Llm

Introduction Large language models (LLMs) have moved from research labs into everyday products—chat assistants, code generators, and real‑time translators. While cloud‑based inference offers virtually unlimited compute, many use‑cases demand local execution: privacy‑sensitive data, intermittent connectivity, or ultra‑low latency for interactive devices. Running a multi‑billion‑parameter transformer on a modest edge platform is a classic “resource‑vs‑performance” problem. Two emerging technologies promise to shift that balance: Liquid Neural Networks (LNNs) – a class of continuous‑time recurrent networks that can adapt their computational budget on the fly, making them naturally suited for variable‑load inference. RISC‑V hardware acceleration – open‑source instruction‑set extensions (e.g., V‑extension, X‑extension for AI) and custom co‑processors that provide high‑throughput, low‑power matrix operations. This article walks through the theory, the hardware‑software co‑design, and a real‑world example of deploying a 7‑billion‑parameter LLM on a RISC‑V system‑on‑chip (SoC) with liquid layers. By the end you’ll understand: ...

Introduction The rise of large language models (LLMs) has transformed how we think about conversational agents. Early chatbots were essentially question‑answer machines—they took a user’s prompt, generated a textual response, and that was the end of the interaction. While useful, this model quickly hit a ceiling when real‑world problems demanded action: fetching data from APIs, orchestrating multi‑step processes, and making decisions based on evolving context. Enter agentic workflows—a paradigm where LLMs act as orchestrators that can invoke external tools, maintain state across turns, and reason about long‑term goals. The Open-Action Protocol (OAP) 2.0 is the latest open standard that formalizes this capability. It provides a language‑agnostic schema for describing actions, pre‑conditions, post‑conditions, and state transitions, enabling developers to build robust, composable agents without reinventing the wheel. ...

As model sizes climb into the hundreds of billions of parameters, inference performance becomes a decisive factor for cost, user experience, and environmental impact. Two techniques have risen to the forefront of performance engineering for LLM inference: ...

While LLMs excel at generating fluent text, they are not inherently grounded in your proprietary data. That gap is filled by Retrieval‑Augmented Generation (RAG)—a paradigm that couples a generative model with a fast, accurate retrieval component. When the retrieval component is a vector database, you gain the ability to perform semantic search over massive, unstructured corpora with sub‑second latency. ...

Introduction Large language models (LLMs) have transformed how we think about intelligent software. The early wave of applications focused on single‑agent interactions—chatbots, document summarizers, code assistants—where a user sends a prompt and receives a response. However, many real‑world problems demand coordinated, real‑time collaboration among multiple autonomous agents. Examples include: Dynamic customer‑support routing where a triage agent decides whether a billing, technical, or escalation bot should handle a request. Autonomous trading desks where risk‑assessment, market‑data, and execution agents must act within milliseconds. Complex workflow automation for supply‑chain management, where inventory, procurement, and logistics agents exchange information continuously. Building such systems goes far beyond prompting an LLM. It requires architectural patterns, stateful communication, low‑latency orchestration, and robust error handling. Fortunately, a vibrant ecosystem of open‑source orchestration frameworks—Ray, Temporal, Dapr, Celery, and others—provides the plumbing needed to turn a collection of LLM‑powered agents into a reliable, real‑time multi‑agent system (MAS). ...
