qwen3-coder:30b vs qwen3:14b

Both models answered the same one-shot tasks under identical rules — no retries, answers published unedited. Two separate axes, never blended: does the code actually run, and how do blind-scored text answers hold up against a written gold answer.

Model	Runnable sims	Blind text avg	Failure modes
qwen3-coder:30b	25% (21/85)	9.34 (38 scored)	ERR 36 · STAT 9 · BLANK 18 · HANG 1
qwen3:14b	28% (24/85)	8.71 (38 scored)	ERR 39 · STAT 10 · BLANK 12
