From c569638fac3c0ae8562b3e0fb20bf446a1b3e118 Mon Sep 17 00:00:00 2001 From: Matic Jurglic Date: Wed, 2 Sep 2026 14:03:32 +0200 Subject: [PATCH 1/2] Set Sonnet 5 reasoning effort to low Sonnet 5 thinks by default at the provider's highest effort. In the assistant that shows as minutes of reasoning before any content, or a generation that spends its whole output budget on reasoning. With an effort on the card the host stamps it on the room's active-llm event and the ai-bot forwards it.

Medium is the level that works for this workflow.
