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

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.
