notapalindrome/ltx25-mlx

MLX split pack of LTX-2.5 for Apple Silicon, for use with dgrauet/ltx-2-mlx / the LTX Video Generator macOS app (ltx2Mlx backend).

You do not need to distill anything. This pack already includes:

File	Role
transformer-distilled.safetensors	Distilled DiT (8-step, CFG=1)
transformer-dev.safetensors	Dev / full DiT
ltx-2.5-22b-distilled-lora-450-bf16.safetensors	Distilled LoRA for official Dev two-stage (bundled here so Dev does not need a second gated download)
gemma4-12b-ltx-v1/ + connector.safetensors	Gemma 4 12B TE
vae_*, audio_vae, vocoder	DiffVAE + conv VAE + audio
spatial_upscaler_*, temporal_upscaler_*	Latent ×2 upscalers
duration_head.safetensors	Optional duration predictor
