Sample code and API for Llama 2 13B Chat
OpenRouter normalizes requests and responses across providers for you.
OpenRouter provides an OpenAI-compatible completion API to 294 models & providers that you can call directly, or using the OpenAI SDK. Additionally, some third-party SDKs are available.
In the examples below, the OpenRouter-specific headers are optional. Setting them allows your app to appear on the OpenRouter leaderboards.
Using the OpenAI SDK
import OpenAI from "openai"
const openai = new OpenAI({
baseURL: "https://openrouter.ai/api/v1",
apiKey: "<OPENROUTER_API_KEY>",
defaultHeaders: {
"HTTP-Referer": "<YOUR_SITE_URL>", // Optional. Site URL for rankings on openrouter.ai.
"X-Title": "<YOUR_SITE_NAME>", // Optional. Site title for rankings on openrouter.ai.
}
})
async function main() {
const completion = await openai.chat.completions.create({
model: "meta-llama/llama-2-13b-chat",
messages: [
{
"role": "user",
"content": "What is the meaning of life?"
}
]
})
console.log(completion.choices[0].message)
}
main()
