Decision models go mainstream: TypeSafe raises $870M, Microsoft ships Decision-1

TypeSafe AI raised $870M at a $7.5B valuation for Jev, its non-text model returning calibrated probabilities, 24 days after a $200M seed. Microsoft launched Microsoft-Decision-1 in Foundry, post-trained from Alibaba's Qwen3.5-9B, at $0.042 per million input tokens. AWS, Cloudflare, and OpenAI have shipped rival decision models in the last two weeks, making the agent stack's judgment layer its most crowded battleground.
