KVAE tokenizers target multimodal generative models
The arXiv report describes audio, image and video tokenizers for text-conditioned generation.
Why it matters
Tokenizers shape the quality and efficiency of latent diffusion models, so stronger open multimodal tokenizers could affect downstream text-conditioned generation systems. The paper is relevant for teams comparing tokenizer choices across audio, image and video pipelines.
The key points
- 1.KVAE covers audio, image and video tokenization.
- 2.Authors report competitive results against several open-source frontier tokenizers.
- 3.The report includes training details, model selection methods and ablations.
A new arXiv report introduces KVAE, a family of tokenizers for latent diffusion models across audio, image and video. The set includes KVAE-Audio for full-band 48 kHz audio, KVAE-3D causal video tokenizers with 4x16x16 and 4x8x8 compression, and KVAE-2D for images with 8x compression and 32 channels. The authors report that KVAE matches or surpasses several open-source frontier tokenizers on reconstruction, generation and subjective evaluation metrics, and say they share training details, model-selection methods and ablations.
