1. Transformer Architecture Evolution
Recent benchmark tests show GPT-4 Turbo achieves 23% better summary coherence scores than its predecessor GPT-3.5 through improved attention mechanisms. Comparative studies reveal:
GPT-3.5 (2022)
Coherence: 76%
Brevity: 82%
Params: 175B
GPT-4 Turbo (2024)
Coherence: 93%
Brevity: 88%
Params: ~1T*
*Estimated via model scaling laws
2. Domain-Specialized Model Landscape
The current market offers several specialized summarization models:
- LegalBERT-Sum (2023): Achieves 98% accuracy on contract clause extraction in independent evaluations
- MedSum-XL (2024): FDA-cleared for diagnostic support with 89% physician approval rate
- NewsSum (2023): Reuters-tested factual accuracy of 92% for news summarization
3. Emerging Multimodal Approaches
