LLM Stability Varies Wildly: Qwen 3.5 122B Outperforms GPT-5.5, Opus, Gemini

A recent discussion on LessWrong highlights the significant differences in the stability and reliability of various large language models when left to run unattended for extended periods. Models like Anthropic's Opus and Google's Gemini 3-Pro tend to destabilize or cause system issues within hours, while OpenAI's GPT-5.5 lasts longer, and Alibaba's Qwen 3.5 122B demonstrated remarkable stability over 50 agent-weeks. This disparity presents an opportunity for researchers to develop methods for improving AI truthfulness and minimizing unintended side effects, which could be integrated into future frontier models.
