1. Pick an inference engine Start here

Your engine determines speed, hardware support and ease of use. The most popular options in 2026:

Ollama — easiest entry point; one-line model pulls and a built-in API. Great for beginners and Mac users.
llama.cpp — C/C++ core powering most local tooling. Runs GGUF models on CPU, CUDA, Metal, Vulkan and ROCm.
vLLM — high-throughput GPU serving with PagedAttention; ideal for multi-user or production workloads.
LM Studio — polished desktop GUI for browsing, downloading and chatting with GGUF models, no terminal needed.

$ ollama run qwen3.5:27b\n$ ./llama-server -m model.gguf -ngl 99 -c 8192

2. Understand quantization

Quantization shrinks weights from 16-bit down to fewer bits, trading a little quality for big memory savings.

Q8_0 — near-lossless, ~1 byte/param. Use when you have the VRAM.
Q4_K_M — sweet spot. ~4.5 bits/param with minimal quality loss; the default most people run.
Q3 / Q2 — emergency tier for fitting big models on small cards; noticeable degradation.
Prefer a larger model at Q4 over a smaller at Q8 when quality matters.

3. Memory math (VRAM estimate)

At Q4 you need roughly 0.55 GB per billion parameters, plus context overhead.

7B @ Q4 → ~5 GB · fits an 8 GB card.
14B @ Q4 → ~9 GB · fits 12 GB.
32B @ Q4 → ~20 GB · needs 24 GB (RTX 4090 / 3090).
70B @ Q4 → ~42 GB · dual-GPU or 48 GB+, or offload to RAM.

Long context inflates the KV cache; a 128K window can add several GB on top.

4. Hardware tips

Apple Silicon shines for local LLMs thanks to unified memory — M-series with 64GB+ runs large MoE models comfortably.
NVIDIA remains fastest via CUDA; the 3090/4090's 24GB is the consumer sweet spot.
CPU + RAM offload works for big models but is slow; expect single-digit tokens/sec.
MoE models activate only a fraction of params per token, so they run far faster than their total size suggests.

5. Performance tips

Set -ngl / GPU layers as high as your VRAM allows to offload the whole model to GPU.
Lower temperature (0.1–0.3) for code and factual tasks; raise it (0.7–1.0) for creative writing.
Enable flash attention and KV-cache quantization to fit longer contexts.
For reasoning models, allow plenty of output tokens so chain-of-thought isn't cut off.
