Open Source AI
AI models and tools released with open licenses that allow anyone to use, modify, and distribute them. Open-source AI democratizes access and enables community-driven improvement.
Why It Matters
Open-source AI has become a powerful force, with models like Llama and Mistral rivaling proprietary models. It shapes the competitive landscape and accessibility of AI.
Example
Meta's Llama 3 being released with open weights, allowing researchers and companies to download, fine-tune, and deploy it freely for their own applications.
Think of it like...
Like open-source software (Linux, Firefox) — anyone can use, modify, and improve it, creating a virtuous cycle of innovation that benefits everyone.

Foundation Model
A large AI model trained on broad data at scale that can be adapted to a wide range of downstream tasks. Foundation models serve as the base upon which specialized applications are built.
Llama
A family of open-weight large language models released by Meta. Llama models are available for download and customization, making them the most widely adopted open-source LLM family.
Mistral

Hugging Face
The leading open-source platform for sharing and discovering AI models, datasets, and applications. Hugging Face hosts the Transformers library and a community hub with thousands of pre-trained models.
Model Weights
The collection of all learned parameter values in a neural network. Model weights are what you download when you get a pre-trained model — they encode everything the model learned.
