ShellWhisperer-1.5B — Ultra-Fast Shell Command Assistant

1,100+ downloads · 986MB · 20+ tok/s · Runs on anything

What Is This?

ShellWhisperer is the fastest shell command assistant on the planet. At just 986MB (Q4_K_M), it runs on everything from a Raspberry Pi to a gaming PC. Fine-tuned from Qwen2.5-0.5B on 100K+ shell command traces, it predicts bash, zsh, PowerShell, and DevOps commands with uncanny accuracy.

Unlike general models that kind of know shell commands, ShellWhisperer was trained exclusively on shell tasks — it doesn't write poetry, it gets you the right command fast.

Quick Start

Ollama (recommended)

ollama run FableForge-AI/shellwhisperer

llama.cpp

./llama-cli -m shellwhisperer-1.5b-Q4_K_M.gguf --prompt "find all files larger than 100MB" -n 512

Python

from transformers import AutoModelForCausalLM, AutoTokenizer
model = AutoModelForCausalLM.from_pretrained("fableforge-ai/ShellWhisperer-1.5B")
