Old Model New Model: $20 monthly credit for frontier model usage at real API rates, with unlimited usage only via "Auto mode" that dynamically selects cheaper or slower models. New Model User Frustration User Frustration Unexpected Charges: Many users hit the $20 usage cap after just a few prompts, especially when using models like Claude Opus 4. Automatic Billing: Users were charged beyond their plan without realizing spend limits had to be manually configured. Limited Premium Access: The only truly "unlimited" access was through Auto mode, which often doesn't route to premium models.
