From 0b1c2ee5b51a148a62bd6fb02aaf9e381808be51 Mon Sep 17 00:00:00 2001 From: William Gill Date: Sun, 19 Apr 2026 14:18:49 -0500 Subject: [PATCH] Image Studio: tighten system prompt, add /no_think for Qwen 3.x MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit User reported the model writing a multi-paragraph 'editing plan' instead of calling edit_image, only firing the tool when explicitly told to. Two underlying causes: 1. The previous system prompt was conversational ('ALWAYS / NEVER' lists with discussion) — Qwen-style models read that as topics to think about rather than rules to obey. Replaced with terse, imperative dispatcher framing: 'You do not respond in prose. Every user message MUST result in exactly one tool call.' 2. Qwen 3.x ships with thinking mode on by default. Reasoning models almost universally degrade native function calling — they plan how to use a tool instead of just calling it. Prepended /no_think (Qwen 3.x recognises this token and skips reasoning). No-op for non-Qwen-3 base models. Removed the long after-action paragraph that encouraged elaborate follow-ups; replaced with 'at most one short sentence'.
