The leaderboard problem

Rankings are generic, not based on your specific needs

Leaderboards measure general preference, and the podium moves monthly. Neither fact is about your work.

  • A leaderboard says what people liked on average.
  • It cannot say what clears your bar, on your requests, at what price.
  • The Request Compiler ranks one thing: measured performance on your kind of work, re-verified on every release.

The Request Compiler

Two minutes of work. Then it's handled.

Two lines change: the base URL and the key. Everything after is The Request Compiler's job.

  • The bar is registered before any test. What cannot clear it never serves.
  • Unmeasured work serves the model you named, at pass-through price.
  • Both models and both prices on every receipt. The fee is 25% of verified savings; served as asked has no markup.
openai.ts

import OpenAI from 'openai';

const openai = new OpenAI({

baseURL: `${process.env.FINEST_GATEWAY_URL}/gateway/openai/v1`,

apiKey: process.env.FINEST_API_KEY,

});

// model stays 'your-current-model'

Two minutes from now, your next request costs less.

Swap two lines and read the first receipt. No savings, no fee.
