OpenAI: gpt-6.1-terra-pro
GPT-6.1 Terra Pro is an OpenAI model listed in the manufacturer's model catalog. The available material confirms little beyond its presence in that list: one source verified only two pricing rows from OpenAI's own page and explicitly confirmed no capability claims, no context window, no maximum output size, and no usage conditions for this Pro variant. Because of that gap, the Pro model's strengths and intended tasks cannot be stated with confidence. The closest documented reference point is the non-Pro GPT-6.1 Terra, a mid-tier model in OpenAI's GPT-6 series released on October 26, 2026, with a 1.1M token context window. That model is described as suited to everyday agentic work, coding, and writing, with particular strength in reading screenshots and on-screen content, and is recommended as the default for high-volume document processing, form entry, and computer-use work. Those details describe GPT-6.1 Terra, not GPT-6.1 Terra Pro, and should not be transferred to the Pro variant. Anyone evaluating GPT-6.1 Terra Pro should check OpenAI's current model documentation for verified specifications before relying on it for production workloads.
