OpenAI: GPT-5.6 Luna

The OpenAI GPT-5.6 Luna is a multi-modal AI model that can process text, images, and files with a context length of up to 1 million tokens. It also supports tools and reasoning capabilities, but does not provide structured output. This model may be suitable for users who require a high-context understanding and want to integrate multiple input modalities. Its price point of $0.2 per million input tokens and $1.2 per million output tokens is relatively steep compared to other models on the market. With a blended benchmark score of 62.3 across one independent benchmark, it performs decently but may not be the top choice for users seeking exceptional performance. As such, it may be worth considering alongside other options for those with specific requirements and a budget to match.
