The trade-off between sleep time and test time compute is significant, especially regarding inference costs during high demand.

• Test time tokens are more expensive, influencing the overall cost strategy.
• Latency optimized inference can be ten times more costly during peak usage.
• Understanding this trade-off is essential for effective AI model deployment.

8. Predictability of queries affects the effectiveness of sleep time compute.

The success of sleep time compute is linked to how predictable the questions are based on the provided context.

• Higher predictability leads to better accuracy in responses.
• Unrelated questions to the context diminish the benefits of pre-processing.
• Future research aims to identify contexts with predictable questions for better allocation of resources.
