Open Charts

Open Charts gives you a more detailed view of your OpenAI usage so you can understand where consumption is coming from and how it changes over time. After you enter your OpenAI API key, it displays usage across several time windows—including the last 7, 14, and 30 days, as well as the last 2 and 3 months—with both total cost and approximate activity.

The dashboard breaks your usage into clear categories: Images, Chat, Embeddings, and Instruct models. For each category and timeframe, you can quickly see how much you spent and the approximate usage amount, along with an average daily figure. This makes it easier to spot spikes, compare periods, and manage costs with more context than a single aggregate number.

Open Charts is a good fit for developers and teams that want lightweight visibility into their API spending and usage patterns. If you’re monitoring multiple model types (rather than only one endpoint or feature), the category breakdown helps you identify which areas are driving usage.

Pricing or paid plans aren’t provided in the available information—Open Charts focuses on viewing and tracking your OpenAI API usage after you supply your API key.

What does Open Charts track?

It tracks OpenAI usage across four categories: Images, Chat, Embeddings, and Instruct models, showing total cost and approximate usage for selected timeframes.

What information do I get for each usage category?

For each category (Images, Chat, Embeddings, Instruct models) and timeframe, you’ll see the cost incurred and an approximate usage amount, plus an average daily figure.

Does Open Charts show a trend over time or only one snapshot?

It shows multiple time windows, including an average-per-day metric, so you can compare how usage and cost change across periods.

Is Open Charts free to use?
