Dimension Reducers builds tools to formalize, stress-test, verify, and structure mathematical knowledge. They offer solutions for LLM training, automated refereeing, and retrieval that understands mathematical structure. Their platform includes tools for refereeing at scale, adversarial testing ("torture testing"), and structured Retrieval Augmented Generation (RAG).
Key products include DiRe-JAX (a dimensionality reduction library), arXiv Math Semantic Search, arXiv Proof Audit Database, Mathematics Torture Chamber, and a Lean 4 Formalization Pipeline. They also publish research and benchmarks in mathematical formalization and OCR, emphasizing semantic accuracy and robustness.
1. **Retrieval-Augmented Generation (RAG):** Ground responses in trusted, retrieved data instead of relying on the model's memory.
2. **Require Citations:** Demand sources for factual claims; retract claims without support.
3. **Tool Calling:** Use LLMs to route requests to verified systems of record (databases, APIs) rather than generating facts directly.
4. **Post-Generation Verification:** Employ a "judge" model to evaluate and score responses for factual accuracy, regenerating or refusing low-scoring outputs. Chain-of-Verification (CoVe) is highlighted.
5. **Bias Toward Quoting:** Prioritize direct quotes over paraphrasing to reduce factual drift.
6. **Calibrate Uncertainty:** Design for safe failure by incorporating confidence scoring, thresholds, and fallback responses.
7. **Continuous Evaluation & Monitoring:** Track hallucination rates and other key metrics to identify and address performance degradation. User feedback loops are critical.
This article details building end-to-end observability for LLM applications using FastAPI and OpenTelemetry. It emphasizes a code-first approach, manually designing traces, spans, and semantic attributes to capture the full lifecycle of LLM-powered requests. The guide advocates for a structured approach to tracing RAG workflows, focusing on clear span boundaries, safe metadata capture (hashing prompts/responses), token usage tracking, and integration with observability backends like Jaeger, Grafana Tempo, or specialized LLM platforms. It highlights the importance of understanding LLM behavior beyond traditional infrastructure metrics.
RAG combines language models with external knowledge. This article explores context & retrieval in RAG, covering search methods (keywords, TF-IDF, embeddings/FAISS/Chroma), context length challenges (compression, re-ranking), and contextual retrieval (query & conversation history).
This article discusses how to effectively utilize Large Language Models (LLMs) by acknowledging their superior processing capabilities and adapting prompting techniques. It emphasizes the importance of brevity, directness, and providing relevant context (through RAG and MCP servers) to maximize LLM performance. The article also highlights the need to treat LLM responses as drafts and use Socratic prompting for refinement, while acknowledging their potential for "hallucinations." It suggests formatting output expectations (JSON, Markdown) and utilizing role-playing to guide the LLM towards desired results. Ultimately, the author argues that LLMs, while not inherently "smarter" in a human sense, possess vast knowledge and can be incredibly powerful tools when approached strategically.
Adafruit highlights the development of “pycoClaw,” a fully-featured AI agent implemented in MicroPython and running on a $5 ESP32-S3. This agent boasts capabilities like recursive tool calling, persistent memory using SD card storage, and a touchscreen UI, all built with an async architecture and optimized for performance through C user modules. The project is open-source and supports various hardware platforms, with ongoing development for RP2350, and is showcased alongside other Adafruit news including new product releases, community events, and resources for makers.
This guide walks you through building production-grade MCP servers that expose your organization's internal data to AI models, covering authentication, multi-tenancy, streaming, and deployment patterns.
Learn how to build a simple semantic search engine using sentence embeddings and nearest neighbors, focusing on the limitations of keyword-based search and leveraging large language models for semantic understanding.
This article discusses how AI tools can be used to enhance the reading experience by providing instant access to information and background details, similar to using a dictionary or Wikipedia, but with the ability to ask more complex questions. The author shares personal examples of using AI while reading 'The Dark Forest' and other books to clarify plot points and gain a better understanding of the material.
This article explains the differences between Model Context Protocol (MCP), Retrieval-Augmented Generation (RAG), and AI Agents, highlighting that they solve different problems at different layers of the AI stack. It also covers how ChatGPT routes prompts and handles modes, agent skills, architectural concepts for developers, and service deployment strategies.
