Transformer dominance stems from a unique combination of architectural flexibility and hardware synergy — the unified attention mechanism enabled rapid speciation into encoder-only (BERT) and decoder-only (GPT) variants within one year of the original paper, while GPU-friendly parallelism eliminated the compute bottleneck that constrained all RNN-based predecessors.

Justifications

SL — Architectural flexibility × hardware fit produced faster paradigm branching than any prior architecture family

Antecedents (all must be IN):

  • IN transformer-architecture-unified-yet-specialized — The Transformer is simultaneously a unified architecture (all variants built on multi-head self-attention) and a specialized one (encoder-only, decoder-only, encoder-decoder serve distinct task families).
  • IN bert-gpt-divergence-from-common-ancestor — BERT and GPT represent a speciation event from a common ancestor: both derived from the 2017 Transformer in the same year (2018), but chose opposite pretraining strategies (masked vs. causal LM) and opposite architectural halves (encoder vs. decoder), yielding fundamentally different capability profiles.
  • IN transformer-gpu-synergy-explains-dominance — Transformer dominance is partly explained by hardware synergy: eliminating sequential recurrence enables massive parallelism, which GPUs — the dominant ML training hardware — are specifically designed to exploit.
