What is the best open source LLM?

Llama 3 405B is the most capable open-weight model. DeepSeek-R1 excels at reasoning. Qwen2 is best for multilingual. For running locally: Llama 3 8B (general), DeepSeek Coder (coding), Mistral (speed). Choice depends on your hardware and use case.

Can open source LLMs compete with GPT-4?

The gap has narrowed significantly. Llama 3 405B and DeepSeek-R1 approach GPT-4 on many benchmarks. For specific tasks (coding, math), fine-tuned open models can match or exceed GPT-4. The trade-off is hosting costs vs API costs.

How do I self-host an LLM?

Easiest: Ollama for local development. Production: vLLM for high-throughput serving. You need a GPU with sufficient VRAM (8GB minimum for small models, 80GB+ for large). Cloud GPUs (Lambda Labs, RunPod) are cost-effective for intermittent use.

What is quantization and should I use it?

Quantization reduces model precision (e.g., 16-bit to 4-bit) to decrease memory usage and increase speed. A 70B model at 4-bit fits in 40GB VRAM instead of 140GB. Quality loss is minimal for most tasks. Use GGUF format with Ollama or AWQ/GPTQ for vLLM.

What GPU do I need to run open source LLMs?

For 7B models: RTX 3060 (12GB) or better. For 13B: RTX 4070 (16GB). For 70B quantized: RTX 4090 (24GB) or A100 (40GB). Apple M2/M3 Macs with 32GB+ unified memory can run most models efficiently. Cloud GPUs are cost-effective for occasional use.

What is the difference between Llama, Mistral, and DeepSeek?

Llama (Meta) is the most popular, well-supported, and versatile. Mistral offers excellent speed-to-quality ratio in smaller sizes. DeepSeek excels at reasoning and coding tasks. All are Apache 2.0 or similar permissive licenses. Try each for your specific use case.

Can I use open source LLMs commercially?

Most open source LLMs allow commercial use. Llama 3 has a permissive license for companies under 700M users. Mistral and Qwen are Apache 2.0 (fully open). DeepSeek is MIT licensed. Always check the specific model license—some have restrictions on certain uses.
