  • The repository says Spirit-v1.5 ranked first on the RoboChallenge Table30 benchmark as of January 11, 2026, and links the Hugging Face model release.
  • The release matters because it gives Spirit AI a first-party model artifact behind its embodied-intelligence stack and provides a public benchmark path for the Moz1 product story.
