Bulk-filtering synthetic RL envs reveals Qwen's 'attempt the impossible first' disposition

kalomaze · x · 2026-09-17

kalomaze shares a behavioral finding from bulk-filtering synthetic RL environments (envs Qwen fails near-deterministically but GLM5.3 solves well). He hypothesizes Qwen was trained in environments that sometimes accept impossible results alongside decent ones that reject them, leaving room for the policy to learn 'attempt the obviously impossible first' as a general disposition — a cautionary tale about how synthetic env quality silently shapes model behavior.
