Find the best local AI model for your GPU — terminal UI

fitmyllm

Run the right LLM locally. Automatically.

Install

pip install fitmyllm

Or run without installing:

pipx run fitmyllm

Setup

Get your free API key at fitmyllm.com/?tab=mcp, then:

fitmyllm setup
# Paste your API key (starts with fml_)

Or set it as an environment variable:

export FITMYLLM_API_KEY=fml_your_key_here

Run

fitmyllm

Features

Screen	Description
Quick Run	Zero-config: detect GPU → recommend best model → download GGUF → start server → chat. No decisions needed
Find Models	Auto-detect GPU, 11 filters (use case, context, size, family, quant, speed...), 30+ models ranked by score
Find GPU	GPU recommendations for any model with budget, speed, vendor, and quant filters
Enterprise	10-tab deployment analysis: overview, risk, checklist, TCO, scaling, SLA, GPU matrix, performance, fine-tuning, architecture
Model Library	Browse all installed models from every backend (Ollama, llama-server, local GGUF). Chat, delete, disk usage
Compare	Side-by-side comparison of up to 4 models with all metrics
Install	Choose quantization, pick engine (8 supported), or download GGUF directly from HuggingFace with progress bar
Chat	Talk to models via any backend with real-time streaming and collapsible thinking blocks
Run Benchmark	Select from installed/recommended models, backend-agnostic speed test with delta vs predicted speed
Tier List	Models and GPUs ranked S-F with cloud GPU alternatives
Benchmarks	Leaderboard sortable by 8 benchmark metrics
GPU Prices	Search and compare GPU pricing with vendor filter
Command Simulator	Interactive parameter tuning for 8 engines
Charts	ASCII score/speed/VRAM bars and quality-vs-speed scatter plot

Multi-Backend Support

The CLI auto-detects running inference backends and works with any of them:

Backend	Port	Notes
Ollama	11434	Full support: pull, run, chat, model listing
llama-server	8080	llama.cpp HTTP server — auto-started or manual
OpenAI-compatible	8080	vLLM, LM Studio, or any /v1/chat/completions server

Quick Run can auto-start llama-server with optimal parameters (GPU layers, context length, batch size) calculated from your hardware.

GGUF Model Management

Download and manage GGUF models without Ollama:

• Download from any HuggingFace repo by quantization level
• Inventory tracked in ~/.fitmyllm/models/inventory.json
• Storage in ~/.fitmyllm/models/ (configurable)
• No extra dependencies — uses httpx for downloads
