Heads up: GitHub Copilot is changing how it bills us on June 1st
If you use GitHub Copilot for heavy lifting, you need to check your billing dashboard before June 1st, or you might be in for a nasty surprise next month. GitHub is officially killing the old flat-rate PRU (Premium Request Units) model and switching to usage-based billing with AICs (AI Credits).
Here is exactly what is changing and how it affects your wallet.
The Switch: PRUs ➡️ AICs
Under the old system, you paid a flat rate per prompt, regardless of complexity. Starting in June, the meter runs on compute tokens.
The Good News: Standard, inline autocomplete (the grey ghost text that appears while you type your code) remains 100% free and unlimited. It does not consume your AI Credits.
The Catch: Heavy interactive features—like Copilot Chat, Cloud Agents, or generating massive blocks of code using frontier models (like Claude Opus or GPT-5.x)—will now burn through your AIC allowance fast.
The Plans & The Math
If you are on the standard $39/month Copilot+ plan, you get an allowance of 7,000 AICs included.
Once you burn through that, you are charged $0.01 for every additional AIC. If you heavily rely on Copilot Chat to refactor complex components or scaffold large features, you can easily rack up hundreds of dollars in overages (some previews are showing $150+ in projected additional usage for heavy users).
GitHub is introducing a Max Plan designed for heavy users. It costs more upfront, but it dramatically increases your included credit pool, making it mathematically cheaper than paying the overage penalties on the standard plan.
How to Protect Yourself Now
If you don't want a massive bill next month, take 2 minutes to do this today:
Check your simulation: GitHub has a tool that simulates what your April usage would cost under the new June rules. Check your projected bill here: https://copilot-billing-preview.github.com/
Set a hard budget: Go into your GitHub billing settings and set your overage limit to $0. This ensures that once you hit your 7k AIC limit, the heavy features just pause until the next month, keeping your bill flat. (Remember, normal autocomplete will still work fine!)
Throttle the heavy models: Save the expensive frontier models for complex architectural reasoning, and drop down to lighter models for standard file generation.
Don't let the new usage-based billing catch you off guard next week. Check your preview stats!
A Real-World Example: My Own Usage Simulation
To put this into perspective, I ran my own account through the preview tool. On my current $39/month standard plan, I get the included allowance of 7,000 AICs.
However, because I heavily rely on Copilot Chat and premium models to refactor code and scaffold features, look at how the simulation calculated my April 2026 usage under the new June rules:
April AIC Consumption: 24,486.5 AICs
Included Pool Allowance: -7,000 AICs
Overage Billable Credits: 17,486.5 AICs (billed at $0.01 each)
New Overage Fee: +$174.87
Total Projected June Bill: $213.87
That is an increase of $172.24 over what I usually pay, just for coding exactly the same way I did last month. If I upgrade to the new Max Plan, the simulation tells me it drops the total bill down to roughly $144.87—which is better, but still a massive jump from a flat $40.
Quick question for the group: Who here relies on GitHub Copilot daily, and have you run your usage preview for the June changes yet?
