Exploring Jev for AI-Driven QA with agent-device
New article: Jev is a model from TypeSafe that chooses between predefined options instead of generating text. We paired it with agent-device to explore what that approach could mean for AI-driven QA: reading app state, selecting actions, and checking the result. We walk through our proof of concept, how the two tools work together, and a recorded run that took 14 seconds and cost $0.0023 in model inference.
SpaceX Acquires AI Coding Startup Cursor in $60B All-Stock Deal
Days after its historic IPO, SpaceX has signed a definitive agreement to acquire AI coding startup Cursor (parent company Anysphere) in an all-stock deal valued at $60 billion. The reverse triangular merger, announced in an SEC Form 8-K filed June 16, 2026, will see SpaceX's subsidiary X67 Inc. merge into Cursor, which will become a wholly owned SpaceX subsidiary. The purchase price is paid entirely in SpaceX shares, not from the $85.7 billion IPO proceeds. The deal preempted a $2 billion funding round for Cursor that would have valued it at $50 billion, backed by Andreessen Horowitz, Thrive, and Nvidia. The acquisition supports Elon Musk's strategy to position his AI division, built around xAI (which merged with SpaceX), against leading labs Anthropic and OpenAI. Closing is expected in Q3 2026, pending regulatory approvals.
