Text-to-Image Synthesis: Transformer-Based Tokenization

AI-generated images are often conditioned on text prompts, which require precise mapping between linguistic structures and visual representations. Transformer-based architectures handle this by encoding text inputs into tokenized embeddings, which guide the image generation process.

The text-to-image workflow involves:

  • Tokenization – Text prompts are converted into numerical embeddings using tokenizers like Byte-Pair Encoding (BPE) or WordPiece segmentation.
  • Cross-Attention Layers – These layers align textual embeddings with visual feature maps, allowing AI to generate contextually relevant images.
  • Positional Encoding – Ensures that word order in the prompt influences visual composition, maintaining coherence in structured image synthesis.
