OpenAI: GPT-5.6 Luna

GPT-5.6 Luna from OpenAI is designed to handle text, image, and file inputs within a context length of 1,050,000 tokens, making it suitable for complex multi-modal tasks. The model supports reasoning and tools integration, enhancing its utility in various applications. However, structured output support is not provided, limiting certain types of data processing requirements. Given its pricing at $1.0 per million input tokens and $6.0 per million output tokens, GPT-5.6 Luna may be cost-effective for projects requiring significant text or multi-modal handling but lacks independent benchmark validation to date. It should be considered by users prioritizing multi-modal capabilities and tool integration within a budget-conscious framework.
