AI Coding Token Cost Overruns
Developers using AI coding assistants and agents burn through token quotas and budgets unpredictably, hitting limits mid-task and losing productivity.
In their words
Fable burns through the 5-hour window on exactly one chunk of work.
it blew through about 5USD in 2 hours of usage
A developer tool should not make you wonder whether a small refactor is going to use 2% of my monthly credits, 10%, or almost half your month.
Even a simple task like pushing and deploying what it has built is now consuming over 4% of my weekly limits
em duas conversas ele consumiu o limite semanal todo
1 hour of coding and I hit my five-hour limit.
the conversation context kept growing, my weekly quota disappeared quickly, and I wasted several reset coupons
Every query timing out and it kept suggesting i add caching instead of just telling me i was running unindexed queries
it is DESIGNED TO RUN FOR 30 mins TREATING YOU LIKE AN IDIOT assuming you're completely wrong about everything
how the HELL im gonna learn this thing without spending nearly my rent on the api prices?
I use about a billion tokens a month on codex and if I can save 10 bucks I will.
I just pick whichever one doesn't feel stupid lmao.
Had to create a separate account and pay for another max plan to unblock myself temporarily
the limits are so strict that sometimes I can't use them for 30 minutes or more

Why those fall short
- no stop condition; agent keeps verifying and re-running scripts
- tried 3 times to build a token usage tracker and got nowhere
- Fable uses entire weekly limit in a day and a half
- no prompt caching discount on subscription usage; polling loops repeat context
- Fable burns 5-hour window on one chunk; review pass eats tokens
