Self-Hosted LLMs in Production: Real-World Limits and Practical Lessons

KDnuggets has published a comprehensive analysis of real-world constraints and lessons learned from deploying self-hosted LLMs at scale. The article moves beyond theoretical performance metrics to address practical problems: memory management under load, latency variability, prompt engineering for local models, and the hidden costs of infrastructure maintenance.

Understanding these production realities is essential for teams making the local-versus-cloud decision. Local inference offers privacy and cost benefits, but introduces operational complexity around resource allocation, monitoring, and degradation handling that cloud providers abstract away. The article's focus on "workarounds" acknowledges that local LLM systems require different operational mindsets than cloud APIs.

Reading the KDnuggets analysis is essential preparation for teams planning production local deployments, as it surfaces the practical constraints that benchmarks and proof-of-concepts often hide.
