The short version

  • Each has a real cost: Milvus vector dimensions are capped at 32,768; Poe points-based pricing makes cost per message hard to predict across models.
  • They diverge on capability: Milvus covers Billion-scale vectors, Poe covers Multi-model chat.
  • Prices and features above were last checked on 30 August 2026.

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

Poe

  • Points-based pricing makes cost per message hard to predict across models.
  • Heavy usage of top-tier models can exhaust points quickly on lower plans.
  • No native fine-tuning or persistent long-term memory across bots.
  • Custom bots are limited to prompt engineering rather than full agent tooling.
