OpenAI: GPT-5.6 Sol Pro (batch)

GPT-5.6 Sol Pro from OpenAI is designed for extensive text, image, and file handling with a context length of 1 million tokens; it supports reasoning and tools integration but does not offer structured output or open weights. With capabilities in multiple modalities and reasoning, this model could be ideal for complex tasks requiring nuanced understanding and data processing across various formats. Given its robust feature set, GPT-5.6 Sol Pro is best suited for projects demanding high-context analysis and tool integration, though its unproven benchmark coverage means performance benchmarks are currently unavailable. At a cost of $1.0 per million input tokens and $5.0 per million output tokens, it's important to weigh this pricing against the specific needs of your project before shortlisting it.
