Model Specifications That Affect Hardware Requirements

Only the model properties that materially change memory, compute, or storage belong here.

Total Parameters

Sets the baseline weight footprint.

Active Parameters

Important for MoE compute demand and throughput.

Architecture

Dense and MoE models have different memory and compute behavior.

Context Window

Longer context increases KV-cache memory pressure.

Modalities

Vision or audio components can add memory and compute overhead.

Reference Precision

Quantized formats can lower practical local memory requirements.

How Quantization and Context Change Memory Requirements

Model memory is not one fixed number. Precision and context can move the same model into a different hardware class.

ShortLow

Basic chat and short prompts.

MediumModerate

Coding, documents, lightweight RAG.

LongHigh

Large document and repository context.

MaxVery high

Do not assume maximum advertised context is practical on minimum hardware.

Important: loading the model into memory is not the same as running it comfortably at maximum context.

What Increases Hardware Requirements?

Meeting the baseline does not guarantee the same experience under every workload.

Hardware factorLong Context

KV cache grows with context and can become the dominant runtime memory cost.

Memory ↑
Hardware factorConcurrent Users

Parallel requests increase memory pressure and reduce per-user throughput.

Compute ↑
Hardware factorRAG & Agents

Embedding, reranking, tools, and auxiliary models consume additional system resources.

System load ↑
Hardware factorMultimodal Inputs

Vision or audio components add encoder memory and processing overhead.

VRAM ↑
Hardware factorCPU Offload

Offload can make a model fit when VRAM is limited, but generation becomes slower.

Latency ↑
Hardware factorRuntime Choice

Ollama, llama.cpp, MLX, and vLLM target different hardware and memory strategies.

Efficiency varies

More Hardware Questions

This area is reserved for query fan-out questions that extend the page beyond the core hardware decision path.

Can this model run on 16GB RAM?

Demo placeholder: answer this with the verified quantization, runtime overhead, and realistic context assumptions.

What GPU is a practical match for this model?

Demo placeholder: map common VRAM tiers to full offload, partial offload, or unsuitable configurations.

Should I use Q4, Q5, or Q8 for this model?

Demo placeholder: answer based on the quality-memory tradeoff and the user's available RAM/VRAM.

Can multiple users share one local model server?

Demo placeholder: treat concurrency as a separate capacity-planning question rather than repeating the baseline requirement.
