@graphorin/pricing ​

Bundled LLM pricing snapshot for the Graphorin framework.

@graphorin/pricing is a tiny dependency-free package that ships a representative LLM pricing catalogue, a lookupPrice(...) resolver, a snapshot-diff utility, an opt-in refreshPricing(...) hook, and the listMissingModels(...) utility used by trace audits.

The package is intentionally separate from @graphorin/observability so consumers can:

  • pin the pricing snapshot independently of the framework version,
  • ship a custom snapshot without forking the observability package,
  • decline the bundled snapshot entirely (just don't import it).

Install ​

bash
pnpm add @graphorin/pricing

Quick start ​

ts
import {
  BUNDLED_SNAPSHOT,
  calculateCost,
  lookupPrice,
} from '@graphorin/pricing';

const price = lookupPrice({ provider: 'anthropic', model: 'claude-3-5-sonnet-20241022' });
if (price !== null) {
  console.log(`Input: $${price.inputUsdPerToken} / token`);
}

const cost = calculateCost(
  {
    provider: 'openai',
    model: 'gpt-4o-2024-11-20',
    inputTokens: 1_000,
    outputTokens: 500,
  },
  BUNDLED_SNAPSHOT,
);

Refreshing ​

ts
import { refreshPricing } from '@graphorin/pricing';
import { writeFile } from 'node:fs/promises';

const snapshot = await refreshPricing({
  url: 'https://example.com/pricing.json',
});
await writeFile('./pricing.json', JSON.stringify(snapshot, null, 2));

The framework never invokes refreshPricing(...) automatically per the zero-default-telemetry policy; the operator runs it on demand.
