OpenAI: GPT-5.6 Sol Pro
The OpenAI GPT-5.6 Sol Pro is designed for handling diverse input modalities including text, files, and images, with an expansive context length of 1,050,000 tokens, making it suitable for complex tasks that require deep understanding and analysis. It supports reasoning and tools integration, enabling more sophisticated problem-solving capabilities. Given its high price point at $2.0 per million input tokens and $10.0 per million output tokens, the GPT-5.6 Sol Pro is best suited for organizations with substantial budgets willing to invest in advanced AI solutions that can process extensive data volumes and deliver detailed outputs. However, with no independent benchmark coverage yet, its performance remains unproven compared to other models.
