What is GPT-5.6 Cyber?

Specialized, approved access

GPT-5.6 Cyber is OpenAI’s purpose-trained cybersecurity model for authorized vulnerability research and security testing. Access requires separate approval and provisioning through the publisher’s program. A general OpenAI API account does not establish that this model is enabled.

Documented interface

The first-party profile lists a 400,000-token context window and a 128,000-token output maximum. It documents streaming, function calling and structured outputs, with several tools available through the Responses API. The model is an alias for the publisher’s advanced cybersecurity models, so record the returned identity and configuration when reproducing an evaluation.

The starting text rates are $12.50 per million input tokens and $75 per million output tokens. Tool-specific charges and current program conditions need to be checked separately. A specification table does not describe a complete research-run bill.

Evaluate within the approved workflow

Useful evaluation cases include triage quality, whether a finding reproduces in an authorized test environment, and the evidence needed to validate or reject it. Keep model findings separate from confirmed vulnerabilities. Measure false positives, analyst time and reproducibility alongside any task score.

The model’s intended role and gated access make it a specialized comparison candidate. For ordinary coding or document tasks, compare the general model families instead. This profile summarizes the publisher’s documented interface and access conditions; it is not an independent security evaluation.

Tasks and inputs

GPT-5.6 Cyber is listed for Image-text-to-text, Text generation. It accepts text, image and produces text. Use the publisher’s input format and preprocessing for your chosen deployment.

Capacity and cost

Documented limits: 400K context and 128K maximum output. The listed route charges $12.50 input and $75.00 output per million tokens. Measure a completed task using the prompts, documents and tools your application will use. Include reasoning and retries in the result.

Choosing a deployment

Use the model identifier and account requirements for the selected API route. Confirm its request limits and output format with one complete task before connecting a larger workflow.
