Frequently Asked Questions

What is the pricing model for Manifest?▾
Manifest is open-source and free to use. You only pay for the underlying LLM APIs you route requests to, making it a cost-control layer rather than a paid service itself.
How steep is the learning curve for setting up Manifest?▾
Setup is straightforward for developers familiar with APIs and routing concepts. Documentation is available as an open-source project, though implementation time depends on your infrastructure complexity.
What integrations and APIs does Manifest support?▾
Manifest routes requests across multiple LLM providers through their standard APIs. It works as a middleware layer, so it integrates with any application that can make API calls.
What are the main limitations of Manifest?▾
As an open-source tool, you're responsible for hosting and maintaining it. It focuses on routing and cost optimization rather than providing additional AI features or data processing capabilities.
Who should use Manifest?▾
Manifest is ideal for teams running multiple LLM models in production who need to optimize costs, benchmark performance across models, and maintain strict control over API usage.
