Ecosia drops Mistral for Chinese open-source AI models

KEY FACTS

  • German search engine Ecosia has dropped France's Mistral in favor of Chinese open-source AI models.
  • CEO Kroll said Mistral's quality lags a full year behind competitors.
  • Ecosia only switched from OpenAI to Mistral in May of this year, and frequently hit server overloads during the partnership.
  • Ecosia now works with Melious, using the Qwen, GLM, and Kimi models.
  • After the switch, Ecosia cut costs in half and gained performance improvements.

PHYSIX OBSERVATION

European companies are starting to vote with their feet, treating open-source models as a shortcut to catch up with the frontier rather than burning money on in-house development. Chinese open-source models are entering the European market on price-performance, and if regional stars like Mistral cannot resolve doubts about stability and neutrality, customer churn will accelerate. For users, swapping the AI underbelly of search could improve both experience and cost.
