    Modal's Sandbox resource allocation: on-demand burst rather than reserved

    Modal's Sandbox only uses up to 6% of the peak CPU in typical usage, as it is idle during inference and only peaks when dependencies are installed, tested, or built. The current fixed resource reservation mode is not suitable for such bursty workloads, forcing users to reserve resources for peaks and pay continuously. Modal's Sandbox adopts an on-demand burst mode, acquiring CPU and memory resources only when needed, and users pay based on actual usage, with an average cost 58% lower than the fixed reservation mode.
