Spirit AI releases Spirit-v1.5 fine-tuning code

Apr 1, 2026 · Research Publication · Spirit AI · Humanoid

Key points

  • Spirit AI updated the Spirit-v1.5 repository in April 2026 with fine-tuning code, separating the training release from the January initial model and benchmark release.
  • The repository documents training requirements, dataset loading, distributed training utilities, and a fine-tuning launcher for adapting Spirit-v1.5 to robotic manipulation datasets.
  • The release matters because it makes Spirit-v1.5 more reproducible as a developer resource for embodied-AI research rather than only a checkpoint and benchmark artifact.
