Typing indicators

​

Defaults

• Direct chats: typing starts immediately once the model loop begins.
• Group chats with a mention: typing starts immediately.
• Group chats without a mention: typing starts only when message text begins streaming.
• Heartbeat runs: typing is disabled.

​

Modes

• never — no typing indicator, ever.
• instant — start typing as soon as the model loop begins, even if the run later returns only the silent reply token.
• thinking — start typing on the first reasoning delta (requires reasoningLevel: "stream" for the run).
• message — start typing on the first non-silent text delta (ignores the NO_REPLY silent token).

​

Configuration

{
  agent: {
    typingMode: "thinking",
    typingIntervalSeconds: 6,
  },
}

{
  session: {
    typingMode: "message",
    typingIntervalSeconds: 4,
  },
}

​

Notes

• message mode won’t show typing for silent-only replies (e.g. the NO_REPLY token used to suppress output).
• thinking only fires if the run streams reasoning (reasoningLevel: "stream"). If the model doesn’t emit reasoning deltas, typing won’t start.
• Heartbeats never show typing, regardless of mode.
• typingIntervalSeconds controls the refresh cadence, not the start time. The default is 6 seconds.
