Qwen3.6-27B: Community seeks best post-training method

A Reddit user is seeking community insights on the most effective post-training methods for the Qwen3.6-27B model. They are particularly interested in comparing supervised fine-tuning (SFT) with LoRA, continued pre-training, and reinforcement learning (RL) to understand which approach best adds capabilities without degrading existing performance. The user highlights recent research suggesting RL may mitigate catastrophic forgetting better than SFT, but also notes that RL can cause forgetting. They are looking for direct comparisons and benchmark results on Qwen3.6-27B, specifically regarding regressions in unrelated areas like coding, reasoning, and tool use. AI

IMPACT Understanding optimal fine-tuning strategies is crucial for efficiently adapting large language models to specific tasks without performance degradation.

RANK_REASON User is asking for community experiences and insights on model training methods, referencing research papers but not announcing new findings or releases.

    Has anyone compared pre-training, SFT/LoRA and reinforcement post-training on Qwen3.6-27B?
