You were getting reliable five hour quota resets for Opus 4.5 in Antigravity, then the UI suddenly showed a four day wait. This is almost always the new weekly cap taking effect for Pro plans.
Opus 4.5 quota changed from five hour resets to a four day wait in Antigravity
You are a paying Pro user and did not change accounts or settings. The Antigravity team announced generous weekly limits due to high demand, and now your UI shows a multi day cooldown instead of the familiar five hour window.
Symptoms you may see:
The quota banner that previously showed a five hour countdown now reads several days remaining
You can still use lighter models or features but Opus 4.5 is temporarily blocked
No account errors or billing failure messages
If you are also running into thinking limit or short context issues when you do get access back, check this practical guide on fixing the 1024 token thinking cap here: token limit troubleshooting for Antigravity.
Solution Overview
Aspect
Detail
Root Cause
A new weekly quota cap for Opus 4.5 is now enforced. Your usage exceeded the weekly allowance, so the UI shows the next reset at the end of your current weekly window.
Primary Fix
Wait for the weekly reset or switch to a different model or mode that still has available quota.
Complexity
Easy
Estimated Time
Two minutes to apply. The reset itself completes on the next weekly window boundary.
Fix the weekly cap cooldown and regain access quickly
Step by Step Solution
1. Confirm you hit the weekly cap
1. Open Antigravity and check the quota banner on the Opus 4.5 model card or the usage page in account settings.
2. If it shows a multi day countdown, you have reached the weekly ceiling and must wait for that reset window.
2. Identify your reset window
1. Note the exact time shown in the countdown. Weekly caps are typically a rolling seven day window or a fixed schedule per account region.
2. Create a calendar reminder for that timestamp so you can resume work as soon as the window resets.
3. Switch to an available model or feature
1. In the same project, select a lighter model or alternative mode that still has quota.
2. If you only need a draft or quick check, run it on the smaller model and reserve Opus 4.5 for final passes after reset.
4. Reduce high cost operations until the reset
1. Batch non urgent runs and disable auto retries that can multiply token usage.
2. Shorten prompts, prune context, and reduce system instructions while you are on a limited model.
5. Verify subscription status and billing
1. Open billing in account settings and confirm your Pro status is active and payment is current.
2. If the plan lapsed or a charge failed, caps can be stricter. Resolve billing and recheck the quota banner.

Alternative Fixes and Workarounds
Request a quota review or plan adjustment
If available in your region or plan, submit a support ticket requesting a quota evaluation for your use case. Provide your project ID, typical daily usage, and impact.
Distribute workloads across time and projects
Split large tasks across multiple days so daily clusters do not trigger the weekly lock early. Keep a separate project for exploratory runs to protect production quota.
Cache and reuse intermediate outputs
Save plan drafts and tool outputs to avoid re running identical prompts.

Troubleshooting Tips
Confirm you are on the intended workspace since team workspaces can share quota.
Sign out then sign back in to refresh the UI quota banner.
Try a different browser profile in case of a cached banner.
Check for scheduled maintenance or a regional spike that may temporarily tighten limits.
If the countdown increases or looks incorrect after the expected reset time, capture a screenshot and contact support with the project ID and timestamps.
Best Practices
Spread heavy runs across the week to avoid crossing the weekly ceiling in one burst.
Monitor usage after large sessions and stop before the lock, then continue after the reset.
Prefer smaller models for iteration and reserve Opus 4.5 for final quality passes.
Keep prompts concise and avoid unnecessary context to reduce token consumption.
Disable automatic retries that can silently burn quota on failures.
The sudden shift from five hour resets to a multi day wait is the new weekly cap doing its job. The fastest fix is to wait for the weekly reset and use a smaller model in the meantime, then pace your heavy runs through the week to avoid hitting the ceiling again.
