Open Source AI
AI models whose code and weights are publicly available for anyone to use and modify.
In Plain English
Open Source AI refers to AI models where the underlying code, architecture, and sometimes the trained weights are freely available. This allows researchers, companies, and individuals to use, study, and build upon these models. Notable open-source models include Meta's Llama 4, Mistral, DeepSeek, and many models on Hugging Face. Open source AI promotes transparency, innovation, and allows organizations to run AI on their own servers.
💡Real-World Example
A startup can download Llama and run it on their own servers, customizing it for their specific needs without paying licensing fees.
