What is TAESD?

TAESD is very tiny autoencoder which uses the same "latent API" as Stable Diffusion's VAE*. TAESD can decode Stable Diffusion's latents into full-size images at (nearly) zero cost. Here's a comparison on my laptop:

TAESD is compatible with SD1/2-based models (using the taesd_* weights).

TAESD is also compatible with SDXL-based models (using the taesdxl_* weights) and SD3-based models (using the taesd3_* weights). Several non-SD models have support too.

How do I use TAESD with non-SD models?

  • For FLUX.1, use the taef1_* weights.
    • For HiDream and Z-Image (which use the same VAE as FLUX.1), you also want the taef1_* weights.
  • For FLUX.2, FLUX.3, MOSS-Image, use the taef2_* weights.
  • For Qwen Image (which uses the Wan 2.1 VAE), check TAEW2.1.
  • For Qwen Image 2.1, use the taeqi2_1_* weights (or the even-tinier taeqi2_1_tinier_* weights).
  • For Sana (dc-ae-f32c32-sana-1.0), use the taesana_* weights.

Where can I get TAESD?

What can I use TAESD for?

Since TAESD is very fast, you can use TAESD to watch Stable Diffusion's image generation progress in real time. Here's a minimal example notebook that adds TAESD previewing to the 🧨 Diffusers implementation of SD2.1.

Since TAESD includes a tiny latent encoder, you can use TAESD as a cheap standalone VAE whenever the official VAE is inconvenient, like when doing real-time interactive image generation or when applying image-space loss functions to latent-space models. You can even run TAESD on a dedicated tiny NPU for maximum efficiency.

Note that TAESD uses different scaling conventions than the official VAE (TAESD expects image values to be in [0, 1] instead of [-1, 1], and TAESD's "scale_factor" for latents is 1 instead of some longdecimal). Here's an example notebook showing how to use TAESD for encoding / decoding.

How does TAESD work?

TAESD is a tiny, distilled version of Stable Diffusion's VAE*, which consists of an encoder and decoder. The encoder turns full-size images into small "latent" ones (with 48x lossy compression), and the decoder then generates new full-size images based on the encoded latents by making up new details.

The original / decoded images are of shape 3xHxW with values in approximately [0, 1], and the latents are of shape 4x(H/8)x(W/8) with values in approximately [-3, 3]. You can clip and quantize TAESD latents into 8-bit PNGs without much loss of quality. TAESD latents should look pretty much like Stable Diffusion latents.

Internally, TAESD is a bunch of Conv+ReLU resblocks and 2x upsample layers:

What are the limitations of TAESD?

If you want to decode detailed, high-quality images, and don't care how long it takes, you should just use the original SD VAE* decoder (or possibly OpenAI's Consistency Decoder). TAESD is very tiny and trying to work very quickly, so it tends to fudge fine details. Example:

TAESD trades a (modest) loss in quality for a (substantial) gain in speed and convenience.

Does TAESD work with video generators?

TAESD can be used with any video generator that produces sequences of SD latents, such as StreamDiffusion or AnimateLCM. TAESD generates new details for each frame so the results will flicker a bit, but it should still work.

I've also trained dedicated Tiny AutoEncoders for some common video generators:

  • TAEHV, for Hunyuan Video, Hunyuan Video 1.5, Wan 2.1, Wan 2.2, Qwen Image, CogVideoX, Open-Sora 1.3, and LTX-2.
  • TAESDV, for SD1, SD2, and SVD
  • TAEM1, for Mochi 1
