OpenAI: GPT-6.1 Sol1.05M contextfrom $0.1 / M tokens2 providersGPT-6.1 Sol is an upgrade to GPT-6 Sol from OpenAI, positioned below the flagship GPT-6 Astra in the GPT-6 series. It is suited for agentic coding, computer use, document-heavy professional work, and multi-step business workflow automation, and approaches Astra-level results on these tasks at a much lower cost. Compared with GPT-6 Sol, it makes fewer factual errors and is more reliable at respecting explicit restrictions and user intent during agentic tasks.
OpenAI: GPT-6 Luna1.05M contextfrom $0.01 / M tokens2 providersOpenAI: GPT-6 Luna is a fast and cost-effective model in the OpenAI GPT-6 series, positioned lower than GPT-6 Sol. It is suitable for high-concurrency and latency-sensitive workloads such as chat, classification, and lightweight agent tasks; at higher inference workloads, it can take on complex software engineering and computer usage tasks that previously required Sol-level models. It shares the improvements in factual reliability of the GPT-6 family, as well as a clearer, more concise communication style.
OpenAI: GPT-6 Sol1.05M contextfrom $0.1 / M tokens2 providersOpenAI: GPT-6 Sol is a cost-effective high-end model in the OpenAI GPT-6 series, positioned below the flagship GPT-6 Astra and above the fast GPT-6 Luna. It is suitable for demanding professional work, agency coding, business workflow automation and computer use, and is particularly good at long-span software engineering tasks in real code bases. It delivers near Astra-level reliability at a fraction of the cost and continues Astra’s clear, concise communication style in technical and programming conversations.
