# AlphaNIST: robot AI research model

AlphaNIST is a 2026 [NVIDIA](/companies/nvidia.md) and [University of Washington](/companies/university-of-washington.md) research framework that trains a single contact-rich robotic assembly policy in simulation across all 20 NIST Assembly Task Board #1 tasks using only sparse binary completion rewards, without demonstrations or per-task tuning.

- **Slug:** alphanist
- **Type:** Research model
- **Maturity (DEPLOY ladder):** Research
- **Open source:** no

## Architecture

End-to-end RL (PPO-style) with sparse binary task rewards, beta sampling over start states, and multi-task joint training; also trains multi-pair episodes rewarded only when all pairs are complete.


## Key facts

- **NIST board sim success (paper, Oct 2026):** One policy trained from scratch across all 20 NIST Assembly Task Board #1 sim tasks with sparse binary rewards only; 98.2% overall training success, no demos or per-task tuning.
- **Multi-pair chaining (paper, Oct 2026):** Same framework trains policies to finish ten assembly pairs in one episode; reward only when all pairs complete; no prescribed order.

## Common questions

### What is AlphaNIST?

AlphaNIST is a 2026 [NVIDIA](/companies/nvidia.md) and [University of Washington](/companies/university-of-washington.md) research framework that trains a single contact-rich robotic assembly policy in simulation across all 20 NIST Assembly Task Board #1 tasks using only sparse binary completion rewards, without demonstrations or per-task tuning.

### Is AlphaNIST open source?

No. AlphaNIST is recorded as proprietary on the DEPLOY registry. Model weights and source are not publicly available.

### What type of AI is AlphaNIST?

AlphaNIST is a research model, built on a End-to-end RL (PPO-style) with sparse binary task rewards, beta sampling over start states, and multi-task joint training; also trains multi-pair episodes rewarded only when all pairs are complete. architecture on the DEPLOY registry.

### What is AlphaNIST's maturity stage?

AlphaNIST is at the research stage on the DEPLOY maturity ladder. Research stage means active development without commercial deployments on file.

### Which robots run on AlphaNIST?

No robot models on the DEPLOY registry are recorded as running AlphaNIST. DEPLOY wires brain-to-model connections only when the wiring is verifiable from primary sources; absence may reflect pre-deployment or unverified manufacturer claims.
