OpenAI Completions Usage API Extended Example

# OpenAI Completions Usage API Extended Example For most of our users, the [default usage and cost dashboards](https://platform.openai.com/usage) are sufficient. However, if you need more detailed data or a custom dashboard, you can use the Completions Usage API. This notebook demonstrates how to retrieve and visualize usage data from the OpenAI Completions Usage API and Costs API. We'll: - Call the API to get completions usage data. - Parse the JSON response into a pandas DataFrame. - Visualize token usage over time using matplotlib. - Use grouping by model to analyze token usage across different models. - Display model distribution with a pie chart. We also include placeholders for all possible API parameters for a comprehensive overview.
