The short version

  • Each has a real cost: Milvus vector dimensions are capped at 32,768; Pinecone reads and writes are billed on separate meters, and reads are far more expensive, at $16 to $18 per million against $4 to $4.50 for writes on Standard
  • They diverge on capability: Milvus covers Billion-scale vectors, Pinecone covers Vector similarity search.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Milvus

  • Vector dimensions are capped at 32,768
  • A collection is limited to 64 fields, 1,024 partitions and 16 shards
  • Only 1 index is allowed per field
  • Search returns at most 16,384 vectors as top-k, and nq is capped at 16,384
  • Input and output per RPC is capped at 64 MB for insert, search and query
  • VARCHAR values are limited to 65,535 characters
  • Data loaded into query nodes cannot exceed 90% of available memory
  • An instance supports at most 65,536 collections

Pinecone

  • Reads and writes are billed on separate meters, and reads are far more expensive, at $16 to $18 per million against $4 to $4.50 for writes on Standard
  • Unit prices vary by region, so the same workload costs different amounts in different places
  • The Standard plan carries a $50 monthly minimum and Enterprise $500, charged whether or not the usage reaches it
  • Enterprise pays more per unit as well as more in minimum, at $24 to $27 per million reads against Standard's $16 to $18
  • Indexes and namespaces are capped by plan, at 5 indexes on the free tier and 20 on Standard
  • RBAC and SSO require the Standard plan
