Find the right model for your product in three steps

  1. 1. Collect user actions

    Record the actions you count as success, like purchases and return visits.

  2. 2. Split your users

    Split users so each group gets a different model or prompt.

  3. 3. Compare by model

    Compare conversion and AI cost for each model on the dashboard.

1. Collect user actions

First, decide what
counts as success

Add one SDK line where a purchase or sign-up happens.Those records are what you compare models on.

2. Split your users

Split your users and
let each group try a different AI

Just point your model calls at the ABTO gateway.Send part of your traffic to the models you want to test.

3. Compare by model

See which AI fits best
by real results

See results and cost for each model at a glance.When results are close, you have a reason to move to the cheaper model.

Frequently asked questions

What is ABTO?

ABTO is an AI performance analytics tool. It shows how actual behavior, such as purchases and return visits, changes when you switch LLMs or prompts, alongside AI call costs, by giving the new option to a share of users of the same AI feature first.When results are the same, you can move traffic to the cheaper model to reduce LLM costs.

Which AI models can I compare?

You can call and compare models from OpenAI, Anthropic, Gemini, DeepSeek and Kimi the same way.Set up to five variants and choose what share of users each one gets.

Do I have to rewrite my code?

No. Point the OpenAI SDK you already use at the ABTO gateway and add a few headers to each call.ABTO also provides server SDKs for Node.js, Python and Java/Kotlin, plus SDKs for browser JavaScript, Android, iOS and Flutter.

What happens to my API keys and provider contracts?

Your existing provider contracts and API keys remain unchanged.API keys are passed with each request but are not stored in the gateway's call records.

Do I have to switch every user to a new model at once?

No. A new variant is saved at 0%. We recommend assigning 10% of users to it first, checking the results, then increasing that share.When you send a device ID, each user keeps the same variant until you change the split, and you can roll back in seconds if something goes wrong.

Can I try it for free?

Yes. The Free plan lets you make up to 30,000 AI calls over 30 days without registering a payment method.Going over the limit does not affect your connected service.
