# 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 - Removing retired or shut-down models from the selectable model lists ## 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. - Write every per-token price as `<USD per MTok>e-6` (`0.1e-6`, not `1e-7`). - 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. ### Retiring a Selectable Model - Confirm the shutdown or retirement on the provider's official lifecycle page. - Remove the model from the selectable arrays in `packages/shared/src/server/llm/types.ts` so the model picker stops offering it. - Keep its entry in `default-model-prices.json` for historical cost lookups. - Do not reorder the arrays; if the first (default) entry retires, the next entry becomes the default. ### 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. ## Reference Map | Topic | Read this when | File | | ------------------------------- | ------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------- | | Schema and tier rules | You need the entry shape or pricing-tier invariants | [references/schema-and-tiers.md](references/schema-and-tiers.md) | | Provider sources and price keys | You need official pricing URLs, per-token conversion, or provider-specific usage keys | [references/provider-sources-and-price-keys.md](references/provider-sources-and-price-keys.md) | | Provider usage-key matrix | You are adding or changing OpenAI, Gemini, Anthropic, or Bedrock usage keys | [references/provider-usage-key-matrix.md](references/provider-usage-key-matrix.md) | | Match patterns | You are editing `matchPattern` regexes or provider coverage | [references/match-patterns.md](references/match-patterns.md) | | Workflow and validation | You are applying the end-to-end edit process or checking common mistakes | [references/workflow-and-validation.md](references/workflow-and-validation.md) | | Automated audit mode | You are running a scheduled/default-price audit and need CI-safe edit rules | [references/automated-audit.md](references/automated-audit.md) | | Audit memory | You need optional per-model context retained from a useful prior automated audit | [references/model-audit-memory.md](references/model-audit-memory.md) | ## Deterministic Helpers - Pricing file validator: `node .agents/skills/add-model-price/scripts/validate-pricing-file.mjs` - Match-pattern tester: `node .agents/skills/add-model-price/scripts/test-match-pattern.mjs --model <modelName> --accept <sample...> --reject <sample...>` - Direct regex tester: `node .agents/skills/add-model-price/scripts/test-match-pattern.mjs --pattern '(?i)^(openai/)?(gpt-4o)$' --accept gpt-4o openai/gpt-4o --reject gpt-4o-mini`
