From b142fbba7dc093cf78724978e8767c53f93b4a13 Mon Sep 17 00:00:00 2001 From: Abk <192931312+abk234@users.noreply.github.com> Date: Tue, 20 Jan 2026 06:57:15 -0500 Subject: [PATCH] Enhance error handling in LiteLLM integration, including specific guidance for OpenRouter and Ollama model errors. Increase memory consolidation timeout from 60 to 180 seconds for better handling of complex tasks.
