What are AI tools in the context of LLMs?

• A. External hardware accelerators used to speed up training.
• B. Data cleaning utilities used before training.
• C. Functions provided to an LLM to extend its capabilities, such as web search or API access.
• D. Graphical interfaces for editing prompts.

Answer: (C)

AI tools are functions provided to an LLM to extend its capabilities, allowing the model to act beyond its internal knowledge. They let the model call external services or run tasks that require up-to-date information or real-world actions, such as performing a web search, querying an API, or executing code. This makes the model capable of retrieving fresh data, accessing specific tools, or interfacing with other systems to complete a task. Tools are not about speeding up training or inference (that would be hardware accelerators), nor about preprocessing data before training (data cleaning utilities), nor about the user interface for editing prompts. They're the set of capabilities the model can invoke during use to interact with the outside world.
