OpenAI: GPT-5.6 Terra (batch)
The OpenAI GPT-5.6 Terra (batch) is designed to handle extensive text, file, and image inputs within a vast context of 1,050,000 tokens, making it suitable for complex tasks that require deep understanding and multi-modal data processing. It supports reasoning and tools integration, though structured output support remains unverified. This model stands with a blended benchmark score of 92.7 across three independent evaluations, particularly excelling in coding but showing moderate performance in agentic tasks. Given its price point of $1.0 per million input tokens and $6.0 per million output tokens, this model is more suited for projects requiring high context handling and multi-modal data integration where the premium cost can be justified by its robust benchmark standing across various domains.
