> I still don't understand how people justify the cost of using API keys vs. subscription

Like a big white truck or a 600mm lens, expensive gear should be purchased by an employer. I think most folks talking about API access are getting it through work/self-employment.

Anthropic needs to retune their personal plans. Opus is the Amelia Bedelia of models. Maddening! I shelled out $100 for Fable to drive Opus and finish a personal project, but that's probably my last time loading up on usage credits. I put a second $100 towards API credits so I could dink around with API access and understand conversations like these.
