OpenAI's API pricing page: two "cyber" models appear, four legacy models drop off

OpenAI's API pricing page changed on October 20, 2026: two models were added, four were removed and seven were listed with changed entries. This is the pricing page itself, not an OpenAI announcement, and the page's entries give prices without a unit.

• Added: gpt-5.5-cyber and gpt-5.6-cyber, each listed at 12.5 input, 75 output and 1.25 cached input. The entries say nothing about what the models are or who can use them.
• Removed from the page: gpt-3.5-turbo-instruct (1.5 / 2), davinci-002 (2 / 2), babbage-002 (0.4 / 0.4) and gpt-3.5-turbo-1106 (1 / 2). Removal from a pricing page is not by itself a retirement notice.
• Changed, with the new listing (input / output / cached input): gpt-6-astra 10 / 50 / 1; gpt-5.6-sol 4 / 20 / 0.4; gpt-6-sol 2 / 10 / 0.2; gpt-6.1-sol 2 / 10 / 0.1; gpt-5.6-terra 2 / 12 / 0.2; gpt-6-luna 0.1 / 0.5 / 0.01; gpt-5.6-luna 0.2 / 1.2 / 0.02.
