Conversations

Lifecycle of conversation threads, visitor identity, message streaming, and context windows.

Overview

A Conversation represents an active exchange between a visitor and the assistant. Conversations maintain chronological history, retrieved knowledge references, and telemetry events.

Conversation Lifecycle

Initiation: A conversation begins when a visitor opens the widget or the auto-greeting triggers.

Session Attachment: The conversation binds to the visitor's anonymous session ID or authenticated user token.

Message Exchange: Incoming queries generate assistant responses with streaming tokens.

Completion / Expiry: Inactive conversations automatically archive after 24 hours of inactivity.

Real-Time Streaming

Asiyst streams assistant responses using Server-Sent Events (SSE) over HTTP/2. This guarantees near-instant Time to First Token (TTFT < 350ms) and enables word-by-word avatar speech bubble updates.

Context Sliding Window

To optimize token efficiency while maintaining coherent dialogue, Asiyst uses a 10-turn sliding context window:

Recent messages remain fully detailed in memory.

Older turns are summarized into a compact session summary injected into the system prompt.
