ModelScout (modelscout-llm)
Find local AI models that fit your hardware, with accurate memory and generation speed estimates.
Downloading a 10GB–50GB model file only to discover that it overflows your VRAM or crawls at 1 token per second is a frustrating experience. ModelScout inspects your machine and tells you exactly what open-source models will run smoothly — before you spend hours downloading weights.
Whether you're running on Apple Silicon (M1–M4), NVIDIA RTX, AMD Radeon / ROCm, Intel Arc, or CPU-only, ModelScout calculates real-world weights, KV cache requirements, and memory-bandwidth token generation speeds.
⚡ Quick Start with uv (Zero Installation)
You don't even need to clone a repository or set up a virtual environment. If you have uv installed, you can run ModelScout instantly via uvx:
# Scan your hardware and get the best matching models
uvx modelscout-llm@latest
# Launch the interactive local Web Dashboard (http://localhost:1234)
uvx modelscout-llm@latest web
# Inspect your detected GPU/CPU specs and AI capability score
uvx modelscout-llm@latest hardware
📦 Install via pip
You can also install ModelScout globally or into any Python 3.11+ environment:
pip install modelscout-llm
Once installed, the modelscout command is available everywhere:
# Run the scanner
modelscout
# Launch the Web UI
modelscout web
# Target a specific workload
modelscout --profile coding
modelscout --profile reasoning
modelscout --profile vision
# Plan hardware requirements for a model
modelscout plan "llama 3 70b"
# Generate ready-to-run Python code snippet
modelscout snippet "llama 3" --runner ollama
# Start an interactive chat session
modelscout run "llama-3.2-1b"
🛠️ Key Capabilities
- Native Hardware Probing: Automatically detects Apple Silicon unified memory & bandwidth, NVIDIA NVML/CUDA, AMD ROCm, Intel Arc, and CPU AVX/NEON instruction sets.
- Architecture-Aware Memory Engine: Accurately models weights + GQA/MQA KV cache footprints + activation buffers + framework overhead.
- Bandwidth-Bound Speed Estimates: Derives honest tokens/second ranges based on your system's actual memory bus bandwidth (GB/s).
- Interactive Web Interface: Complete browser dashboard running locally on port
1234, featuring hardware autocompletion, real-time filtering, and side-by-side model comparison. - Hardware Simulation: Test potential upgrades before buying hardware (e.g.
modelscout --gpu "2x RTX 4090"ormodelscout upgrade). - Flexible Formats: Export clean GitHub-flavored Markdown (
-m) or strict JSON (--json) for scripting and automation.
