Overview

Cynos is a Cyber Inference Platform purpose-built to understand cybersecurity tasks, select the best-fit open or closed model, and evaluate every result.

If a result falls short, Cynos retries the task with additional guidance or escalates it to a more capable model. This makes it possible to deliver frontier-grade cybersecurity outcomes at a fraction of the cost.

Why Cynos?

Identify the best-fit model - Cynos first identifies what kind of cybersecurity work the request represents. It considers the task, its complexity, the capabilities it requires, and the quality threshold the result must meet and chooses the best-fit model for that task.
Improved Accuracy - Combination of Domain Expert Judges and fine-tunes models assist in iterative self improvement to deliver improved accuracy.
Reduce Inference Costs - Automatically routes to the cheapest best-fit model and/or provider. No more overpaying for simple tasks.
Built-in Resiliency - Automatically routes to the alternate best-fit model and provider in case of failutre.

Getting Started

Create a project - Register via the Cynos management API or console
Get a virtual key - Create an sk-cy-* key scoped to your project
Make requests - Send OpenAI-compatible requests to the inference endpoint using your virtual key
