# Subscriptions vs on-demand Pay-per-second Skynet provides flexible pricing models for accessing resources, each suited for different needs. Users pay a fixed rate to access resources over a specified period with subscriptions. This model is ideal for users and AI agents with predictable resource demand as it offers consistent access. In contrast, the on-demand pay-per-second pricing model is designed for highly dynamic resource usage, allowing users to meet their consumption needs as needed and pay based on seconds. This versatility ensures that Skynet’s infrastructure adapts to varied resource demands, promoting scalable and cost-effective AI-driven applications and agents. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
