LangChain launches metered billing at $1.50 per compute unit
What happened
Between the May 25, 2026 and Jun 1, 2026 captures of LangChain's pricing page, Pulse recorded one change: LangSmith Engine metered billing introduced at $1.50/LCU (LangChain Compute Unit). Enterprise plan packaging updated from 'Custom Fleet packages' to 'Custom packages for Fleet, Engine, and Sandboxes'. Pulse files it as a packaging change (new add-on) with an upward direction. Pulse's latest capture (Oct 5, 2026) lists Plus at $39.
It lands 13 days after LangChain's previous change, "LangChain launches ephemeral agent sandboxes with usage-based pricing" (May 19, 2026). Before that Pulse recorded "LangChain launches LangSmith Fleet for no-code AI agent creation" (Apr 3, 2026) and "LangChain rebrands Agent Builder to Fleet across pricing tiers" (Mar 24, 2026). LangChain has been tracked since 2024-11-17.
In the same window Huggingface, Together AI, Anthropic, OpenAI and Cohere also changed their AI & Machine Learning pricing pages. Those moves are listed further down, and the Pulse Agent can compare them side by side.
