Local models, real GPUs.

How We Measure Things

Rigorous, reproducible benchmarking — one variable at a time.

Same Prompt, Same Rig

Every test uses the identical prompt on the same hardware rig. No moving targets — only one variable changes per run.

One Variable, One Test

We isolate each factor — batch size, context length, quantization level — and change exactly one thing at a time so results are comparable.

Model Reloaded Every Run

The model is freshly reloaded into VRAM before every benchmark, eliminating cache effects and ensuring clean, consistent measurements.

Fully Published

Every prompt and every result file is published. You can verify the methodology, reproduce it yourself, or fork the work.

The Rig

One machine, one GPU — real local inference.

VRAM

NVIDIA RTX 3090

24 GB VRAM — dedicated to local model inference

  • NVIDIA GeForce RTX 3090
  • 24 GB GDDR6X VRAM
  • Dedicated local inference rig — no cloud, no APIs

Model Server

LM Studio runs locally on the same machine, serving models through an OpenAI-compatible API for consistent benchmarking.

LM Studio

PC Magik Lab

Computer Service & Homelab Operator from Poland

A YouTube series dedicated to running open-source large language models on real local hardware — no cloud APIs, no managed services.

The goal is straightforward: measure how these models behave under controlled conditions on a single consumer GPU, publish every prompt and result file openly, and let the community verify everything for themselves.
