What's Changed

  • Apple Silicon Macs can now generate locally (tested on M4 Pro / 48GB — treat lower configs as a bonus, not a guarantee). Intel Macs stay API-only (no MPS backend)
  • Built-in LoRA / IC-LoRA library — browse and download from inside the app, per-adapter strength slider, or drop your own .safetensors into loras/ (local generation only)
  • Enhance: rewrites your prompt before generation (video, image, IC-LoRA). Picks up the selected LoRA/IC-LoRA's metadata, example prompts, and trigger words automatically. Runs on the local Gemma text
    encoder or via Gemini API
  • Video extend: grow a generated clip forward or backward, locally or via API
  • Image editing (Z-Image-Turbo): image-to-image editing alongside existing text-to-image, locally or via fal API
  • Base model manager in Settings: download, switch, and delete LTX model versions; option to keep the previous checkpoint after an upgrade
  • First-run setup now shows exact download sizes per file and a total
  • Experimental "Diffusion Stage Cache" (Settings, NVIDIA/CUDA only, off by default) — can speed up fast generations by skipping redundant reload work

Bug Fixes

  • Leaving a project mid-generation and returning no longer loses the result
  • Fixed visible artifacts/glitches on upscaled videos
  • Fixed a file-path bug that stopped some local video/image files from loading

Mac note

The app checks for ~15GB free RAM (not total) at launch. If a capable Apple Silicon Mac shows API-only mode, close memory-heavy apps (browsers are the usual culprit), then quit and relaunch — freeing RAM while the app stays open won't retrigger the check.
