Class LlmPricing

java.lang.Object

org.mockserver.llm.cost.LlmPricing

public final class LlmPricing
extends Object

Estimated cost calculation for LLM API usage.

A pure lookup over a pricing table keyed on (provider, model) with input/output rates in USD per million tokens. Returns null for an unknown model so callers can distinguish "free/known-zero" from "unpriceable".

Kept in sync with the dashboard pricing table mockserver-ui/src/lib/llmPricing.ts — the prefixes, ordering, and rates here mirror that file. When refreshing rates, update both.

Pricing source / freshness: rates are public provider list prices captured 2025-Q4. They WILL drift — treat any total as an estimate, not an invoice. There is no automated drift check. Sources: Anthropic (anthropic.com/pricing), OpenAI (openai.com/api/pricing), Gemini (ai.google.dev/pricing).
