGPT or the OpenAI API.
