Whether or not they can be trusted isn't all that relevant when it's still something along the lines of "Insert $1 get $25 in return" even if it's their own rates you're using to measure the value. I'm at ~2.2b Fable 5 tokens in the last 7 days (I ingest/index every session) and napkin math says that's ~$2,700 in usage. I have two max accounts, so $400 a month, divide by 4 to get $100 for this same 7 day period across those two accounts (neither are maxed out for the week, so this isn't even full utilization). I put $100 into the machine and got back $2,700 in fable bucks. Deepinfra would have to have quite the discounted rate to beat that.
