SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Local LLM runtimes like Ollama, llama.cpp, LM Studio, and vLLM are frequently misconfigured — models overflow VRAM into slow CPU offload, quantization levels degrade output quality, context lengths exhaust memory, and routing logic leaks sensitive data to cloud endpoints. This Skill produces a concrete configuration review with calculated VRAM requirements, throughput baselines, and privacy boundary verification instead of generic optimization advice. ## Core Features & Use Cases - Hardware and Model Fit Analysis: Calculates VRAM requirements using weights plus KV cache formulas, identifies CPU offload penalties, and validates quantization levels against task types. - Privacy and Routing Audit: Verifies that local-only data never reaches cloud endpoints including fallback conditions, checks telemetry settings, API binding, and outbound network traffic during inference. - Throughput Benchmarking: Measures time-to-first-token, tokens per second, and peak VRAM against reference benchmarks to detect configuration problems. - Use Case: Before deploying Ollama to process medical records on a machine with a 24 GB GPU, run this review to confirm the quantized model fits in VRAM, the router enforces privacy classification before capability routing, and no telemetry sends prompt content externally. ## Quick Start Review my local Ollama setup running Llama 3 8B on a 16 GB VRAM GPU and check the configuration, privacy boundaries, and throughput before I use it with sensitive data.

Frequently Asked Questions about local-llm-runtime-review

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I check if my LLM model fits in GPU VRAM?▼

Calculate model VRAM as parameter count times bits per weight divided by 8, plus KV cache size based on layers, heads, context length, and batch size. For example, Llama 3 8B at Q4_K_M needs roughly 5 GB total at 4K context, fitting an 8 GB GPU.

What quantization level should I use for local LLM inference?▼

Q4_K_M is the default for most production use cases with minimal quality loss. Use Q5_K_M or Q6_K when output quality matters more than memory, and avoid Q2_K or Q3_K for reasoning-heavy or user-facing tasks since quantization loss outweighs parameter count benefits.

Why is my local LLM inference so slow?▼

Slow generation usually comes from VRAM overflow causing CPU offload, which can reduce speed by 5-20x due to PCIe bandwidth limits. Check that -ngl matches layers that fully fit in VRAM, verify context length is not set to maximum, and measure a throughput baseline against reference benchmarks.

How do I prevent sensitive data from reaching cloud LLM endpoints?▼

Make privacy classification the first routing gate before any capability or complexity check, and verify fallback conditions never route local-only data to cloud. Confirm with network monitoring that no outbound connections occur during inference and the API binds to localhost only.

Does Ollama send telemetry or prompt data externally?▼

Runtimes like LM Studio may include prompt metadata in default telemetry settings. Audit every telemetry field before processing sensitive workloads, disable anything not confirmed as non-content, and monitor traffic with tcpdump during generation to confirm no exfiltration.

When should I not use a local LLM runtime review?▼

Skip this review if your application uses only cloud-hosted LLM APIs, if the question concerns prompt quality or fine-tuning rather than inference configuration, or if infrastructure is a cloud GPU cluster managed by a platform team.
