What stands out
What its maker marketed at launch, and what people found later, each with its source.
Small onboard VLA for a home humanoid
160M-parameter vision-language transformer (language embeddings + ViT tokens + proprioception) with a diffusion-policy action decoder, running fully on NEO’s embedded GPU at ~5 Hz, so it works without internet.
Mobile bimanual whole-body manipulation
Combines locomotion with manipulation (bending, leaning, bracing) for retrieving objects, opening doors and navigating the home; learns from both successful and failed episodes.
Voice control via offboard LLM
An offboard speech-to-speech LLM handles conversation and hands tasks to Redwood.
Notes
Ships as NEO’s foundational autonomy; tasks it cannot do are handled by remote human teleoperation, which drew privacy criticism (https://startupfortune.com/1xs-20000-neo-robot-lets-a-company-employee-watch-inside-your-home/). NEO: $20,000 Early Access ownership or $499/month subscription, $200 refundable deposit, “US deliveries start 2026” (order page checked 2026-09-29). 1X opened its Hayward, CA NEO factory on 2026-04-30 (10,000 units targeted in year one); as of mid-July 2026 no verified customer home delivery had been reported and we found none by 2026-09-29.
