OpenAI says its Forward Deployed Engineering (FDE) team embeds with customers to close the “deployment gap,” turning model capabilities into repeatable production systems. Published examples include John Deere, semiconductor work with ~48% time saved and 22% median gains, and Tax AI processing 7,000
NVIDIA presents Kumo Relational, a pre-trained relational foundation model that predicts directly on databases without task-specific training or feature engineering. The company reports it beats supervised baselines across 41 tasks and scales to databases with 500B+ rows.
Spotify reported 788 million monthly users and nearly €5 billion in third-quarter revenue. Co-CEO Gustav Söderström says the company is positioning Spotify to be the media service that AI assistants access for music and audio needs.
