About Docs
Vanna 2.0 is an open-source, user-aware AI agent framework that connects large language models (LLMs) to databases. At its core, it allows developers to connect tools to an LLM, enabling the agent to run SQL queries, generate charts, or perform custom functions. The framework features Tool Memory, which learns from successful interactions and improves over time by saving query patterns and adapting them to similar questions. It also enforces granular permission controls, ensuring each user has specific access rights. Vanna can be used as a self-hosted open-source solution or upgraded to managed cloud plans for larger teams.

FAQ
What happens if I exceed my daily limits?
Daily throughput limits reset every 24 hours. If you exceed your limit, requests will be rate-limited until the next reset. You can upgrade to a higher tier at any time for immediate access to higher limits.
Can I start with the open source version and upgrade later?
Yes! All tiers use the same core framework. You can start self-hosting with the open source version, then seamlessly upgrade to our managed cloud platform or enterprise deployment without rewriting your code.
How does Enterprise pricing work?
Enterprise pricing is custom based on your deployment needs (on-prem, VPC, or private cloud), desired SLAs, and support requirements. Contact our sales team to discuss your specific requirements.
Do you offer annual discounts?
Yes! Annual subscriptions receive a 20% discount. Contact sales or select annual billing during checkout.
