Which models does Cruxy use?

Three: Epos for speed, Saga for balanced everyday work, and Canto for deep reasoning over long context. Set the model to auto and Cruxy picks one by the size of the request, or choose one yourself.

How much does Cruxy cost?

Cruxy is free to start. Paid plans are Core ₹399, Advanced ₹1,499, Pro ₹8,999 and Max ₹17,999 a month, in INR with GST included. For a team, contact us.

Is Cruxy OpenAI-compatible?

Yes, for chat. api.cruxy.ai/v1 serves the OpenAI-compatible chat completions and models endpoints, so existing SDKs and tools work for chat by changing the base URL and key.

What happens to my data?

Your data is not used to train the models, and you can review and delete your memories at any time.

What does Coming soon mean?

It is not available yet. Anything marked Live works today. Leave your email and we will tell you when each one ships.
