Learn Open-Source AI Models

DeepSeek, Qwen, Llama, Mistral and Kimi — running capable AI on your own terms, the licence terms that matter, and when open beats closed.

Choose between open-weight models on evidence rather than benchmarks
Run models locally and understand the hardware constraints honestly
Read model licences before building a product on one
Know when a closed frontier API is genuinely the better answer
