Add Model Price

Use this skill for model pricing changes in worker/ and shared LLM type updates in packages/shared/.

When to Apply

Editing worker/src/constants/default-model-prices.json
Editing packages/shared/src/server/llm/types.ts
Adding a new priced model
Updating provider prices, cache pricing, or tier conditions
Expanding regex coverage for Bedrock, Vertex, Azure, or provider-prefixed model names
Auditing default model prices for stale, missing, or unmatched provider pricing
Auditing official provider docs for newly released major models that should receive default pricing and, when appropriate, selectable-model coverage

Quick Start Checklist

Adding a New Model

Gather official pricing from the provider documentation.
Generate a lowercase UUID for the model entry.
Create a matchPattern that covers supported provider formats.
Add at least one default pricing tier.
Map every supported semantic usage bucket to the provider aliases Langfuse may persist.
Insert the pricing entry into worker/src/constants/default-model-prices.json.
Update packages/shared/src/server/llm/types.ts if the model should be selectable in playground or evaluation flows.
Validate the JSON after editing.

Updating an Existing Model

Update the relevant prices, keys, tiers, or regexes.
Refresh updatedAt to today's ISO-8601 timestamp.
Validate the JSON after editing.
