Assumptions
- GPU VRAM assumption: 12GB from NVIDIA RTX 3060 12GB.
- System RAM: 32GB.
- Ratings assume Q4-style quantization, moderate context, one local model running at a time. Treat them as fit guidance, not a speed estimate.

Local AI performance is approximate. Results depend on quantization, context length, backend, drivers, RAM, and whether the model fits fully in VRAM.
Order and handover
Key practical details
After payment or quote request
You receive a confirmation email. We check availability and confirm any practical substitutions before continuing.
Assembly and QA
Planned work includes software, drivers, a GPU/AI smoke test, thermal load sanity check, and memory/storage health checks.
Handover in Estonia
Pickup or local delivery method and timing are agreed after availability is checked.
Warranty and support
Warranty depends on the component, manufacturer, and retailer. Questions continue through the order or quote email thread.
Changes and cancellations
Changes are confirmed in writing; after sourcing or assembly begins, custom-order handling may depend on order state.
Payment security
Card details are entered in Stripe checkout. LLMLab.ee does not collect or store full card numbers.
AI terms in plain language
VRAM
Memory on the graphics card; usually the main limit for local AI model size.
Unified memory
Apple Silicon memory shared by CPU and GPU. Useful for local AI, but not identical to NVIDIA VRAM.
7B / 13B / 70B
A rough model-size signal. Larger numbers usually need more memory and may run slower.
q4 / quantization
A compressed 4-bit model that uses less memory, sometimes with quality or speed tradeoffs.
