What is GPT-6.1 Sol?

GPT-6.1 Sol is OpenAI's upgraded Sol model for developers and professionals who need advanced reasoning and agentic capabilities without the higher cost of GPT-6 Astra. It is designed for coding, professional knowledge work, computer use, scientific research, factual question answering, and multi-step business workflows. OpenAI describes GPT-6.1 Sol as approaching GPT-6 Astra's intelligence across several important workloads while charging one-fifth of Astra's standard input and output token prices. On DeepSWE v1.1, which evaluates long-horizon software engineering in real codebases, GPT-6.1 Sol matches GPT-6 Astra at approximately one-fifth of the cost and exceeds GPT-6 Sol's best score by 6.4 percentage points. Its professional-work capabilities include understanding complex PDFs containing tables, charts, diagrams, and fine-print details across fields such as finance, healthcare, and legal work. On AutomationBench, GPT-6.1 Sol improves on GPT-6 Sol by 4.8 percentage points at the same reasoning setting and scores 2.2 points above Opus 5.5 at medium reasoning effort. Computer-use performance also advances significantly, with GPT-6.1 Sol outperforming GPT-6 Sol by seven percentage points on the OSWorld 2.0 offline set at maximum reasoning effort and coming within 2.1 points of GPT-6 Astra. For scientific research, the model can work with code and terminal tools on workflows involving data analysis, simulations, model fitting, and theorem proving, more than doubling GPT-6 Sol's Terminal-Bench Science 0.1 score at maximum effort. OpenAI also reports improved factual accuracy, including a reduction in the factual-error rate from 11.4% with GPT-6 Sol to 7.7% with GPT-6.1 Sol at low reasoning effort on its deliberately difficult factuality evaluation.

What is GPT‑5.4 Thinking?

GPT-5.4 Thinking is an advanced reasoning model available in ChatGPT that focuses on solving complex problems through structured analysis. Built on the GPT-5.4 architecture, it combines enhanced reasoning, coding abilities, and AI agent workflows into a single powerful system. The model is designed to assist users with demanding professional tasks such as research, document creation, data analysis, and strategic planning. One of its distinguishing features is the ability to provide an initial outline of its reasoning process before delivering the final response. This allows users to guide or refine the direction of the solution while the model is still working. GPT-5.4 Thinking also improves deep web research, enabling it to gather information from multiple sources to answer highly specific queries. The model maintains stronger context awareness during longer conversations, helping it stay aligned with the original task. These improvements allow it to handle complex workflows with greater reliability. GPT-5.4 Thinking also benefits from improvements in tool usage and integration with professional software environments. Its reasoning capabilities help reduce errors and improve the accuracy of generated outputs. This makes it suitable for tasks that require careful analysis and multi-step planning. By combining transparency in reasoning with powerful analytical capabilities, GPT-5.4 Thinking helps users achieve more precise and efficient results.
