We present BytePredictor, a novel architecture for universal sequence modeling that operates at the byte level across multiple modalities. By treating all data types as raw byte sequences, our model can learn and generate diverse content types including text, images, audio, and their combinations. The architecture incorporates state-of-the-art advances such as Multi-Query Attention (MQA) and Rotary Position Embeddings (RoPE), while introducing novel optimizations for byte-level prediction tasks.

• Byte-Level Processing: Operates on raw bytes (0-255) enabling universal data handling
• Enhanced Multi-Query Attention: Modified MQA mechanism with fewer key/value heads
• Rotary Position Embeddings: Position-aware representations without sequence length limitation
• QK-Normalization: Improved attention mechanism stability
• Modality-Agnostic Training: Unified approach to multi-modal learning

Our model introduces several key innovations:

1. Universal Tokenization: Direct byte-level processing eliminating the need for modality-specific tokenizers
2. Automatic Modality Detection: Novel algorithms for identifying data types in generated sequences
3. Boundary-Aware Generation: Specialized attention mechanisms for handling modal transitions

• Reduced memory footprint through MQA
• Efficient rotary embeddings implementation
• Optimized QK normalization for byte-level attention

Preliminary evaluation shows promising results across modalities:

• Text Generation: Comparable to specialized models
• Image Synthesis: Effective for various formats
• Multi-Modal Generation: Novel capabilities in cross-modal transitions
