Vaswani, Shazeer, Parmar, Uszkoreit, Jones, Gomez, Kaiser, Polosukhin

The foundational paper that introduced the Transformer architecture, replacing recurrence with self-attention mechanisms. This architecture became the basis for GPT, BERT, and all modern LLMs.

Transformers Attention Architecture Foundational

Devlin, Chang, Lee, Toutanova (Google AI)

Introduced bidirectional pre-training for language understanding, revolutionizing NLP benchmarks. BERT's masked language modeling approach enabled transfer learning across diverse NLP tasks.

BERT Pre-training NLU Foundational

Lewis, Perez, Piktus, Petroni, Karpukhin, Goyal, et al. (Meta AI)

Introduced RAG, combining parametric and non-parametric memory for improved factual accuracy. This approach has become fundamental to modern AI assistants and search systems.

RAG Retrieval Knowledge Foundational

Brown, Mann, Ryder, Subbiah, et al. (OpenAI)

Demonstrated that scaling language models enables few-shot learning without fine-tuning. GPT-3's 175B parameters showed emergent abilities that surprised the AI community.

GPT-3 Scaling Few-shot Foundational

Wei, Wang, Schuurmans, Bosma, et al. (Google)

Demonstrated that prompting LLMs to show reasoning steps dramatically improves performance on complex tasks. Chain-of-thought has become a fundamental prompting technique.

Prompting Reasoning CoT

Bai, Kadavath, Kundu, Askell, et al. (Anthropic)

Introduced Constitutional AI (CAI), using AI feedback to train helpful and harmless assistants. This approach reduces reliance on human labeling for safety training.

Safety RLHF Alignment

Karpukhin, Oğuz, Min, Lewis, et al. (Meta AI)

Showed that dense vector representations outperform sparse methods like BM25 for passage retrieval. DPR became a foundational component of modern RAG systems.

Dense Retrieval DPR QA

Ouyang, Wu, Jiang, Almeida, et al. (OpenAI)

Introduced instruction tuning and RLHF for aligning LLMs with human intent. InstructGPT demonstrated that smaller aligned models can outperform larger unaligned ones.

RLHF Instruction Tuning Alignment

Khattab, Zaharia (Stanford)

Introduced late interaction for balancing efficiency and effectiveness in neural retrieval. ColBERT enables fine-grained matching while remaining practical for large-scale search.

ColBERT Neural IR Late Interaction

Touvron, Lavril, Izacard, et al. (Meta AI)

Released open-weight foundation models that match or exceed larger proprietary models. LLaMA democratized LLM research and spawned an ecosystem of open-source models.
