1-Click SeedVR 2.5 — Release Notes (v1.9.59b)

Everything new since v1.9.58b.

v1.9.59b — GPU-aware attention, BlockSwap safety, Split View fix

Fixed: sageattn_3 crash on non-RTX-50 GPUs (critical)

  • Selecting sageattn_3 on anything other than a Blackwell GPU
    (RTX 50xx) crashed at runtime — the SageAttention package imports fine
    on RTX 30/40 cards, so the old import-only check passed while the kernel
    could not run.
  • The attention mode is now validated against the actual GPU
    architecture    : RTX 40 → automatic fallback to sageattn_2, AMD / Intel /
    CPU-only machines → SDPA. A second kernel-level safety net guarantees
    the fallback even if a mode slips through.

New: attention options filtered by detected GPU

  • At startup the hardware probe result now drives the settings panel:
    attention modes the detected GPU cannot run are greyed out (with a
    tooltip explaining why) and an invalid saved selection is moved to the
    best mode the GPU supports.
    • RTX 50xx: sdpa, flash_attn_2, sageattn_2, sageattn_3
    • RTX 30/40: sdpa, flash_attn_2, sageattn_2
    • GTX 10/20, AMD, Intel, CPU: sdpa only
    • flash_attn_3 stays disabled everywhere (the Hopper FA3 package is not
      part of the shipped Python bundle).

Fixed: BlockSwap without an offload device

  • Runs with blocks_to_swap > 0 no longer abort with
    "dit_offload_device is invalid": the CLI now auto-sets the DiT offload
    to CPU at startup, in Auto Tune, in every OOM retry step, and rebuilds
    a cached context when swap is enabled mid-run.
  • In the GUI, enabling blocks_to_swap or swap_io_components
    automatically switches the DiT / VAE / tensor offloads to CPU.

Fixed: Split View "does nothing"

  • Split View now opens a synchronized dual-video comparison for video
    outputs (previously it dead-ended with a tiny corner toast).
  • When there is nothing to compare yet, a persistent status-bar message
    and a clear warning are shown instead of silence.

Improved: failure headlines

  • The error dialog headline no longer shows the generic
    "CUDA kernel errors might be asynchronously reported…" boilerplate —
    it now surfaces the real error line.

Other

  • Tile debug row is labelled "(TEST)" with a warning note underneath
    so it is not enabled accidentally.
  • UI language is fully English again — leftover localized tooltips were
    translated and the whole codebase scanned clean.
