  • 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

How to Read This Skill

  • Use this SKILL.md as the high-level workflow and helper index.
  • Open only the specific reference file that matches the task.

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.
  • 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.
