Scaling Laws for Neural Language Models
OpenAI published foundational research establishing empirical scaling laws for neural language models, showing that model performance scales predictably with compute, data, and parameters. The work demonstrated power-law relationships between these factors and loss, providing a principled framework for allocating training resources. This paper became a cornerstone of modern large language model development strategy.

Scaling Laws for Reward Model Overoptimization
OpenAI published research investigating how reward model overoptimization scales with policy and reward model size in RLHF pipelines. The work characterizes the relationship between KL divergence from the initial policy and gold-standard reward, finding predictable degradation patterns as optimization pressure increases. This provides empirical grounding for understanding Goodhart's Law dynamics in language model fine-tuning and has implications for designing safer, more robust RLHF training regimes.
Best practices for deploying language models
Cohere, OpenAI, and AI21 Labs jointly published a preliminary set of best practices for organizations developing or deploying large language models. The document represents an early cross-industry effort to establish shared norms around responsible LLM deployment. This is a 2022 publication surfaced in a tier-1 feed.
How AI Training Scales: Gradient Noise Scale Predicts Batch Parallelizability
OpenAI researchers report that the gradient noise scale — a statistical metric measuring gradient variance relative to mean — reliably predicts the optimal batch size and degree of parallelizability across a wide range of neural network training tasks. The finding suggests that more complex tasks with noisier gradients can benefit from increasingly large batch sizes, removing a potential ceiling on scaling. The work frames training dynamics as a systematic, measurable process rather than empirical art.
Rosetta Neurons follow sublinear power-law scaling with model size, becoming more monosemantic at scale
A new arXiv paper investigates how neuron populations evolve with scale in both language models (up to 30B parameters) and vision models (up to 5B parameters), focusing on 'Rosetta Neurons' — neurons with similar activation patterns across independently trained models. The authors find Rosetta Neurons grow in absolute count but shrink as a fraction of total neurons, and exhibit a 'Neuron Polarization Effect' where they become increasingly monosemantic while non-Rosetta neurons remain less selective. An analytical model explains the sublinear power-law scaling, and the paper demonstrates practical utility via a targeted data-filtering case study for continued pretraining. The results extend scaling laws to neuron-level interpretability structure, linking model size to systematic changes in universality and specialization.
Evolution through large models
OpenAI published a blog post titled 'Evolution through large models' in June 2022, exploring the relationship between large-scale models and evolutionary or emergent capabilities. The post appears to examine how scaling laws and large model training relate to the emergence of novel behaviors and capabilities. As a Tier 1 source publication from OpenAI, it likely addresses foundational themes around capability emergence in large language models.
Language models are few-shot learners
OpenAI published the GPT-3 paper introducing a 175-billion-parameter autoregressive language model demonstrating strong few-shot learning capabilities across a wide range of NLP tasks. The work showed that scaling language models dramatically improves task-agnostic, few-shot performance, often matching or exceeding fine-tuned models without any gradient updates. This paper became a foundational milestone in the development of large language models and the modern AI landscape.
Shannon Scaling Law: A Noisy-Channel Framework for LLM Capacity and Non-Monotonic Training Phenomena
Researchers propose the Shannon Scaling Law, a theoretical framework that models LLM training as information transmission over a noisy channel using the Shannon-Hartley theorem. By mapping model parameters to channel bandwidth and training tokens to signal power, the framework introduces a fundamental SNR-based capacity limit that explains non-monotonic phenomena like catastrophic overtraining and quantization-induced degradation that classical power-law scaling laws cannot capture. Validated on Pythia and OLMo2 under Gaussian noise, quantization, and fine-tuning perturbations, the law achieves strong R² scores and successfully extrapolates from 6.9B to 12B parameter models trained on up to 307B tokens. The framework outperforms both classical and perturbation-aware scaling laws, predicting U-shaped performance degradation when SNR is insufficient.
Why Language Models Hallucinate
OpenAI published research explaining the mechanisms behind language model hallucination. The work connects improved evaluation methods to enhanced AI reliability, honesty, and safety. The body is sparse on technical detail, but the framing positions this as foundational research relevant to alignment and deployment trust.
