Antigravity Ultra: From "Too Good To Be True" to Dirty Business
Credit where it's due: in my first ~month on Antigravity Ultra, I easily burned through $4,000/month in Claude tokens for a flat ~$200. Unlimited Opus 4.6 with extended thinking and planning mode, I thought I hit the lottery. I spammed it for as long as I could stay awake.
I noticed they had some "AI Credit Overage" system, but I had 20,000-25,000 credits sitting there meant for other Google services I didn't use. No concern.
Then one day, a usage cap. A cap? I pay for unlimited. It reset in a few hours, fine, no big deal. I also realized the cap was eating into those overage credits. Still cool, I had tons!
Then it got worse. Cap hit within 30 prompts. Then 20. Then 10. Now it can hit in a single prompt.
This actually sharpened me. I got obsessive about token optimization, implemented the caveman skill and adopted James Van Clief's "Interpretable Context Methodology: Folder Structure as Agentic Architecture" (shoutout James, your workflow plus Antigravity's artifacts plus caveman is genuinely overpowered. Happy to co-write a follow-up paper, there's real research here). For perspective, and as a side tangent, I imagine directory structures as binary trees whose nodes contain context markdown files, and it's the agent's job to deliberately traverse the tree to append only the files holding the context it needs.
None of it matters anymore. Today I'm speaking out:
- Once you drop below 50 AI credits, your usage cap drops from 100% to 20%, and the last 20% is unusable. (Screenshot attached.)
- I hit the ceiling in one prompt today. My workflow generates 2,000–4,000 lines of code in minutes via ICM + caveman ultra. One prompt killed the day.
- The cap resets every 24 hours. So one prompt doesn't just end today, it ends tomorrow too.
I don't care what terms I clicked. Selling "unlimited," then mid-billing-cycle redefining it into something unrecognizable isn't a policy change — it's dirty business. Imagine paying for a gym membership and being told the next day it was actually a day pass. That's where we are.
Give me what I paid for until the billing period ends. That's the floor. Anything less is legal theft hiding behind some Terms of Service, and it deserves to be called out and shamed.
