Messages

Messages are Anvia's provider-neutral transcript format. Completions, agents, memory, tools, and UI adapters share the same role and content contracts.

The message shape

import { Message } from '@anvia/core'

const messages = [
  Message.system('Answer clearly and concisely.'),
  Message.user('Summarize this incident.'),
]

Use the factory helpers to create valid content arrays and metadata. Provider adapters translate these normalized messages into their native API formats.

Check the selected completion model before sending images, documents, tools, reasoning, or other optional content.
