OpenAI: GPT-5.6 Terra (batch)
This AI model from OpenAI supports input through various modalities, including text, images, and files, with a large context length of 1 million tokens. It also offers tool support and reasoning capabilities, but does not provide structured output. The GPT-5.6 Terra (batch) model is priced at $1.0 per million input tokens and $6.0 per million output tokens. With a blended benchmark score of 71.1 across one independent benchmark, it may be worth considering for users who prioritize reasoning capabilities and tool support, especially given its broad input modalities.
