anthropic:claude-haiku-3

Added March 7, 2024

Claude Haiku 3 is Anthropic's cheapest model. It's designed to be fast, though not necessarily that intelligent.

Usage

import OpenAI from "openai";

const client = new OpenAI({
    baseURL: "https://api.tributary.cc/openai/v1",
    apiKey: "<TRIBUTARY_API_KEY>",
});

const completion = await client.chat.completions.create({
    model: "anthropic:claude-haiku-3",
    messages: [
        { role: "user", content: "Hello!" }
    ],
});

console.log(completion.choices[0].message.content);

const response = await fetch(
    "https://api.tributary.cc/openai/v1/chat/completions",
    {
        method: "POST",
        headers: {
            "Authorization": "Bearer <TRIBUTARY_API_KEY>",
            "Content-Type": "application/json",

                { role: "user", content: "Hello!" }
            ],
        }),
    }
);

const data = await response.json();
console.log(data.choices[0].message.content);
