Autoregressive Image Generation
Autoregressive image models generate a sequence of visual tokens one at a time, conditioning each next token on earlier tokens and any text prompt.

Pfupiso
This sequential procedure differs from masked parallel decoding.
Kudzika Kwakadzika
PixelRNN/PixelCNN model conditional distributions over pixels in an ordered raster sequence. The original DALL·E work instead uses a discrete VAE to represent images as tokens and trains an autoregressive Transformer on text and image tokens; its paper reports a 250-million image-text-pair dataset. Such models sample tokens sequentially. MaskGIT uses a different masked-token iterative decoding approach to predict multiple tokens in parallel.
Kuitwa muNyika yeChokwadi
PixelCNN and PixelRNN model image pixels autoregressively in their published image-generation studies.
The original DALL·E paper tokenizes images with a discrete variational autoencoder before sequence modeling.
A causal attention mask prevents a Transformer decoder from using future image tokens during autoregressive prediction.
MaskGIT is a separate masked-token method that iteratively predicts many image tokens in parallel.
Ramangwana reAutoregressive Image Generation
Compare autoregressive and parallel masked-image methods using matched image quality, compute and sampling conditions. Evaluate prompt alignment and artifacts on the intended domain. The cited papers establish their own architectures and experiments, not a universal winner or future deployment trend.
