OpenAI: GPT-5.6 Terra (batch)

The OpenAI GPT-5.6 Terra is a batch model that accepts input from text, image, and file modalities, with a context length of up to 1.05 million tokens. It supports tools and reasoning capabilities, but does not provide structured output. This model may be suitable for users who require the ability to handle large inputs across multiple modalities. At $1.00 per million input tokens and $6.00 per million output tokens, it is a more expensive option compared to others with similar benchmark standings. Despite having a blended benchmark score of 71.1 across one independent benchmark, its performance in other areas remains untested due to missing or low coverage in the available data.
