Same prompt, every model

Longer conversation
| Turn | Input tokens sent | Reply tokens, reread later |
|---|
Each turn rereads the whole conversation, so input grows with every reply. Turn 1 is your message. Each reply is billed once as output, then sent again as input on every later turn. Later turns use sample follow-ups and a sample reply, so the pattern matters more than the exact numbers.
