Usage

import {
  allModels,
  providers,
  getModel,
  getProvider,
  getActiveModels,
  getModelsByProvider,
  getModelsByFamily,
  getModelsByCreator,
} from "modelpedia";

// All models (4000+)
console.log(allModels.length);

// Find a specific model
const model = getModel("openai", "gpt-4o");
console.log(model?.pricing); // { input: 2.5, output: 10, ... }

// Get all active (non-deprecated) models
const active = getActiveModels();

// List models by provider
const openaiModels = getModelsByProvider("openai");

// List models by family
const gpt4oFamily = getModelsByFamily("gpt-4o");

// List models by creator (useful for aggregators like OpenRouter)
const anthropicModels = getModelsByCreator("anthropic");

// Get provider info
const provider = getProvider("anthropic");
console.log(provider?.name); // "Anthropic"
console.log(provider?.api_url); // "https://api.anthropic.com/v1"

Per-provider imports

Import only the provider you need for smaller bundle size:

import { provider, models } from "modelpedia/openai";
console.log(provider.name); // "OpenAI"
console.log(models.length); // 151

import { models as anthropicModels } from "modelpedia/anthropic";
import { models as googleModels } from "modelpedia/google";

Available: modelpedia/openai, modelpedia/anthropic, modelpedia/google, modelpedia/mistral, modelpedia/deepseek, modelpedia/xai, and 24 more.
