Hi, thanks for the question. There are specific details and criteria when it comes to refunds and credits with reservations. This document outlines the process and details:

Thanks for the question. Here are some best practices to consider when purchasing PTUs:

1. Workload Characteristics: Different workloads consume varying amounts of processing capacity. Generations require more capacity than prompts. Analyze historical token usage data or call shape estimations (input and output tokens, requests per minute) to approximate PTUs needed.
2. Traffic Patterns: A wide distribution of call shapes, including some large calls, may lead to lower throughput per PTU compared to a narrower distribution with similar average sizes.
3. Capacity Planning Tools: Utilize the Foundry calculator to size specific workload shapes and estimate the required PTUs based on input and output tokens.
4. Benchmarking: The most accurate way to determine capacity is to benchmark a deployment with a representative workload for your use case.

Thanks for the question. Here are some recommendations to track forecasted Azure spend and align it to your budgets:

1. Set Budgets & Alerts in Azure Cost Management

Create budgets for subscriptions, resource groups, or workloads and set alerts so you know when spending approaches your target.

3. Track Costs by Team or Project With Tags

Tagging resources (e.g., by cost center, environment, or app) makes it easy to report on and allocate costs accurately.
