The short version

  • Each has a real cost: Letta the Developer API plan charges $0.10 per active agent per month plus $0.00015 per second of tool execution on top of a $20 per month base and pay-as-you-go LLM usage, as of August 2026.; Browser Use billing stacks two separate meters at once: per-token model usage plus $0.02 per hour of browser time, metered by the minute, so cost depends on both reasoning length and session duration, as of August 2026.
