AI Weekly Issue #543: Google is the latest tech giant to chase TypeSafe's 8-week-old Jev
This issue is about decision models, a new kind of AI model that does not write text. You give it an input and a fixed list of answers, and it returns the best answer with a probability, in milliseconds. TypeSafe AI released the first one, Jev, on September 15. On Wednesday Google released its own,
after OpenAI and Microsoft did in October, and all three charge $0.10 or less per million input tokens and nothing for output. Shanghai AI Lab says its 4B model beat Jev on its tests, and Microsoft built its model on Alibaba's Qwen. Chatbots still score a little higher on the hardest decisions, at 15 times the cost. In the middle: on Vercel's gateway, decision models took one in four AI requests in October.
