AI and LLM fundamentals

Document AI combines text extraction, OCR, layout/table understanding, and field extraction. A PDF may already contain usable text or require image interpretation. OCR reads characters; document understanding connects them to fields and structure.

Multimodal models process more than one kind of input or output, such as text with images or audio. Vision means interpreting visual content; audio understanding includes spoken words and sometimes sounds or vocal context. Support differs by model and…

Vision models interpret image content, such as objects, layout, handwriting, and visual relationships. Image understanding produces descriptions or structured observations; it does not automatically verify authenticity or determine business liability. Quality…

Speech-to-text converts spoken words into text. Text-to-speech produces spoken output from text. Audio understanding can also process nontext information in audio, depending on the model, but reliable interpretation of emotions or identity should not be…

A voice agent handles a live conversation, including listening, responding, interruption, and tools. Video understanding combines information from sampled frames, timestamps, and sometimes audio. Both involve timing and event coordination beyond an ordinary…

Priority key

Cost formula: input tokens × input rate + output tokens × output rate + tools/retrieval/embedding/infrastructure/review, with applicable caching and provider accounting. Prices must be checked for the real provider/model/account.

LiteLLM provides model-access abstraction and proxy/gateway capabilities. Portkey provides an AI gateway and operational controls. Cloud gateways can apply access and model traffic policies within an existing cloud API-management environment; exact AI…
