Unpredictable AI Coding Costs
Developers and teams face runaway, unpredictable token and credit costs from AI coding tools that exhaust budgets mid-project.
In their words
On average at my job there's a developer (sometimes two) who will blow 4k a month in tokens.
I run out of tokens frequently and it’s because I have a lot of work to get done.
quando o limite acaba, voltamos a ser obrigados a programar como nossos ancestrais, e as entregas vão demorar dezenas de vezes mais
Tons of wasted money tbh, I’ve been working on a game within godot that has a lot of the same components. I have both a codex and Claude sub and you get only a few changes in per 5 hour session.
I managed to consume roughly 50% of my weekly allowance in about two days.
In 90mins of fruitless work it used usd13 of credits
at this rate it costs probably the same if not more than paying a senior dev to code by hand
I did a code review on a relatively small pull request and it used like, millions of tokens in a single go.
once they start charging us what it actually costs
If Luna is 1.1x until 272K and 2.2x afterward, the IDE should say exactly that.
it's easy to spend more than a hundred dollars improving a single function, because the model spends so much time investigating before it acts
every time I use it just burns through all my ai credits
Last month we consumed all the subscription credits by the 7th day, and had to top the extra credits up every 2-3 days.
Running two agents at once and having no idea which one ate the budget is the part that actually costs me.

Why those fall short
- burns tokens on rate limit fails, loses work, barely works reliably
- no per-user caps or budget alerts; pool exhausted by heavy users
- no per-session cost breakdown; hard to estimate task cost before starting
- daily caps run out fast with workflows, MCPs and agents
- Copilot sends excessive context and caches poorly, inflating token costs
