Local LLMs are open-source large language models (Llama 4, Qwen3.5, DeepSeek) that run on your own hardware instead of cloud APIs. Benefits: full privacy, offline capability, no usage limits, zero API costs.

How much VRAM do I need to run local LLMs?

7B parameter models need 8GB VRAM, 13B need 16GB, 70B need 48GB+ VRAM. GPU memory is more important than CPU memory. Use vLLM, Ollama, or LM Studio to optimize VRAM usage.

What is the difference between Ollama and LM Studio?

Ollama is a lightweight CLI tool for running models locally via simple commands. LM Studio provides a desktop GUI, better model management, and easier testing. Both support the same models (Llama, Mistral, etc.).

Can local LLMs match cloud models like GPT-4o?

Llama 4, DeepSeek V4, and Qwen3.5 perform similarly to GPT-4 on many tasks (coding, reasoning). GPT-5 and Claude 4.6 still excel on complex, multi-step reasoning. Test on your specific workload to compare.

How do I fine-tune a local model?

Fine-tuning local models requires: labeled training data (500+ examples), QLoRA framework for efficient training, 24GB+ VRAM (or use cloud GPU), and 1–4 hours of training time. LoRA adapters let you fine-tune without full retraining.
