Try giving it a river crossing puzzle with substitutions. QwQ can take a lot of time but it will solve it. Gemma will just confidently give you a wrong answer, and will keep giving you wrong answers if you point out the mistakes. Now, yes, QwQ will take a lot of tokens to get there (in one case it took it over 5 minutes running on Mac Studio M1 Ultra). Nevertheless, at least it can solve it.
