Antfly includes ML inference (Antfly Inference) at no additional cost.
Deep Dive
Chroma is a popular open-source embedding database designed for AI applications. It excels at simplicity and developer experience for vector storage and retrieval.
However, Chroma is primarily a vector-only store. If your application needs full-text search, structured queries, or production-grade distribution, you'll need additional infrastructure alongside Chroma.
Antfly provides all of these capabilities in a single binary: vector search, BM25 full-text search, document storage, and local ML inference, eliminating the need to stitch together multiple services.
