I’m genuinely confused and pretty frustrated right now, so I’m hoping someone here can explain what’s going on. I’ve been using this for two days , and I’m not a Claude Pro or Max user I’m using the Antigravity student offer with the 1-year Google AI Pro plan , where I get 1000 AI credits per month . Also, until now I had mostly been using Claude Sonnet . For the last 2 days , I thought I’d try Opus through Antigravity and see how it handles the same kind of work. So I gave a prompt to Claude Opus 4.6 through Antigravity to download Indian market data. It wasn’t anything wild from my side, just a data download workflow. The agent kept running for around 20 minutes , doing its thing. Then suddenly… it just stopped. When I checked the AI credits activity, it showed a -761 deduction in a single entry . Like seriously… 761 out of 1000 monthly credits ? What makes this even more confusing is that I did something similar on the first day too , but that time the credit cut was much smaller . This time it suddenly jumped to a huge amount, and I honestly don’t understand why. The screenshot also shows multiple recent deductions under “Google Antigravity hourly activity” : -761 -7 -90 -130 So it looks like the usage is being counted in chunks, not just as one simple prompt. But still, the 761 hit feels way too much for what I thought was just one run. Now I’m basically left with very little credit, and I’ll probably have to wait almost a week or more before I can even try building anything properly again. That’s honestly super frustrating because: I didn’t expect one run to consume this much I didn’t even get a proper usable result And now I’m just stuck doing nothing I’m not blaming Claude or Antigravity directly because maybe there’s something I don’t understand here. That’s actually why I’m posting I want to know if: this is normal behavior for Antigravity agent runs there’s some hidden cost factor like retries, background steps, or failed tool calls or something actually went wrong Also, has this happened to anyone else? Like a huge sudden credit drain for what felt like a single prompt? submitted by /u/Soggy-Parking5170
