I guess I got downvoted because people don't believe me that it's cheaper? But I spent $5 a couple days ago in one hour with deepseek v4 in a coding agent. That's way more expensive than a $20/month claude subscription. Even if I hit claude's 5h limit in one hour I can do that many times in a month.
I have a similar experience, however if you spent $5 at these rates you may have an issue with caching in your client.
Can you give some details about your use case. I have been using DS4 very heavily and I can hardly spend more than 1USD per day
