LTX-2.3 10Eros v1.3 DMD — MLX int8 (q8)

Int8 (8-bit) MLX quantization of TenStrip/LTX2.3-10Eros v1.3 with the JoyAI Echo DMD distillation baked directly into the transformer, replacing the native rank-384 distilled LoRA.

Converted with mlx-forge and packaged for ltx-2-mlx — a pure-MLX port of LTX-2 for Apple Silicon.

What this is

This is a distilled-only package. The DMD distillation deltas extracted from JoyAI Echo (rank-256, reshaped from the LTX 384 1.1 distilled-LoRA shapes, audio branch sourced from the 384 1.1 distilled LoRA) were merged into the 10Eros v1.3 base at strength 1.0, producing a standalone distilled transformer. There is no dev transformer and no runtime LoRA fusion — the distillation is already in the weights.

Compared to the native 384 distilled LoRA, the DMD merge avoids the resampling-to-base drift, the conditioning drop from the latent, and the extra detail/look overwrites that the stock distilled LoRA introduces at the upscale refine stage.

Run it with --distilled. The two-stage (--two-stage, --two-stages-hq) and one-stage-dev (--one-stage) paths are not available here — they require a dev transformer, which this package intentionally omits.

What's in here

File	Size	Role
transformer-distilled-1.1.safetensors	~19.2 GB	Distilled transformer with the JoyAI Echo DMD deltas pre-fused, int8
connector.safetensors	~5.9 GB	Gemma → DiT embedding connectors
spatial_upscaler_x1_5_v1_0.safetensors	~1.0 GB	1.5× neural latent upscaler
spatial_upscaler_x2_v1_1.safetensors	~950 MB	2× neural latent upscaler (stage-2 refine)
vae_encoder.safetensors / vae_decoder.safetensors	~1.4 GB	Video VAE (8× temporal, 32× spatial)
temporal_upscaler_x2_v1_0.safetensors	~250 MB	2× temporal upscaler
vocoder.safetensors	~250 MB	BigVGAN v2 vocoder + BWE generator
audio_vae.safetensors	~106 MB	Audio VAE decoder

Quantization: int8, group size 64, applied only to nn.Linear inside transformer_blocks. AdaLN, projections, connectors, VAE and vocoder remain bf16 (MLX cannot quantize Conv layers).

Text encoder: Gemma 3 12B is not bundled — ltx-2-mlx loads it separately via mlx-lm.

mlx-forge may also drop ltx-2.3-22b-distilled-lora-384*.safetensors (~7.1 GB each) into this directory as "shared" LoRA components. They are unused in a distilled-only package — nothing fuses them (there is no dev transformer, and --distilled never loads a LoRA). Safe to delete; also remove them from the lora list in split_model.json.

Usage

Requires ltx-2-mlx on Apple Silicon.

# Text-to-video (distilled two-stage: half-res → upscale → full-res refine)
ltx-2-mlx generate \
  --model /path/to/ltx-2.3-10eros-v1.3-dmd-mlx-q8 \
  --prompt "your prompt" \
  --distilled \
  -H 480 -W 704 -f 97 -o out.mp4

# Image-to-video — add --image
ltx-2-mlx generate \
  --model /path/to/ltx-2.3-10eros-v1.3-dmd-mlx-q8 \
  --prompt "animate this" \
  --distilled --image photo.jpg -o out.mp4

Default distilled flow is the usual 8/4-step upscale schedule. Experiment with other sigmas or any Euler / LTX-compatible sampler — no custom loading or sampling is needed. On 32 GB Macs add --low-ram for block-streamed inference; q8 fits 16 GB with --low-ram.

Conversion provenance

1. The JoyAI Echo DMD LoRA was merged into the 10Eros v1.3 bf16 base at per-layer strength 1.0 (alpha ÷ actual rank) to produce a distilled bf16 checkpoint:

   uv run ~/mlx-forge/scripts/merge_lora.py
   # LoRA:   LTX2.3_DMD_reshaped_r256.safetensors
   # → /Volumes/Storage/10Eros-v1.3-distilled-dmd-bf16.safetensors
   

2. Distilled variant + all shared components + upscalers, quantized to int8:

   uv run mlx-forge convert ltx-2.3 --variant distilled-1.1 \
     --checkpoint /Volumes/Storage/10Eros-v1.3-distilled-dmd-bf16.safetensors \
     --quantize --bits 8 \
     --spatial-upscaler x2 x1.5 --temporal-upscaler x2 \
     --output models/ltx-2.3-10eros-v1.3-dmd-mlx-q8
   

No dev variant is added — this package is distilled-only by design.
