About Pricing Update
FlowDown is scheduled to become free this year. With growing community support and feature maturity, maintenance costs have decreased, allowing us to operate more efficiently. Before this transition, prices will be reduced in phases. All core chat features will remain free, with subscription fees applying only to future personalization options.

Special Notes
FlowDown is designed for users who want full control over their AI models and are willing to configure them manually.
Every model behaves differently based on its capabilities, deployment method, and hardware resources. You are responsible for configuring and testing each model you use. FlowDown provides the tools and interfaces—you provide the configurations.
For bulk management, FlowDown supports importing and exporting model configurations (.fdmodel files). You can script the generation of configuration files and import them all at once. Join our Discord to discuss setups, but remember: community advice doesn't replace your own testing.
