After my usage limits reset, I sent *one* prompt. Within 12 minutes, it ate 21% of my 5-hour limit. I am on the 5x ($100) plan, and before Opus 4.8, I can barely remember ever hitting my limits.

I looked into the math behind it, and the token burn is absolutely absurd. If you have the 1M context window and UltraCode turned on, it spawns 10-15+ different agents simultaneously. Because each parallel sub-agent reads that massive 1M context window independently, you are effectively running a dozen heavy Opus calls at the exact same time.

While that sounds like it would be incredibly efficient and powerful, it honestly wasn't. It felt like it spawned a ton of agents and just waited on them to respond simply because it *could*, not because the prompt actually needed that much parallel computing. i still waited a total of 20 minuets for this one prompt to complete, and the feature wasn't even properly working upon completion

I understand the token math, but spinning up unnecessary agents just feels like Anthropic's attempt to get 5x users to burn through their limits and start paying more. Be careful combining Opus, 1M context, and UltraCode unless you want to nuke your limits in a single prompt. Has anyone actually seen the cost make it worth the time savings? it's possible i could just be failing to see the use case. 

Claude's new usage limits are insane.
