# Interface: GpuBudget

Defined in: [src/batteries/llm/chat\_common/gpu\_budget.ts:37](https://github.com/NHTIO/ADK/blob/v1.20260713.1/src/src/batteries/llm/chat_common/gpu_budget.ts#L37)

A snapshot of the WebGPU device's memory budget, as reported by the adapter/device limits.

## Remarks

All sizes are bytes. `maxBufferSize` and `maxStorageBufferBindingSize` are the hard per-allocation
ceilings a single ONNX tensor buffer cannot exceed — the practical wall an over-large context window
hits first (e.g. ~4 GiB on Apple Metal). These are LIMITS, not live usage; pair with
[GpuBufferInstrument](GpuBufferInstrument.md) for live high-water-mark tracking.
