GPT-5.6 Cyber

GA

Purpose-trained cybersecurity model in the GPT-5.6 family, for approved defenders doing authorized vulnerability research, exploit validation and security testing. ACCESS IS GATED: OpenAI states it 'requires separate approval and provisioning' via the Daybreak program, so the published rate is not self-serve. Priced in its own 'Cyber models' table on the pricing page (12.50 / 1.25 cached / 75.00 per 1M, cache writes 15.625) - a table check-price-drift.mjs does not read, because that script anchors on the Standard-tier tables. 400K context, 128K max output, Feb 16 2026 cutoff, text+image in / text out, reasoning tokens supported. The pricing page's long-context columns are '-' for this model, i.e. no long-context tier is published, unlike Sol. 'daybreak-red-latest' is an alias currently pointing here (and 'daybreak-blue-latest' to gpt-5.6-sol); the aliases are stated to re-point as new Daybreak models ship, with pricing following the underlying model. No release date published (null).

GPT-5.6 Cyber by OpenAI costs $12.50 per 1M input tokens and $75 per 1M output tokens ($28.13/1M blended), with a 400K (400.000-token) context window. It is generally available (GA), with a knowledge cutoff of 16 Feb 2026.
