Every month it is the same trap. A reasoning model gets upgraded at the same price per token, then quietly burns three times the output tokens. Or the new version costs 40% more and deprecates its predecessor in four months. Are you growing 40%? Making three times the revenue? Sarah Sachs, who leads AI engineering at Notion and negotiates its model contracts, says no, and that is why she treats every vendor as a competitor. Buy tokens from a lab that also sells the first party product and you are paying a markup on a markup for something you cannot defend, with no exit if you lock yourself to one provider. Her answer is to stop winning on token economics and win on product: data flywheels, orchestration, and staying model agnostic so optionality stays your leverage. Notion's auto model quietly routes about 75% of traffic and swaps providers underneath, her AI Switzerland approach; triaging an email inbox on Opus, she says, rips off the customer and Notion both. Route by cost per capability per second, not per token; use open weight models for the moderate middle; reach for CPUs over GPUs, because you do not need an LLM to turn a CSV into a PDF. The final stretch turns to the lethal trifecta and a live demo of Notion agents scoping a task, tagging in teammates, and opening a PR.
