Visualizing RAG Retrieval in Real-Time
Read Full Article: Visualizing RAG Retrieval in Real-Time
VeritasGraph introduces an innovative tool that enhances the debugging process of Retrieval-Augmented Generation (RAG) by providing a real-time visualization of the retrieval step. This tool features an interactive Knowledge Graph Explorer, built using PyVis and Gradio, which allows users to see the entities and relationships the Language Model (LLM) considers when generating responses. When a user poses a question, the system retrieves relevant context and displays a dynamic subgraph with red nodes indicating query-related entities and node size representing connection importance. This visualization aids in understanding and refining the retrieval logic, making it an invaluable resource for developers working with RAG systems. Understanding the retrieval process is crucial for improving the accuracy and effectiveness of AI-generated responses.

Building LLMs: Evaluation & Deployment
Read Full Article: Building LLMs: Evaluation & Deployment![Part 4 (Finale): Building LLMs from Scratch – Evaluation & Deployment [Follow-up to Parts 1, thru 3]](https://www.tweakedgeek.com/wp-content/uploads/2026/01/featured-article-8167-300x171.png)
The final installment in the series on building language models from scratch focuses on the crucial phase of evaluation, testing, and deployment. It emphasizes the importance of validating trained models through a practical evaluation framework that includes both quick and comprehensive checks beyond just perplexity. Key tests include historical accuracy, linguistic checks, temporal consistency, and performance sanity checks. Deployment strategies involve using CI-like smoke checks on CPUs to ensure models are reliable and reproducible. This phase is essential because training a model is only half the battle; without thorough evaluation and a repeatable publishing workflow, models risk being unreliable and unusable.

Expanding Attention Mechanism for Faster LLM Training
Read Full Article: Expanding Attention Mechanism for Faster LLM Training
Expanding the attention mechanism in language models, rather than compressing it, has been found to significantly accelerate learning speed. By modifying the standard attention computation to include a learned projection matrix U, where the rank of U is greater than the dimensionality d_k, the model can achieve faster convergence despite more compute per step. This approach was discovered accidentally through hyperparameter drift, resulting in a smaller model that quickly acquired coherent English grammar. The key insight is that while attention routing benefits from expanded "scratch space," value aggregation should remain at full dimensionality. This finding challenges the common focus on compression in existing literature and suggests new possibilities for enhancing model efficiency and performance. Summary: Expanding attention mechanisms in language models can dramatically improve learning speed, challenging the traditional focus on compression for efficiency.

Tool Tackles LLM Hallucinations with Evidence Check
Read Full Article: Tool Tackles LLM Hallucinations with Evidence Check
A new tool has been developed to address the issue of hallucinations in large language models (LLMs) by breaking down their responses into atomic claims and retrieving evidence from a limited corpus. This tool compares the model's confidence with the actual support for its claims, flagging cases where there is high confidence but low evidence as epistemic risks rather than making "truth" judgments. The tool operates locally without the need for cloud services, accounts, or API keys, and is designed to be transparent about its limitations. An example of its application is the "Python 3.12 removed the GIL" case, where the tool identifies a high semantic similarity but low logical support, highlighting the potential for epistemic risk. This matters because it provides a method for critically evaluating the reliability of LLM outputs, helping to identify and mitigate the risks of misinformation.
