The early wave—prompt‑to‑completion APIs—proved that a single model could answer questions, generate code, or draft marketing copy with surprising competence. Yet, as enterprises moved from prototypes to production, a new set of challenges emerged: ...

For high‑traffic applications, the naïve approach of sending every user request directly to the model quickly becomes unsustainable. Traditional caching—keyed by raw request strings—offers limited relief because even slight phrasing changes invalidate the cache entry. ...

By coupling a large language model (LLM) with a non‑parametric memory store—typically a vector index of document embeddings—RAG systems can answer factual queries, cite sources, and stay up‑to‑date without costly model retraining. ...

Introduction Large language models (LLMs) have transformed how we build conversational assistants, code generators, and, increasingly, autonomous agents that can plan, act, and learn without human supervision. The most visible limitation of current LLM‑driven agents is the context window: a fixed‑size token buffer (e.g., 8 k, 32 k, or 128 k tokens) that the model can attend to at inference time. When an agent operates over days, weeks, or months, the amount of relevant information quickly exceeds this window. ...

Introduction The convergence of large language models (LLMs) with edge‑centric hardware is reshaping how developers think about on‑device intelligence. A new wave of neural‑integrated RISC‑V laptops—devices that embed AI accelerators directly into the RISC‑V CPU fabric—promises to bring powerful conversational agents, code assistants, and content generators to the desktop without relying on cloud APIs. Yet, running a modern LLM locally on a laptop with limited DRAM, modest power envelopes, and a heterogeneous compute stack is far from trivial. Optimizing these models requires a blend of model‑centric techniques (quantization, pruning, knowledge distillation) and hardware‑centric tricks (vector extensions, custom ISA extensions, memory‑aware scheduling). ...
