Used to spend +/- 50 dollar a day... now heading towards 50 dollar per 2 hours?

After spending over $50 in just a few hours, I am greatly disappointed with Max Sonnet overall. The issues I encountered are exactly the same to those with the regular 3.7 Sonnet and Thinking in the Cursor Composer. It misses obvious information, does not adhere well to specified rules and in-chat instructions and must be reminded of them constantly, its efficiency is, in my experience, very similar to regular 3.7 - the agent needs to be corrected all the time to not deviate even from the accepted implementation plan, that’s already pinned in the conversation context. It has a strong tendency to “simplify” my implementation, which usually (almost always) ends up being a code loss that I simply rejected at review, while my problem still isn’t solved, so it’s a pure net waste of time. I wanted to give the new feature a fair shot, but I will not be using the Max option again.

Also, it was really annoying that even though the developers claimed that the Max option unlocks the full 200K token context window, the chat was constantly prompting me to open a new conversation to maintain high performance, in intervals, I would say, that are exactly the same as when using the regular 3.7.

In summary, I absolutely do not see the Max option to offer me a Smarter Sonnet, only more eager to use tool calls which are charged separately. The effect was greatly disappointing. I am convinced that if I were using a regular Sonnet in the Agent mode, I would basically get the same result without being charged additionally. The option will absolutely bankrupt you, giving very little in return.

To clarify, I would be absolutely okay with the cost that comes with the Max option if it would offer equal value in return. Currently, it absolutely does not.
