The honest brief
1X
Targets the home, not the warehouse — a consumer humanoid with an onboard VLA and a teleop-assisted learning loop.
- Redwood VLA runs onboard on NEO's GPU
- Consumer pricing: $20k or $499/month
- Human teleoperation accelerates skill learning
- Ships from 2026 — unproven in real homes
- Teleop raises in-home privacy questions
- Narrow task repertoire at launch
- No developer API or platform yet
Physical Intelligence
Open-sourced its flagship robot VLA: π0's code and weights ship in the public openpi repo, rare for a frontier lab.
- openpi repo runs and fine-tunes locally
- Cross-embodiment VLA foundation model
- Built on a pretrained vision-language model
- Demonstrated dexterous real-world tasks
- Research artifact, not a turnkey product
- Needs robot hardware and ML expertise
- Linux/local deployment only
When to pick which
Both cover Vision-language-action, Robot foundation model, and Dexterous manipulation.
Pick 1X if you need Voice agent and Bipedal locomotion.
- Voice agent (secondary capability)
- Bipedal locomotion (secondary capability)
Pick Physical Intelligence if you need Fine-tuning / training and Imitation learning.
- Fine-tuning / training (secondary capability)
- Imitation learning (secondary capability)
1X leans on Vision-language-action as a headline capability; Physical Intelligence treats it as secondary.
- Vision-language-action (primary capability)
