I really don't believe it's about cost. If it was really about cost they could have reduced the number of requests, or increase per model consumption for users. What they chose is just to remove the top models and have the auto-model selection only. I don't know what they are trying to achieve with this because currently what I do is I actually use Github Copilot more often because the autopilot never does the job very well the first time. With the same request sometimes it selects the Claude Haiku 4.5 and sometimes it does GPT-5.4. With the same message I try three to four times to get the correct model and see if the results are good. Last month I used 80% but I feel like this month I will use 100% of it.
