Test-Time Scaling Makes Overtraining Compute-Optimal

Nicholas Roberts, Sungjun Cho, Zhiqi Gao +7

Modern LLMs scale at test-time, e.g. via repeated sampling, where inference cost grows with model size and the number of samples. This creates a trade-off that pretraining scaling…

Pareto Optimal Code Generation

Gabriel Orlanski, Nicholas Roberts, Aws Albarghouthi +1

Generate-then-rank is the dominant test-time scaling (TTS) paradigm for code generation, but scaling accuracy by sampling and executing more candidates makes comprehensive verifica…

Tabby: A Language Model Architecture for Tabular and Structured Data Synthesis

Sonia Cromp, Satya Sai Srinath Namburi GNVV, Mohammed Alkhudhayri +4

While advances in large language models (LLMs) have greatly improved the quality of synthetic text data in recent years, synthesizing tabular data has received relatively less atte…

Pretrained Hybrids with MAD Skills

Nicholas Roberts, Samuel Guo, Zhiqi Gao +5

While Transformers underpin modern large language models (LMs), there is a growing list of alternative architectures with new capabilities, promises, and tradeoffs. This makes choo…

R&B: Domain Regrouping and Data Mixture Balancing for Efficient Foundation Model Training

Albert Ge, Tzu-Heng Huang, John Cooper +7

Data mixing strategies have successfully reduced the costs involved in training language models. While promising, such methods suffer from two flaws. First, they rely on predetermi…

MoRe Fine-Tuning with 10x Fewer Parameters

Wenxuan Tan, Nicholas Roberts, Tzu-Heng Huang +5

Parameter-efficient fine-tuning (PEFT) techniques have unlocked the potential to cheaply and easily specialize large pretrained models. However, the most prominent approaches, like…
