Both models have a 1,050,000-token context in the live catalogue. It lists text, image, and file input, with text output. Official documentation describes Sol for complex coding and agentic workflows and Luna for focused, high-volume tasks. Those are maker use-case descriptions; test your own prompts before assigning work by tier.
A practical selection rule
Start with Luna for repeatable, high-volume tasks where it meets your output requirements. Use Sol when the task’s reasoning or coding needs justify the higher token rate. If you have a production prompt, compare both on the same input and track the full input/output usage, including cache events.
