@plurnk/plurnk-models

A build-time-vendored snapshot of model metadata — context window + per-token pricing — sourced from models.dev. Consumed by plurnk-providers and clients.

Fallback only — live data wins

This snapshot is a last resort, never a primary source. A backend's probed context window and a provider's fetched per-token pricing are ground truth and can change; a vendored snapshot must never shadow them — especially cost. Consumers resolve in this order:

env override  →  live probe / live pricing fetch  →  THIS catalog  →  null

The catalog only fills the gap for a known cloud model whose endpoint doesn't self-report (e.g. a relay model behind openrouter). A local model (macher.gguf on llama-server) is a deliberate miss — the probe owns that.

Use

import { lookup } from "@plurnk/plurnk-models";

const info = lookup("openrouter", "anthropic/claude-sonnet-4");
// → { contextWindow: 1000000, cost: { inputPer1M: 3, outputPer1M: 15, cacheReadPer1M: 0.3, cacheWritePer1M: 3.75 } }
// miss → null

provider is the plurnk provider name (the alias-cascade segment); model is the provider-native id (for relays, publisher/model). catalogSnapshot() returns the whole read-only map for a client's model picker.

Data

Pruned to the two fields plurnk uses, across plurnk's supported providers only (~620 models, ~64 KB). Four provider names diverge from models.dev's ids (together→togetherai, fireworks→fireworks-ai, cloudflare→cloudflare-workers-ai, ollama→ollama-cloud); the rest are identity.

No network at install or runtime — the snapshot is committed. Refresh on the release cadence:

npm run generate   # fetch models.dev/api.json → prune → src/catalog.json
