What is GPT-6.1 Sol?

Large language models are computer programs trained on huge amounts of text so they can generate, summarize, translate and analyze language. A hard part of the field is that their output can read as fluent and natural yet be factually incorrect, and it is not clear how they perform linguistic tasks internally. GPT-6.1 Sol is a model from OpenAI, part of its GPT-6 series. The maker describes it as delivering near-Astra performance at a lower cost for complex coding, computer use, and professional work, where OpenAI calls GPT-6 Astra its most powerful model.
