What's the best free ChatGPT alternative?

For quality: Llama 3.1 70B via Jan matches 90-95% of GPT-4. For accessibility: Llama 3.1 8B runs on budget GPUs and still delivers good results.

Can I run ChatGPT alternatives offline?

Yes! All local alternatives (Llama, DeepSeek, Qwen, etc.) run completely offline after the initial download. No internet required.

What GPU do I need for ChatGPT alternatives?

Entry level: RTX 3060 12GB ($300) runs 7B-8B models. Mid-range: RTX 4070 Ti Super 16GB ($800) runs 32B models. High-end: RTX 4090 24GB ($1,600) runs 70B models.

Are local models as good as ChatGPT?

For most tasks, yes. Llama 3.1 70B and DeepSeek V3 approach GPT-4 quality. Smaller models (7B-8B) are noticeably weaker but still useful.
