ToolAssay

Cheapest AI model that can do your job

Cheapest AI model that can do your job. Describe the task (or list needed features: tools, json, reasoning, vision...), expected input/output tokens and a quality level (budget/balanced/best); get the cheapest suitable models across all major providers with estimated USD cost per call and per 1,000 calls, from live prices. POST {task, inputTokens, outputTokens}.
