What ABTO does
ABTO sends a share of the users of one AI feature to a new model first, then compares outcomes such as purchases and sign-ups against the current model, side by side with cost. If the outcomes match, that is a reason to move to the cheaper model. If the current model wins, that is a reason to keep paying for it.
Point your existing OpenAI SDK at the ABTO gateway and you can call OpenAI, Anthropic, Gemini, DeepSeek and Kimi models the same way. Contracts and API keys with model providers stay with you.
What is free
The Free plan needs no card and covers up to 30,000 AI calls over 30 days.
The leaderboard and the AI model finder on this site are free tools that need no sign-up. The leaderboard compares price and latency by model, and the model finder suggests a model for your product after a few questions. The product itself is the dashboard that splits users across models and compares outcomes.
Who we are
ABTO was founded by three people who were building AI services in the 17th cohort of AI·SW Maestro, a Korean software talent program. The company is based in Yongsan-gu, Seoul.
