Does any of this sound familiar?
New models ship every month,and I can't tell which one fits our product.

Use what your users actually do as the yardstick.Validate models with your users' responses, not outside scores.
Find the right model for your product in three steps
1. Collect user actions
The Client SDK records user actions such as purchases and return visits.
2. Split your users
The AI gateway splits users across models and prompts to compare them.
3. Compare by model
See conversions and AI call costs side by side on the dashboard.
Sonnet 5.51. Collect user actions
Collect user responses
with one SDK line
Add one line where a purchase or sign-up happens.That action becomes your success metric.
2. Split your users
Change one URL and
ABTO splits your users
Your calling code stays as it is.Users are split by your ratio, and each keeps the same model.
3. Compare by model
Compare outcomes and cost
per model on one screen
Conversion rate and cost per call line up for each model.When outcomes match, move to the cheaper model.

ABTO closes this gap by measuring how real users of a service respond.
Read article (Korean)IT Times
It checks whether revenue or user response improved as much as the added cost, and if a lower cost model gets similar results, teams can consider switching.

They say the service can show, for each feature, which model generated more revenue for the same cost.
Read article (Korean)Platum
When results are the same, teams can gradually shift more traffic to the cheaper model. If the existing model performs better, that difference justifies keeping the current cost.

Unjustified increases in AI costs eventually reach users through higher service prices.

ABTO focuses on the economic value an AI model creates in a real service rather than its absolute performance.

The service lets teams apply a new model to 10% of users first.

Frequently asked questions
What is ABTO?
ABTO is an AI model A/B testing service. It assigns users of the same AI feature to different LLMs or prompts, then compares actual behavior, such as purchases and return visits, alongside AI call costs.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 and Python, 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.
