How Do You Turn a Local LLM Into an API Server? Run it through Ollama or Jan, both of which expose an OpenAI-compatible endpoint on your own machine: http://localhost:11434/v1 for Ollama, http://localhost:1337/v1 for Jan. Point any tool built for the OpenAI SDK at that URL with any placeholder API key, and it behaves exactly like … Read more

How Much VRAM Does Kimi K3 Need? The short answer, now that the weights are public: the download alone is 1.56 TB, and that is the part that locks you out. The context window, counterintuitively, is nearly free. Moonshot’s launch post confirms a 2.8-trillion-parameter Mixture-of-Experts model shipping natively in MXFP4, and the published files measure … Read more

Which llama.cpp performance flags matter, and in what order? Set them in this order: size the model first, then GPU layers, then MoE offload, then context, then the KV cache type, then speculative decoding, then multi-GPU split. Each step changes what the next one can do, which is why a flat list of twenty flags … Read more

Can You Really Run a 405B Model on 8 GB VRAM? Loading it: yes, demonstrably: AirLLM’s layer-streaming technique is real engineering. Running it at a published speed: nobody has shown that number. As of July 2026, no measured throughput figure, tokens per second, for Llama 3.1 405B via AirLLM exists in public: not in the … Read more

AMD Ryzen AI Halo vs NVIDIA DGX Spark: The 128GB AI Desktop Showdown Which is better for local AI: the AMD Ryzen AI Halo or NVIDIA DGX Spark? The NVIDIA DGX Spark is better for pure AI inference workloads, delivering 2.7× to 13.4× higher token throughput than the AMD Ryzen AI Halo thanks to hardware … Read more

What is the best GPU for running local LLMs in 2026? The best GPU for local LLM inference in 2026 depends entirely on your VRAM budget, not your compute budget. A used NVIDIA RTX 3090 at $650 to $850 provides 24GB of VRAM, enough to run the full 31B to 32B model tier at Q8_0 … Read more

Can a gaming PC run local AI models? Yes. Any gaming PC with a dedicated GPU and at least 8GB of VRAM can run local large language models offline in 2026. An 8GB GPU like the RTX 4060 runs Llama 3.1 8B under Q4_K_M quantization. A 16GB GPU like the RTX 4060 Ti 16GB runs … Read more

What VRAM do you need to run local LLMs in 2026? Running local LLMs in 2026 requires a minimum of 8GB VRAM for 4B to 8B parameter models under Q4_K_M quantization. 16GB VRAM handles models up to 14B parameters comfortably, with Gemma 4 12B fitting natively including its multi-modal stack. Dense 30B+ models require 24GB … Read more
