Pay as you go. I never spent more than $10/month working on my side project (usually a few evenings per month).

I have the enterprise plan and get to use it for both work and some personal stuff.

I mainly use it for side projects and doing research for writing stuff on my blog.

I use Opus 4.6 with claude code 1M context and consistently use up 150-200$ worth of token per day. I wonder how do you manage to do anything with a 10$/mo program.
