1-Click SeedVR 2.5 — Release Notes (v1.9.58b)

Everything new since v1.9.57b.

v1.9.58b — FP8 model crash fix, Send Logs wiring

Fixed: FP8 model crash (critical)

  • Runs with an FP8 DiT model (seedvr2_ema_*_fp8_e4m3fn.safetensors) crashed
    with RuntimeError: Promotion for Float8 Types is not supported, attempted to promote Float and Float8_e4m3fn.
  • Root cause: CustomRMSNorm deliberately skipped the dtype cast for FP8
    weights, so F.rms_norm(float_input, fp8_weight) hit PyTorch's unsupported
    float8 promotion. CustomLayerNorm already handled this correctly.
  • Fixed in both the 3B and 7B model paths: the norm weight is now always
    cast to the activation dtype (FP8 → fp16/bf16 cast is fully supported).
  • Verified by reproducing the exact crash synthetically before the fix and
    confirming clean output afterwards, plus regression checks for the
    GGUF (Q8) fast path.

Fixed: Send Logs button on unhandled-exception dialog

  • The error dialog shown for GUI-internal unexpected exceptions had a
    Send Logs button that was never connected — clicking it did nothing.
    It is now wired to the background log-email flow, so every error path
    (processing failures and internal exceptions) can report by mail.
  • The mail pipeline was live-tested end-to-end over SMTP.

Notes for users seeing old error screenshots

  • The "Send Logs" button exists on the processing-failure dialog since
    v1.9.48b — screenshots without it come from older releases; updating
    fixes that.
