Pricing modelPaid Free
PricingStarter plan is free with $30/month compute credits. Team plan is $250/month plus compute. Enterprise plan is custom. Compute is billed per second for CPU, GPU, and memory with no charges for idle time. Personal: Free during early access. Unlimited memories, all agents with separate memories, no card required. Enterprise: On request, set up by the team for departmental organization with cross-department sharing and direct support.

  • Pay only by the second with no idle charges
  • Programmatically create millions of concurrent sandboxes
  • Understands what changed, when it was true, and where it belongs - beyond vector database similarity
