Self-Hosting Your First LLM

Large language model API bills are driving teams to consider self-hosting their own AI systems, which has become practical with modern tools and quantized models that can run on single machines. Using models like Qwen3.5-27B with Q4_K_M quantization on GPUs like the L40S or A100, teams can deploy production-grade LLMs for agent workflows at costs comparable to API services while gaining privacy, customization options, and eliminating rate limits.
