vramPaddingSize

Get Signature

get vramPaddingSize(): number;

Defined in: bindings/Llama.ts:295

VRAM padding used for memory size calculations, as these calculations are not always accurate. This is set by default to ensure stability, but can be configured when you call getLlama.

See vramPadding on getLlama for more information.

Returns

number

Methods

dispose()

dispose(): Promise<void>;

Defined in: bindings/Llama.ts:170

Returns

Promise<void>

---

getVramState()

getVramState(): Promise<{
  total: number;
  used: number;
  free: number;
  unifiedSize: number;
}>;

Defined in: bindings/Llama.ts:305

The total amount of VRAM that is currently being used.

unifiedSize represents the amount of VRAM that is shared between the CPU and GPU. On SoC devices, this is usually the same as total.

Returns

Promise<{ total: number; used: number; free: number; unifiedSize: number; }>

---

getSwapState()

getSwapState(): Promise<{
  maxSize: number;
  allocated: number;
  used: number;
}>;

Defined in: bindings/Llama.ts:330

Get the state of the swap memory.

maxSize - The maximum size of the swap memory that the system can allocate. If the swap size is dynamic (like on macOS), this will be Infinity.

allocated - The total size allocated by the system for swap memory.

used - The amount of swap memory that is currently being used from the allocated size.

On Windows, this will return the info for the page file.

Returns

Promise<{ maxSize: number; allocated: number; used: number; }>
