AI agents are LLM-powered systems that plan, act, and iterate autonomously; active research and engineering practice reveal deep tensions between coordination complexity, reliability, tool design, and the human oversight they still require.

AI safety covers the technical and behavioral risks of deployed AI systems, from sycophantic belief distortion to misaligned model behavior, and the tooling built to detect and constrain those failures at inference time.

Benchmarks in multi-agent AI research measure coordination overhead, error propagation, and task performance, exposing how architectural choices translate into real costs across single- and multi-agent systems.

The practical discipline of building, evaluating, and operating systems that use large language models, spanning knowledge architecture, agent control flow, inference optimization, and the human and organizational costs of getting it wrong.

LLM inference spans the full stack from VRAM constraints and quantization choices on consumer hardware to latency optimization in production agent services, with tooling debates about transparency, local runtimes, and cost-efficient alternatives to large models.
