On-device AI startup Underdog is partnering with NVIDIA to bring a fully local personal AI to RTX Spark laptops, and is giving away the first unit signed by NVIDIA founder Chris Malachowsky.
Key points:
- The product runs entirely on-device for mail, calendar, meetings, and web — no datacenter involved.
- Its Underdog Saluki 27B model claims parity with Claude Opus 4.6 (the top model six months ago), fits in under 8 GB, and hit 370k+ downloads in its first week.
- A model/chip co-designed inference engine uses CUDA megakernels to reach datacenter-class speeds (20+ tok/s) on the Spark.
- Entry requires retweet/like, signup, and following the account.
