Class UniversalRope

constructor

• new UniversalRope(
      dims: number,
      traditional: boolean,
      base: number | null,
      scale: number,
      freqs: MlxArray | null,
      preScale: number,
      preScaleAlways: boolean,
  ): UniversalRope

  Parameters

  • dims: number
  • traditional: boolean
  • base: number | null

    Base for native fast_rope; null when freqs supplies the table.

  • scale: number

    fast_rope scale (1/factor for "linear", else 1).

  • freqs: MlxArray | null

    Precomputed frequency table (llama3/yarn/longrope/proportional).

  • preScale: number

    Pre-rope input scale on x[..., :dims] (yarn mscale / su scale).

  • preScaleAlways: boolean

    Apply preScale even when it is exactly 1.0 (SuScaledRoPE does; Yarn skips when mscale == 1.0).

  Returns UniversalRope

apply

• apply(x: MlxArray, offset: number): MlxArray

  Parameters

  • x: MlxArray
  • offset: number

  Returns MlxArray

applyDynamic

• applyDynamic(x: MlxArray, offsetArr: MlxArray): MlxArray

  Per-row array-offset variant (batched decode under left-padding: each row's REAL position rides an int32 [B] array — the scalar offset would mis-position every padded row by its pad amount). Same math as apply; only the offset spelling differs.

  Parameters

  • x: MlxArray
  • offsetArr: MlxArray

  Returns MlxArray

dispose

• dispose(): void

  Returns void
