RTX 40 Series Makes LLM Blazing Fast! The Complete Guide to Inference Optimization for Individual Developers [2026 Latest Edi...

Hello everyone! I'm soy-tuber, an AI researcher and individual developer. I usually push my RTX 5090 to its limits, running LLMs with vLLM, and diligently working on agent development with Claude Code as my partner. In recent years, the evolution of LLMs has been remarkable, and individual developers can now reap their benefits. However, running high-performance LLMs still requires significant GPU resources. Especially for individual developers with mid-range GPUs like the RTX 40 series, concerns such as "insufficient VRAM" and "slow inference speed" are never-ending.
