At the heart of RAG lies vector similarity search—the process of transforming unstructured text, images, or audio into high‑dimensional embeddings and then finding the most similar items in a massive collection. ...

Introduction Large language models (LLMs) such as GPT‑4, LLaMA, and PaLM have demonstrated remarkable capabilities across a wide range of natural‑language tasks. Their raw performance, however, is often a starting point rather than a finished product. Real‑world applications typically require fine‑tuning—adapting a pre‑trained model to a specific domain, style, or task. Traditional fine‑tuning updates every parameter in the model, which can be prohibitively expensive in terms of compute, memory, and storage, especially when dealing with models that contain billions of weights. ...

Table of Contents Introduction From Rule‑Based Chatbots to Agentic Systems What Are Liquid Neural Networks? 3.1 Core Concepts: Continuous‑Time Dynamics 3.2 Liquid Time‑Constant (LTC) Cells Why Liquid Networks Enable Agentic Workflows Open‑Source Implementations Worth Knowing Designing an Agentic Workflow with Liquid NNs 6.1 Defining the Agentic Loop 6.2 State Representation & Memory 6.3 Action Generation & Execution Practical Example 1: Real‑Time Anomaly Detection in IoT Streams Practical Example 2: Adaptive Customer‑Support Assistant Deployment Considerations 9.1 Hardware Acceleration 9.2 Model Versioning & Monitoring Performance Benchmarking & Metrics Challenges, Pitfalls, and Future Directions Conclusion Resources Introduction The last decade has witnessed a dramatic shift in how we think about conversational AI. Early rule‑based chatbots gave way to large language models (LLMs) that can generate human‑like text, and today we stand on the cusp of the next evolution: agentic workflows—systems that not only converse but act autonomously in dynamic environments. ...

SorryDB: Can AI Really Prove Real-World Math Theorems? Imagine you’re a mathematician knee-deep in a complex proof, but you hit a wall. Instead of giving up, you jot down a placeholder—“sorry, I’ll finish this later”—and move on. Now, picture AI stepping in to fill those gaps automatically. That’s the promise of SorryDB, a groundbreaking benchmark introduced in the paper “SorryDB: Can AI Provers Complete Real-World Lean Theorems?” (arXiv:2603.02668). This isn’t some abstract academic exercise; it’s a practical testbed pulling “sorry” statements from 78 real GitHub projects, challenging AI to prove theorems that actual mathematicians are working on. ...
