The short version

  • Each has a real cost: Factory the $100 per month Plus tier only grants about 5 times the usage of the $20 Pro tier, so usage scales sub-linearly with price, as of August 2026.; LangSmith usage beyond the included trace allotment is billed in LangChain Compute Units at $1.50 per LCU and Storage Units at $1.00 per LSU, an unfamiliar metering unit compared to flat per-seat pricing, as of August 2026.
