Real-time verified B2B data APIs.
We're working on creating a detailed video review for Letta.
Letta is recommended for developers who want to build AI agents that learn and improve over time. It’s perfect for those needing stateful, model-agnostic agents with advanced memory, ready to integrate into apps via APIs and SDKs.
Letta offers three plans: a free plan with 5,000 monthly credits, 2 agent templates, and 1 GB storage for beginners; a Pro plan at $20/month with 20,000 monthly credits, unlimited agents, 20 templates, 10 GB storage, and pay-as-you-go overage for production use; and an Enterprise plan with custom, volume-based pricing for large organizations, including advanced security, dedicated support, and BYOK. Monthly credits are used for LLM requests and tool executions, and reset every month. No trial is available, but startup discounts can be requested.
