Just out of curiosity, did you set the reasoning effort to high?

I've seen big jumps in performance between medium and high reasoning. Not that this is will solve your particular issue, but curious to see what settings you had.

Edit: I gave this a shot. My settings were temperature = 0.00 (not sure if these models respect temp settings but did it just in case), I also set reasoning effort to high. I'm using the groq-hosted version.

This was my prompt

"You have a fox, a chicken and some grain. The chicken will eat the grain if left alone with it. The fox is vegetarian, for religious reasons, and will also eat the grain if left alone with it. You need to get all across a river, but your boat can only take one at a time. How do you proceed?"

This was the response:

"*Solution – 7 moves*

| Move | What you take | What’s left on the left bank | What’s on the right bank |

|------|--------------|----------------------------|------------------------|

| 1 | *Take the grain* across | Fox, Chicken | *Farmer + Grain* |

| 2 | *Return alone* | *Farmer + Fox + Chicken* | Grain |

| 3 | *Take the fox* across | Chicken | *Farmer + Fox + Grain* |

| 4 | *Bring the grain back* | *Farmer + Grain + Chicken* | Fox |

| 5 | *Take the chicken* across | Grain | *Farmer + Chicken + Fox* |

| 6 | *Return alone* | *Farmer + Grain* | Chicken + Fox |

| 7 | *Take the grain* across | – | *Farmer + Fox + Chicken + Grain* |

*Explanation*

- The grain is the only thing that can be eaten, and it cannot be left alone with either the fox or the chicken. - So the grain must always be with the farmer whenever any other animal is on the same side.

The sequence above never leaves the grain with the fox or the chicken without the farmer, and after the seventh move all three items are safely on the far side."
