The full NLP paradigm shift culminating in decoder-only dominance only became a practical deployment paradigm because the comprehensive efficiency stack (Flash Attention, speculative decoding, MoE, PagedAttention) addressed attention's quadratic scaling constraint — without efficiency breakthroughs, decoder-only dominance would be a theoretical victory unusable at frontier scale.
Justifications
SL — paradigm shift is only deployable because the efficiency stack made quadratic attention tractable
Antecedents (all must be IN):
- IN nlp-revolution-culminated-in-data-driven-decoder-dominance — The full NLP paradigm shift — from rules through neural methods to attention architectures — preceded and contextualizes the subsequent rise of decoder-only dominance, which coincided with evidence that data scaling matters more than parameter count. Autoregressive training's ability to exploit massive unsupervised corpora may have contributed to this architectural convergence, but the evidence does not establish the paradigm shift's endpoint as inseparable from the training data insight.
- IN decoder-only-scaling-requires-comprehensive-efficiency-stack — The decoder-only architecture won the scaling race through data volume advantage, but its quadratic attention cost means this dominance is only practically sustainable through the comprehensive efficiency stack (Flash Attention, PagedAttention, speculative decoding, MoE).
Dependents
These beliefs depend on this one:
- IN practical-agentic-ai-is-culmination-of-entire-nlp-evolution — The agentic AI paradigm — LLMs autonomously operating code, GUIs, and design tools — is the culmination of the entire NLP evolution: the decoder-only paradigm shift made practical by the efficiency stack created capable base models, while context window expansion (enabled by those same efficiency techniques) provided the substrate for multi-step autonomous operation.
