11 LLM evaluation tools compared for 2026: what each one measures, where it fits in the lifecycle, and how to pick one for your architecture and privacy needs.
A practical guide to LLM evaluation: which metrics matter, how the methods compare, how to build an eval set, and how to gate releases on evals inside CI.
TL;DR: LLM evaluation metrics are measurements used to assess the performance of large language models. They cover areas such as output quality, factual grounding, safety, and oper...
In this article, you will learn how to evaluate LLM applications using the three dominant open-source frameworks — RAGAS, DeepEval, and Promptfoo — and why...
Monika Sharma of Salesforce on DeepEval as pytest for LLMs, the RAG and safety metric taxonomy, choosing thresholds, and where eval tests fit in the pyramid.
An eval is a systematic measurement of an AI system’s behavior. Not a test that passes or fails, a measurement that returns a number with…Continue reading on Data Science Collectiv...
LLM-as-a-judge scores individual outputs well but can't evaluate a full AI agent conversation. Learn the techniques, code, and biases that make judges reliable.
What a production incident taught me about trusting a model to judge another model's work The post The LLM Judge That Kept Agreeing With Itself appeared first on Towards Data Scien...
Rhea Goel of Amazon on replacing a re-ranker with an LLM: natural language objectives, fine-tuning, DPO, hard and soft constraints, distillation and LLM judges.
Building Production-Grade LLM Evaluation Pipelines: From Vibes to Metrics How we replaced "looks good to me" with automated evaluation catching 92% of hallucinations before deplo...
Moving beyond naive accuracy with agreement statistics, calibration analysis, error profiling, and evaluator observability.Continue reading on Medium »
LLM benchmarks score general model capability, evals score your application. See what each can gate, where benchmarks break, and how to build an eval suite.
LLM testing explained: types, key evaluation metrics, how to build a testing strategy, popular frameworks, common challenges, and real-world use cases.

The Thomson LLM, which will be integrated into CoCounsel Legal’s Tabular Analysis feature next month, was tested against models from Anthropic, OpenAI and Google.
Large Language Models (LLMs) are increasingly used not only to generate content, but also to evaluate the output produced by other models. This technique is commonly known as LLM-a...
Demystifying its use cases in complete detail, with a discussion of its competitors & a detailed comparison among all of them! As a bonus…Continue reading on Medium »
LLMs can produce a convincing media recommendation in a few seconds. The more useful question is whether the recommendation is correct: are the reach calculations right, are the as...
Originally appeared on OmbuLabs.ai.Tracing helps answer an important question: what happened? But knowing what happened isn’t the same as knowing whether it was any good. That’s wh...
A pull request arrives. A few hundred lines of Java implementing the new discount rule: tiered thresholds, a regional exception, something about loyalty tiers that nobody can quite...
How LLM hallucination detection works: groundedness scoring, semantic entropy, judge models and fine-tuned detectors compared, with where each one fails.
A small language model runs on ordinary hardware fast enough to serve one user, and an LLM is one that does not. SLM vs LLM compared, with 200 measured runs.
Про LLM-wiki здесь уже было несколько хороших статей (1, 2 и 3), поэтому подробно останавливаться на идее Andrej Karpathy не буду. В двух словах: вместо RAG-ретривера - wiki-агент,...
