Python:

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",

)

# List all models
models = client.models.list()
for model in models:
    print(f"{model.id} ({model.owned_by})")

# Get a specific model
model = client.models.retrieve("gpt-4o")
print(f"Context length: {model.context_length}")

JavaScript / TypeScript:

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "YOUR_API_KEY",
  baseURL: "https://api.universal-ai.dev/v1",

for (const model of models.data) {
  console.log(`${model.id} (${model.owned_by})`);
}

// Get a specific model
const model = await client.models.retrieve("gpt-4o");
console.log(model);
