OpenAI: GPT-5.6 Sol (batch)

GPT-5.6 Sol (batch) from OpenAI is designed for extensive text, image, and file processing with a context length of 1,050,000 tokens. It supports reasoning and tools integration but does not offer structured output or open weights. The model excels in handling diverse input modalities, making it suitable for complex tasks that require understanding across various data types. While boasting a blended benchmark score of 99.3 from three independent sources, GPT-5.6 Sol (batch) may be more appropriate for those willing to invest in its higher pricing-$2.5 per million input tokens and $15 per million output tokens-especially if the extensive context length and broad input capabilities are critical for your project needs.
