Claude vs GPT vs Gemini

Each of the three models plays four main characters — one in each group (politics, business, society, development), drawn by lot before the start. The numbers come only from what happened in the city, with no AI judging.

To be fair: a character's role shapes behaviour too. The mayor has more levers than the activist, and the banker more money than the editor. This is one story of one city, not a ranking of models.

reputation and trust as of turn 10

In the test recording (10 turns) the council has not voted yet, so the council rows are zero; reputation and trust exist only for the end of the recording.
