# Figure Helix 2.5: humanoids do chores zero-shot in 30 never-seen homes

Figure's Helix 2.5 (2026-09-17) completed 237 of 420 trials (56%) of tidying, towel folding and bed making in 30 rented Bay Area homes it had never seen, with no data from those homes; the same model trained from scratch (no Index human-video pretraining) managed 9% — a 6x gain from pretraining on human video.

## Key facts
- 30 unseen Bay Area homes; 420 trials across 3 whole-body tasks; 56% zero-shot success (237/420)
- Baseline without Index pretraining: 9%
- Used half as much robot adaptation data as Helix 02
- No single evaluation task >1.90% of pretraining data
- Human-to-robot transfer scaling law: forecasting error 0.54% across an 8x data range
- Figure committed $3.5B of compute for Helix training (partnership with Nscale, early Sept 2026)

## What happened

Figure rented 30 homes and sent Figure 03 robots running Helix 2.5 in cold. Tasks: tidy a living room (13-15 toys into a basket), fold all towels, and make a bed (pillows placed, comforter corners aligned and smoothed).
The key variable was initialization from a checkpoint pretrained on Index human video. Figure also reported a predictable scaling law for human-to-robot transfer.

## Why it matters

This is among the strongest public evidence that robot foundation models scale with human video, and that humanoids can generalize to unseen real homes — a core prerequisite for home robots. Results are company-reported.
