Value by kind of work

Turns of mixed coding work the allowance covers in a month, each kind on the plan’s cheapest model that is good enough. How this is worked out.

Work mix	Turns a month	Per dollar
Light only (100% light)	20k–37k	200–375
Mostly light (40% normal, 60% light)	10k–19k	101–189
Balanced (5% frontier, 15% hard, 60% normal, 20% light)	1.5k–2.8k	15–28
Mostly hard (10% frontier, 40% hard, 40% normal, 10% light)	804–1.5k	8–15

On the balanced mix: frontier work on GPT-6.1 Sol (max reasoning), counting 4% of a turn; hard work on GPT-6.1 Sol (max reasoning), counting 50% of a turn; normal work on GPT-6.1 Terra (xhigh reasoning); light work on GPT-6 Luna (max reasoning), counting 55% of a turn.

How the figure was obtained

The measured Plus range times 10. Allowances were doubled on 29 October 2026 and no measurement exists since.
