The honest brief
Marqo
Bundles embedding generation, storage, and retrieval behind one API and can train a model on your own catalog — no separate embedding pipeline to wire up.
- Generates and stores embeddings in-engine
- Native multimodal (text + image) search
- Turnkey ecommerce platform integrations
- Backed by Lightspeed and Blackbird
- Open-source engine is deprecated, no longer updated
- No public pricing; commercial product is sales-led
- Scope narrowed toward ecommerce search
Milvus
Storage/compute split plus DiskANN make it the most robust open-source choice at billion-vector scale.
- Scales to billion-vector deployments
- Storage/compute separation
- Many index types (HNSW, IVF, DiskANN) + GPU
- Mature project with a large community
- Operationally heavy to self-host
- Overkill for small workloads
- Performance hinges on data quality
- Higher latency than Qdrant at p50
