Ollama vs LM Studio vs Hugging Face Free Inference — I Benchmarked All Three, One Is 4x Faster

#opensource #ai #llm #python

Everyone says "just run local models, it's free." Nobody tells you how free — or that the performance gap between free options is massive. I ran the same model (Qwen2.5-Coder-7B, Q4_K_M) through the three most popular free options on the same machine. One was 4x faster. One was borderline unusable.

The Setup

  • Machine: RTX 4060 Ti 16GB, Ryzen 7 7700, 32GB RAM
  • Model: Qwen2.5-Coder-7B-Instruct Q4_K_M (4.7 GB)
  • Task: generate a 500-token code completion, measured over 10 runs, median reported
  • Cost of everything below: $0

Results

Tool Tokens/sec First-token latency VRAM used Setup time
Ollama 68 t/s 0.4s 5.8 GB 2 min
LM Studio 61 t/s 0.5s 6.1 GB 5 min (GUI)
HF Inference API (free) ~15 t/s effective 2-8s (queue) 0 (cloud) 1 min

Ollama wins on speed. But that's not the whole story.

Ollama — The Daily Driver 

curl -fsSL https://ollama.com/install.sh | sh
ollama pull qwen2.5-coder:7b
ollama run qwen2.5-coder:7b
Enter fullscreen mode Exit fullscreen mode

Two minutes, done. The OpenAI-compatible API means every tool that works with GPT works with this:

from openai import OpenAI

client = OpenAI(base_url='http://localhost:11434/v1', api_key='ollama')
resp = client.chat.completions.create(
    model='qwen2.5-coder:7b',
    messages=[{'role': 'user', 'content': 'Write a Python LRU cache'}]
)
print(resp.choices[0].message.content)
Enter fullscreen mode Exit fullscreen mode

Hugging Face Free Inference — The Trap

The HF free Inference API sounds great (no GPU needed!) until you use it. Shared queue, rate limits, models unloaded between calls. My "500 token generation" took 20-40 seconds wall time. Fine for testing a model before downloading. Useless for anything interactive.

The genuinely underrated HF free resource: Spaces with ZeroGPU. Community spaces get free A10G time. I ran Flux image generation and Whisper transcription through Gradio Spaces for weeks, $0, no queue most of the time.

Google Colab Free — The Sleeper Pick

People dunk on Colab's free tier ("only T4, sessions die"), but a free T4 GPU for 12 hours is absurd value if you work around the limits:

# Runs on Colab free tier — persistent-ish Ollama via tunnel
!curl -fsSL https://ollama.com/install.sh | sh
!nohup ollama serve &
!ollama pull qwen2.5-coder:7b
# Serve via cloudflared tunnel, call from your local editor
Enter fullscreen mode Exit fullscreen mode

Yes, it disconnects. But for fine-tuning experiments (Unsloth + QLoRA on a T4), free Colab beats paying $0.50/hr for a rented GPU when you're iterating.

My Actual Verdict

  • Daily coding assistant: Ollama, no contest (68 t/s, instant, offline)
  • Trying a new model before committing 8GB of disk: HF Inference API
  • Fine-tuning / batch jobs / no GPU: Colab free T4 + Unsloth
  • LM Studio: only if you want a GUI to browse models — same llama.cpp under the hood, slightly slower defaults

The controversial take: paying $20/month for ChatGPT Plus to write code while a free 7B model running locally handles 80% of daily coding questions is a tax on people who haven't spent 2 minutes installing Ollama. The remaining 20% (hard refactors, subtle bugs) — sure, use the frontier model. But 80% at $0 vs 100% at $20 is math people refuse to do.

What's your local model setup — and be honest, what did you try that was too slow to be usable?
