Generating High‑Resolution Images with Only 64 Tokens: How MacTok Overcomes Posterior Collapse

MacTok introduces semantic masking and dual‑space alignment to prevent posterior collapse in continuous image tokenizers, enabling high‑quality generation with just 64‑128 tokens and achieving strong gFID scores on ImageNet at 256×256 and 512×512 resolutions.

Introducing FAR: A Frequency‑Progressive Autoregressive Paradigm for Image Generation

The paper presents FAR, a frequency‑aware autoregressive framework that predicts image tokens from low‑frequency to high‑frequency components using a continuous tokenizer, and demonstrates its efficiency and quality on ImageNet and text‑to‑image benchmarks compared with existing AR and VAR methods.
