Test Shows Qwen 3.6 27B Lacks Agentic Reliability Compared to 122B
TokenRingAI · reddit · 2026-07-07
Deep testing of Qwen 3.6 27B (8bit/16bit) via llama.cpp on an RTX 6000 revealed noticeable errors every 4 rounds on average during multi-turn agentic tasks, failing to follow instructions stably. While the 27B outperforms the 3.5 series in single-shot prompts and long-form generation, its reliability in multi-turn agentic workflows is severely lacking, leading the author to revert to Qwen 3.5 122B. This contrasts with positive feedback from other users and has sparked attention.
