Verifiers can enhance language model (LM) performance by scoring and ranking a set of generated responses, but high-quality verifiers today are either unscalable (like human judges) or of limited practical use (such as formal proof tools like Lean). While LM-based judges and reward models serve as general-purpose verifiers, they still fall short of the performance levels achieved by oracle verifiers,…

Modern semi-supervised learning (SSL) methods rely on pseudolabeling and consistency regularization. Pseudolabeling is typically performed by comparing the model’s confidence scores and a predefined threshold. While several heuristics have been proposed to improve threshold selection, the underlying issues of overconfidence and miscalibration in confidence scores remain largely unaddressed, leading to inaccurate pseudolabels, degraded test accuracy, and prolonged training. We take…

Rubrics aren’t just for evaluation—they’re a blueprint for better data annotation. In this post, we explore how structured rubrics enable scalable, high-quality labeling and evaluation of GenAI systems. Learn how Snorkel and leading labs use rubrics to align human and automated judgment and accelerate trusted AI development.

In this post, we unpack how Snorkel built a realistic benchmark dataset to evaluate AI agents in commercial insurance underwriting. From expert-driven data design to multi-tool reasoning tasks, see how our approach surfaces actionable failure modes that generic benchmarks miss—revealing what it really takes to deploy AI in enterprise workflows.

In this post, we will show you a specialized benchmark dataset we developed with our expert network of Chartered Property and Casualty Underwriters (CPCUs). The benchmark uncovers several model-specific and actionable error modes, including basic tool use errors and a surprising number of insidious hallucinations from one provider. This is part of an ongoing series of benchmarks we are releasing across verticals…

LLM observability is crucial for monitoring, debugging, and improving large language models. Learn key practices, tools, and strategies of LLM observability.

Concept-based approaches, which aim to identify human-understandable concepts within a model’s internal representations, are promising for interpreting embeddings from deep neural network models, such as CLIP. While these approaches help explain model behavior, current methods lack statistical rigor, making it challenging to validate identified concepts and compare different techniques. To address this challenge, we introduce a hypothesis testing framework that…
