GPT-5.6 CYBER 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.
GPT-5.6 Cyber costs 2.5x more than GPT-5.5 for the same job — a 1,000-token prompt with a 3,000-token reply runs $0.24 vs $0.10. At 1,000 runs a day, that gap is $4,275.00 a month for identical traffic.

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.
