Open models. Proven on your traffic.

Test a small slice, serve what works, and adapt your model with your own data.

AI investment is growing. Production still takes work.

$37B

Estimated enterprise generative AI spend in 2025. Based on a survey of about 500 U.S. decision-makers and market modeling.

76%

Enterprise AI use cases purchased rather than built internally. Based on the 2025 enterprise AI survey.

$20 vs $1

Illustrative cost per million output tokens: $20 for a frontier API versus $1 for an open model.

Industry spend and adoption source: Menlo Ventures, 2025. Token costs are illustrative, not Kordus results.

What Kordus does

A safer path onto open models.

Canary it.

Send a small share of traffic to an open model before anything else changes.

Serve it.

Run inference on the open model where the canary looks good.

Train it.

Post-train on your own data when you want the model closer to the job.

The product

From a small test to a model you can keep improving.

Canary rollouts

A small slice of traffic, with a way back.

Inference

Open-model serving for the traffic that is ready.

Post-training

Your data, used to push the open model further.

Quality checks

See whether the open model holds before you expand.

Keep what works

Frontier calls can stay on the traffic you are not ready to move.

Your models

Open weights you can keep working on.

Frontier API / Kordus

A frontier API is simple. An open model is cheaper. The gap is the path between them.

FAQ

Questions

What is Kordus?

A way to try open models in production: canary a slice of traffic, serve the model, and post-train it.

Do we have to leave our current provider?

No. Start with a canary. Keep the frontier model on everything else.

What is a canary rollout?

A small share of real traffic goes to an open model first, so you can see quality before you expand.

Do you run inference?

Yes. Kordus can help serve the open model on the traffic you move.

Do you post-train?

Yes. Kordus can help train the open model further on your data.

How do we start?

Request access and tell us which of the three you want to try.
