Frequently Asked Questions

What is the main difference between Marqo and Milvus?

Marqo focuses on simplifying workflows with built-in ML models for on-the-fly embeddings and multimodal search, while Milvus prioritizes scalability and performance with advanced indexing options for large-scale similarity search.

Which is better for small teams?

Marqo is better for small teams due to its streamlined API and reduced setup complexity, whereas Milvus may require more resources and expertise to configure optimally.

Can I migrate from Marqo to Milvus?

Yes, but migration would require reworking embedding workflows (Marqo's on-the-fly generation vs. Milvus's precomputed embeddings) and adjusting indexing strategies.

What are the pricing differences?

Both tools are open source with no paid tiers. Marqo and Milvus offer free, unlimited usage, but enterprise support options exist separately (Zilliz for Milvus, not explicitly stated for Marqo).
