Developers · Relay — token efficiency as the edge
The AI tutor that never wastes a token on a simple question.
Satya Nadella put it plainly: token efficiency is the new competitive edge. We built LemonSugar Ai around that idea.
Most AI apps send every question — "what's 12 × 8?" and "explain Bayes' theorem" — to the same expensive model. You pay for it. So do the students who need help.
LemonSugar Ai routes each question to the cheapest model that can answer it correctly. Fast questions go to fast models. Hard reasoning goes to reasoning models. You see which model answered, and how much you saved, on every reply.
Every question is scored and sent to the right model — not always the biggest one.
Every reply shows which model answered and the per-reply savings vs. always using GPT-class models.
Weekly transparency page shows cheap-match rate and dollars saved across the whole app.
No hidden models. No "best model always." Just the right help, right now.
