AllenAI Olmo 3 is Now Available in Puter.js

Puter.js now supports Olmo 3, giving developers access to AllenAI's open language models—completely free, no API keys required.

What is Olmo 3?

Olmo 3 is AllenAI's open language model family designed for both research and practical applications. Built with transparency and accessibility in mind, Olmo models excel at instruction-following, reasoning, and natural conversation.

Available Models

Puter.js provides access to several Olmo variants, each optimized for different use cases:

1. Olmo 3 Instruct (7B) - Instruction fine-tuned variant optimized for instruction-following, question-answering, and natural conversational dialogue

2. Olmo 3 Think (7B & 32B) - Research-oriented model designed for advanced reasoning, multi-step problem solving, and logical inference

3. Olmo 2 (32B Instruct) - Previous generation model with robust instruction-following capabilities

Examples

Simple conversation with Olmo 3 Instruct

puter.ai.chat("Explain the concept of quantum computing in simple terms",
    { model: 'allenai/olmo-3-7b-instruct' }
).then(response => {
    console.log(response);
});

Advanced reasoning with Olmo 3 Think

For complex problem-solving and multi-step reasoning, use Olmo 3 Think with streaming:

async function streamResponse() {
    const response = await puter.ai.chat(
        "Explain the process of training a large language model, from data collection to deployment",
        { model: "allenai/olmo-3-7b-think", stream: true }
    );

    for await (const part of response) {
        if(part?.reasoning)
            console.log("Reasoning:", part.reasoning);
        else
            console.log("Response:", part.text);
    }
}

streamResponse();

Question answering

puter.ai.chat("Compare the benefits and drawbacks of solar vs wind energy",
    { model: 'allenai/olmo-3-7b-instruct' }
).then(response => {
    console.log(response);
});
