|  `created`     | `number` | Total `createBuffer` calls observed since instrumentation began.                                      | [src/batteries/llm/chat\_common/gpu\_budget.ts:150](https://github.com/NHTIO/ADK/blob/v1.20260713.1/src/src/batteries/llm/chat_common/gpu_budget.ts#L150) |
|  `destroyed` | `number` | Total `buffer.destroy()` calls observed.                                                              | [src/batteries/llm/chat\_common/gpu\_budget.ts:152](https://github.com/NHTIO/ADK/blob/v1.20260713.1/src/src/batteries/llm/chat_common/gpu_budget.ts#L152) |

|  `liveBytes` | `number` | Currently-live buffer bytes (the number that climbs as the freelist retains larger working sets).     | [src/batteries/llm/chat\_common/gpu\_budget.ts:156](https://github.com/NHTIO/ADK/blob/v1.20260713.1/src/src/batteries/llm/chat_common/gpu_budget.ts#L156) |
|  `peakBytes` | `number` | Peak live bytes seen — the high-water-mark that, against [GpuBudget](GpuBudget.md), predicts the OOM. | [src/batteries/llm/chat\_common/gpu\_budget.ts:158](https://github.com/NHTIO/ADK/blob/v1.20260713.1/src/src/batteries/llm/chat_common/gpu_budget.ts#L158) |
