GPT-5.6 VS GPT-5.5

OpenAI vs OpenAI, in USD per million tokens, cross-checked daily against the public pricing dataset. Same jobs, both meters running.

THE VERDICT

1.5x

GPT-5.5 costs 1.5x more than GPT-5.6 for the same job — a 1,000-token prompt with a 3,000-token reply runs $0.10 vs $0.06. At 1,000 runs a day, that gap is $930.00 a month for identical traffic.

SIDE BY SIDE

	GPT-5.6 →	GPT-5.5 →
Vendor	OpenAI	OpenAI
Input / MTok	$4.00	$5.00
Output / MTok	$20.00	$30.00
Output multiple	5.0x	6.0x
1K prompt + 3K reply	$0.06	$0.10

SAME JOB, BOTH BILLS

Scenario	GPT-5.6	GPT-5.5	Gap
A typical prompt	$0.02	$0.03	1.5x
A 20-turn conversation	$0.10	$0.14	1.5x
Summarizing a 10-page document	$0.10	$0.14	1.4x
One agent run	$0.25	$0.37	1.5x
A code review request	$0.08	$0.12	1.5x

Output sizes use the same editorial ratios as the Burn Calculator. Estimates, not invoices — and price is not a benchmark: the cheaper model is only a bargain if it does the job.

SETTLE IT WITH YOUR OWN PROMPT

Paste a real prompt into the Burn Calculator and see what it costs on GPT-5.6, GPT-5.5 and the other 23 models on the board — plus how much of it is waste either way.
