| `Date`           | `string` | :heavy\_check\_mark: | UTC calendar date the row is aggregated over (YYYY-MM-DD).                                                                                                                                                                                                                                                                              | 2026-05-11               |
| `ModelPermaslug` | `string` | :heavy\_check\_mark: | Model variant permaslug (e.g. `openai/gpt-4o-2024-05-13`, `openai/gpt-4o-2024-05-13:free`). Non-default variants include a `:variant` suffix and are ranked as their own entry. The reserved value `other` denotes the aggregated row covering every model outside the daily top 50 for that date — always sorted last within its date. | openai/gpt-4o-2024-05-13 |
| `TotalTokens`    | `string` | :heavy\_check\_mark: | Sum of `prompt_tokens + completion_tokens` for the day, returned as a decimal string so 64-bit values are not truncated.                                                                                                                                                                                                                | 12345678                 |
