Same weights don't always mean identical outputs: quantization, context limits and serving stacks can change quality, especially for tool calling. Prices are USD per 1M tokens; hyperscaler prices are for the reference region shown.

Monthly cost estimate

Anthropic $1,000/mo

Cache hits use each provider's cached-input price where it has one. Cache write costs aren't included.
