Models · Illustrated guide

Language models

A language model produces text from patterns it learned during training and the information supplied with a request. It can explain, summarise and draft; it can also be wrong.

Small language models

A small language model has fewer internal parameters than a larger model. It can be useful for focused tasks with a smaller computing footprint, but it still needs testing on the actual work.

Agents · Illustrated guide

AI agents

An AI agent uses a model to choose steps and use permitted tools toward a goal. It can look up information and prepare work, with limits on what it may do and when a person must approve.

Agent orchestration

Agent orchestration coordinates several AI steps or agents: who handles each part, what information moves between them and how the results become one usable output.

Documents · Illustrated guide

Document intelligence

Document intelligence turns information in files into something a team or system can use. It can recognise text, understand layout, extract named fields and flag values that need checking.

Optical character recognition

Optical character recognition, or OCR, turns text in an image or scanned page into machine-readable characters. It gives software something to search and process, but the characters it produces can still be wrong.

Knowledge · Illustrated guide

Grounded answers

A grounded answer is based on relevant source information supplied to the model. In a company assistant, that often means finding permitted documents first, then answering with references the reader can check.

Knowledge graphs

A knowledge graph represents things and the relationships between them. Instead of keeping a supplier, contract and department as isolated records, it can show how they connect.

Multimodal AI

Multimodal AI works with more than one kind of information, such as text and images. The supported combinations depend on the model; the term does not mean every model can handle every file type.

Private AI

Private AI is an arrangement in which access to AI systems and the data they use is controlled for an organisation. Where the application, files and model run—and what leaves that boundary—determines what “private” means in practice.
