OpenAI: GPT-5.6 Luna Pro (batch)
GPT-5.6 Luna Pro from OpenAI is designed for handling text, images, and files with a context length of 1 million tokens. It supports reasoning and tools, making it versatile for complex tasks. However, this model does not offer structured output or open weights access. Given its pricing at $0.1 per million input tokens and $0.6 per million output tokens, it may be more suitable for projects requiring extensive text generation or multimodal processing where the cost is a secondary consideration. Until further benchmark coverage is available, users should carefully assess their needs against this model's capabilities before shortlisting it.
