What are Molmo 2 and OLMo 3.1?

Molmo 2 is a state-of-the-art vision-language model designed for image and video understanding. It excels at object tracking, pointing, and multi-frame reasoning, outperforming many proprietary models on vision-language benchmarks.

OLMo 3.1 is AllenAI's open language model family with full transparency into training data and model development. The Instruct variant is optimized for chat and instruction-following, while the Think variant provides extended reasoning capabilities for complex problem-solving tasks.

Examples

Basic Q&A

puter.ai.chat("Explain the benefits of open-source AI models",
  { model: 'allenai/olmo-3.1-32b-instruct' }
);

Complex Reasoning

puter.ai.chat("A farmer needs to cross a river with a wolf, a goat, and a cabbage. The boat can only carry the farmer and one item. If left alone, the wolf will eat the goat, and the goat will eat the cabbage. How can the farmer get everything across safely?",
  { model: 'allenai/olmo-3.1-32b-think' }
);

Image Analysis

puter.ai.chat(
  "What do you see in this image?",
  "https://assets.puter.site/doge.jpeg",
