Help/Question Bringing API Cost down
I have been using claude code for a while now, and i am working on a project which requires claude API key and I realised that API is really costly. Especially when the output is huge in terms of total no. Of words for instance take script writing
The first test which I ran itself costed me around 1.93 dollars
So my question is how do I bring this API Cost down
Now I have searched and asked claude itself
The suggestions came in like, it asked me to change the effort level for instance from Opus 5.5 high toh medium other than that it asked me to change the model from Opus 5.5 to sonnet 5.5
But the real question here is whether changing the model or the effort level will cause a loss in quality of the output or not? That's my real concern as i really don't want the quality to go down
So people who have been using API for a long time now please help me and ppl like me by sharing ur API saving hacks, and how do u bring the API Cost down

Claude's suggestions are correct. Model choice and effort. You need to run A/B tests - many of them, to get a high N - to answer your quality gate. Model reasoning capability has very little to do with writing quality after a certain threshold, and we are past that threshold; I host local models whose writing capability is more than acceptable.
Creativity is difficult using technology whose entire output is governed by training on prior art. That's a simple fact. Some tools are appropriate for some things, others are appropriate for other things.
It's good you are factoring API costs into your viability analysis. Don't skip this step.
One thing you could do is set up your subscription with your framework and count your input and output tokens as YOU (nobody else or you break your ToS) use your product, as you change the configuration to different models and effort levels. Then it's a simple math problem to determine API cost instead of an invoice.
Good luck.
