Step 1 of 3
Larkspur’s assistant comes in two tiers: a small model and a large one, both reading the same retrieved documents. A small answer costs 0.2 of a large one, from a real price list below; from here on costs are in large answers (1 each). The tiers are illustrations written for this site, not measured models. Before you run them:
Anthropic lists Claude Haiku 4.5 at $1 per million input tokens and $5 per million output tokens, and Claude Opus 4.5 at $5 and $25: the smaller model costs a fifth as much per token, in and out. Source: platform.claude.com (checked 2026-10-21)
