Terms that come up often with Qevron and AI APIs.

AI Gateway A middle layer that unifies many AI providers behind one API. Qevron is an AI gateway.

API Key A secret string (sk-...) that proves a request is made on your behalf. See Authentication.

Base URL The API's base address. For Qevron it's https://app.qevron.ai/v1.

Embedding An array of numbers (a vector) representing the meaning of text. The foundation of search and RAG. See Embeddings.

Group The access and quota unit for keys. Determines which models can be accessed and the limits.

Channel The upstream source serving a model: provider + address + credential. See Providers.

LLM (Large Language Model) An AI model that generates text (e.g. chat models).

MCP (Model Context Protocol) A protocol that lets models access external tools in a standard way. See MCP / SSE.

Moderation Classifying whether text contains harmful/inappropriate content. See Moderations.

Prompt The input text / instruction you give the model.

Quota The total usage/balance a group can spend.

RAG (Retrieval-Augmented Generation) A method to get more accurate answers by retrieving your own documents for the model. See RAG guide.

Rerank Sorting a list of documents by relevance to a query. See Rerank.

SSE (Server-Sent Events) A continuous, one-way data stream from server to client. Streaming is built on this.

STT (Speech-to-Text) Converting speech to text (transcription). See Audio.

Token A chunk of text the model processes (roughly a syllable/word). Usage and pricing are token-based.
