Why It Matters
Most legal AI products are built on a handful of LLMs from OpenAI, Anthropic, Google, Meta and others, with legal data, workflows and safeguards added on top. Knowing which model a vendor uses, and whether you can choose, helps you compare tools and understand where your data is processed.

- Generative AI
- AI that produces new text, images or code from a prompt. In legal work it drafts, summarizes, translates and answers questions over documents.
- Foundation model
- A large, general-purpose AI model trained on broad data that other products are built on top of. Most LLMs are foundation models.
- Context window
- The amount of text an AI model can consider at once, measured in tokens. Larger windows let a model read longer documents in one pass.
- Fine-tuning
- Further training an existing AI model on a narrower set of examples, such as legal documents, so it performs better on that kind of work.
