• Qwen: The original Qwen 1.5 models spanning from 0.5B to 110B parameters.
• Qwen2.5: Models pre-trained on Alibaba's large-scale dataset with up to 18 trillion tokens.

Phi Series

Microsoft's Phi models are known for their efficiency and strong performance despite their relatively small size. Notable Phi models in the Ollama library include:

• Phi4: A 14B parameter, state-of-the-art open model.

Mistral Family

Mistral AI has made a name for itself with its high-performing and openly available models. The Ollama library includes several Mistral models:

• Mistral: The 7B model released by Mistral AI, updated to version 0.3.

Embedding Models

Embedding models convert texts to vectors that represent the semantic meaning of a word. The models can be used to build recommendation engines and perform clustering tasks. Several embedding models in the Ollama library include:

• nomic-embed-text: High-performing open embedding model.
• mxbai-embed-large: State-of-the-art large embedding model from mixedbread.ai.
• snowflake-arctic-embed: Text embedding model suite optimized for performance.

Choosing the Right Model

With such a diverse range of models available, selecting the right one for your specific needs can be challenging. Consider the following factors:

• Task: What specific task do you want to accomplish (e.g., text generation, code completion, image captioning)?
• Model Size: Larger models generally perform better but require more computational resources.
• Hardware: Ensure your hardware meets the minimum requirements for the chosen model.
• Tags: Use the tags in the Ollama library to filter models based on specific capabilities (e.g., "tools," "vision," "embedding").
• Community: Consult the Ollama Blog, GitHub and Discord community for recommendations and insights.
