Researchers have demonstrated that emergent capabilities in transformer language models arise randomly during training, not smoothly. These capabilities, such as pattern completion and indirect object identification, appear abruptly when the model learns specific, sparse attention patterns. The difficulty of learning these patterns is influenced by context length and sparsity, with more attention heads improving efficiency and head dimension offering diminishing returns. Alternative architectures like MLP-Mixer can outperform transformers on tasks requiring complex attention patterns. AI
