OpenAI: GPT-5.6 Terra

GPT-5.6 Terra from OpenAI is designed to process text, images, and files with a vast context length of 1,050,000 tokens and supports reasoning and external tools for enhanced functionality. This model excels in handling complex tasks but comes at a cost; it's priced at $1.0 per million input tokens and $6.0 per million output tokens. Those seeking robust AI capabilities across multiple modalities and needing the flexibility to integrate external tools should consider GPT-5.6 Terra, especially if benchmark scores are highly important. With a blended score of 92.7 from three independent benchmarks, it offers strong performance; however, its high price might be a deterrent for smaller projects or those prioritizing cost-effectiveness.
