From 6403ff4ec4f5b5f09db8ff485cb7b6befa7e6535 Mon Sep 17 00:00:00 2001 From: leaph Date: Fri, 26 Dec 2025 15:41:48 +0100 Subject: [PATCH] feat(iflow): add model-specific thinking configs for GLM-4.7 and MiniMax-M2.1 - GLM-4.7: Uses extra_body={"thinking": {"type": "enabled"}, "clear_thinking": false} - MiniMax-M2.1: Uses reasoning_split=true for OpenAI-style reasoning separation - Added preserveReasoningContentInMessages() to support re-injection of reasoning content in assistant message history for multi-turn conversations -
