Are Diffusion Language Models the Next Big Trend?
Introduction
While transformers dominate language AI, diffusion-based approaches are emerging as a potentially significant alternative architecture.
The Transformer Dominance
Current State
GPT, Claude, Gemini all use transformer architecture.
Strengths
- Proven at scale
- Well-understood training
- Strong performance
Limitations
- Autoregressive generation
- Sequential processing
- Scaling challenges
Diffusion for Language
The Concept
Applying diffusion principles to text generation.
How It Differs
- Non-autoregressive generation
- Iterative refinement
- Different training approach
Potential Advantages
