OpenAI: GPT-5.6 Sol Pro
GPT-5.6 Sol Pro from OpenAI is designed for handling text, file, and image inputs within a context length of 1,050,000 tokens. It supports reasoning and tools integration, making it suitable for complex tasks that require both comprehension and external data interaction. While the model lacks structured output capabilities, its ability to process multiple modalities and reason about content is robust. Considering its pricing at $5.0 per million input tokens and $30.0 per million output tokens, GPT-5.6 Sol Pro might be more suited for users who can justify higher costs with specific needs that benefit from extensive reasoning and tool integration, despite the absence of independent benchmark data to quantify performance.
