This tutorial walks you through the open‑source “AI Agents From Scratch” project, teaching how to build a fully local AI agent without any pre‑made framework by covering core modules, 14 step‑by‑step examples, advanced reasoning architectures, and minimal system requirements.
A comprehensive evaluation shows that while diffusion language models achieve higher generation speed through parallel decoding, they suffer from severe causal reasoning and formatting deficiencies, lagging far behind autoregressive models on embodied and tool‑calling agent tasks.
This article surveys the design of autonomous large‑language‑model agents, detailing their modular architecture—including profiling, memory, planning, and execution—while also reviewing common profiling methods, memory structures, planning techniques, action strategies, and various learning approaches such as exemplar, human‑in‑the‑loop, and environment‑feedback training.
