AI Model Detector & Auto Downloader

Deep hardware scanning · Live model registry · Smart recommendations · Auto install

A precise, transparent tool that scans your entire system — from OS and CPU instruction sets to GPU drivers and available VRAM — then queries the live Ollama library, Hugging Face, and community issue trackers to recommend and install the best local AI model for your hardware.

Unlike tools that rely solely on GPU data or maintain a hardcoded model list, this tool fetches its registry fresh every run, so newly released models appear automatically without requiring a software update.

Install

pip3 install ai-model-detector --break-system-packages

Requirements: Python ≥ 3.11, internet connection (for live registry fetch)

Quick Start

# Scan hardware, fetch live registry, recommend + optionally install
ai-model-detector

# Filter by use-case
ai-model-detector --category code
ai-model-detector --category vision
ai-model-detector --category math
ai-model-detector --category reasoning

# Show more recommendations
ai-model-detector --top 10

# Import a macOS system profile instead of live scan
ai-model-detector --import ~/Desktop/MyMac.spx

# Pull a specific model directly
ai-model-detector --pull llama3.2:3b

# Output full JSON (pipe to other tools)
ai-model-detector --json > results.json

# List already-installed models
ai-model-detector --installed

How It Works

1 — System Scan

Reads hardware directly from the OS — no config file needed:

On macOS, machdep.cpu.features and machdep.cpu.leaf7_features are both queried so AVX2 is correctly detected on Intel Macs (it only appears in leaf7_features).

On macOS, pass --import file.spx to read a system_profiler export instead of scanning live hardware.

2 — Live Registry Fetch

Every run fetches fresh data — no model list is stored in the source code:

• Ollama library — all available models with tags, sizes, and pull counts
• Hugging Face API — top GGUF models by download count (shown for reference; flagged as manual-download only)
• Ollama GitHub issues — open bug reports mapped to model names

3 — Compatibility Evaluation

Each model is assessed with factual classifications — there is no universal 0–100 suitability score:

UNKNOWN is never treated as FITS. If no verified model fits available memory, automatic installation is disabled and you must explicitly override.

4 — Install

Runs ollama pull <model> with live streaming output. Only models from the Ollama library are offered for auto-install — HuggingFace-only GGUF models are shown in the list but flagged as manual-download. If Ollama isn't installed, platform-specific install instructions are provided.

CLI Reference

usage: ai-model-detector [options]

options:
  --import FILE        Import a macOS .spx system profile
  --category CAT       Filter: chat | code | vision | math | reasoning | embedding
  --top N              Number of recommendations to show (default: 5)
  --json               Output full results as JSON
  --installed          List already-installed Ollama models
  --pull MODEL         Pull a specific model (e.g. llama3.2:3b)
  --no-hf              Skip Hugging Face supplemental data
  --verbose / -v       Enable debug logging
  --version            Show version and exit

macOS .spx Import

Export your system profile from the macOS System Information app:

1. Open System Information (Cmd+Space → "System Information")
2. File → Save… → choose System Information (.spx)
3. Run: ai-model-detector --import ~/Desktop/MyMac.spx

Why Not Just Use GPU Data?

Tools that only look at GPU VRAM miss critical constraints:

• A model might fit in VRAM but not in RAM when layers spill to CPU
• CPU instruction sets (AVX2 vs AVX-512) drastically affect CPU-offload speed
• Free disk space at download time is often the real bottleneck
• Community bug reports reveal models that perform poorly on specific hardware regardless of specs

This tool checks all of these, not just VRAM.
