What the models actually said.
The ranking is the answer; these are the words behind it. Every quote is from a recorded model answer — follow the category to read it whole.
LanceDB
LanceDB — Best for local-first, embedded, edge, or multimodal-data-heavy applications, because the open-source edition runs in-process like SQLite and can later graduate to a distributed managed deployment.
ChatGPT
Milvus
Zilliz Cloud / Milvus — Pick this for genuinely large-scale, high-throughput workloads or if you expect to grow into distributed vector infrastructure; it is powerful, but usually more system than an early startup needs.
