No. It's a tiny expense. I mostly use GPT 4.1 Mini for what I'm doing as it's the best balance between results and cost, but Gemini Flash can do the job just as well for a little less if I need it.

As other commenters have mentioned, a firehose can mean many things. For me it might be thousands of different reasonably small things a day which is dollars a day even in the worst case. If you were processing the raw X feed or the whole of Reddit or something, then all of your questions certainly become more relevant :-)
