The Result
I ran Claude 4.5 Opus through Copilot Agent for an entire day. The total cost? About $10.

My Honest Take
Not bad at all. Actually, it’s insanely cheap.
$10 is roughly the cost of hiring someone for one hour. But with this, I got a full day of code writing, documentation, and bug fixes.
As a Direct Cost
When you think about this as a direct cost for development:
- Hiring a developer: $15/hour × 8 hours = $120
- Claude 4.5 Opus for a full day: ~$10
That’s one-twelfth the cost. And Claude doesn’t get tired, doesn’t need breaks, and doesn’t complain.
Takeaway
AI development tools are no longer “too expensive to use.” With pay-as-you-go pricing at this level, there’s no reason NOT to use it.
This is a game-changer.
