Helix 2.5 is a neural network by Figure AI for controlling the humanoid robot Figure 03. It was introduced on September 17, 2026 and is pretrained on "Index," Figure's large-scale dataset of human behavior. The model performed cleaning, towel-folding, and bed-making tasks in 30 previously unknown households in the Bay Area without location-specific training, Fine-Tuning, or adaptation, achieving a 56% success rate (237 of 420 attempts) compared to 9% without Index pretraining. Neither model weights, API, nor an official price or sales launch have been published; it is a research/demonstration system without public availability.
