OpenAI: GPT-5.6 Terra Pro

The OpenAI GPT-5.6 Terra Pro is a powerful AI model capable of handling text, images, and files, with an extensive context length of 1,050,000 tokens and the ability to reason and process input data effectively. While it supports tools for enhanced functionality, structured output generation remains unsupported. At $2.5 per million input tokens and $15 per million output tokens, this model may be costly for projects requiring significant computational resources. Given its current lack of independent benchmark coverage, users should consider the GPT-5.6 Terra Pro when they need robust reasoning capabilities across multiple modalities and are willing to invest in a premium solution.
