Foundation Model
A large AI model trained on broad data that can be adapted for many different tasks.
In Plain English
A Foundation Model is a large AI model trained on diverse data that serves as a starting point for many applications. Instead of building separate AI systems for each task, you can take one foundation model and adapt it for specific needs. OpenAI's GPT series, Anthropic's Claude, Google's Gemini, and Meta's open-source Llama are all foundation models that can be fine-tuned or prompted to do countless different things.
💡Real-World Example
The same foundation model that powers a general chatbot can be adapted to write marketing copy, analyze legal documents, or tutor students in math.
