Gemini 3 Pro: the frontier of vision AI

I tried this with Claude:

``` > [Image #1] Create a unicode "ascii-art" version of this image, with the optimal path through the maze highlighted in a solid colour.

I'll create an ASCII art version of this maze with the solution path highlighted!

  The path from the mouse () to the cheese () is marked with ● characters. This shows the optimal route through the maze, navigating through the corridors while avoiding all the walls!

```

Suffice to say, it didn't do either part right.

Honestly, even though it failed, I'm kind of impressed that the trajectory mostly stays in the lines. If you remove all but two openings, does it work? The drawing you show has more than two openings, some of which are inaccessible from the inside of the maze.

It's ASCII art, so the "trajectory" will always stay within the lines, because you can't have the ● and ║ characters intersect each other.

The only impressive part would be that the trajectory is "continuous", meaning for every ● there is always another ● character in one of the 4 adjacent positions.

I know the characters can’t cross. By intersect, I mean two dots on either side of a boundary line in the direction of the path.

I dunno why people are surprised by this. This is what you get with text->text. Reasoning doesn't work text->text.
