How to Cut LLM Inference Costs with KV Caching
Argues that treating the KV cache as a persistent, shared data asset — injected from fast storage via RDMA rather than recomputed — can reduce prefill costs by up to 20x and dramatically improve token throughput in enterprise LLM deployments.

- AI infrastructure
The systems, abstractions, and operational layers that make AI models usable at scale, from compute and caching to routing, governance, agent hosting, and credential management.
- Context engineering
Context engineering is the practice of deliberately constructing what an LLM receives in its context window — structuring, compressing, persisting, and retrieving information so agents produce reliable output across tasks and sessions.
- LLM engineering
LLM engineering spans the full stack of building with large language models: training, inference optimization, agent architecture, harness design, and the operational tradeoffs that determine whether model capability translates into reliable software.
- LLM inference
LLM inference covers how language models generate tokens from a prompt — spanning hardware constraints, serving architecture, caching strategies, quantization, routing, and cost — and has become its own engineering discipline as scale and cost pressures intensify.
- Production systems
The engineering decisions that determine how software behaves under real load, covering durability, observability, testing discipline, performance constraints, and the operational costs of failure.
