AI Founders Leave Bezos-Backed Prometheus to Model Physics
Anima Anandkumar and Benedikt Jenik built a new kind of artificial intelligence.
Most popular AI systems learn from words and try to predict what word comes next.
Their system instead studies how things in the physical world change over time and space.
The company says it processed 5 trillion pieces of data in one test.
This could help businesses design computer chips, operate robots, predict severe weather and study underground information.
The pair had been offered important roles and a large ownership stake in Jeff Bezos-backed Project Prometheus.
They decided to continue building their own company instead.
Prometheus later raised $12 billion in a Series B financing round.
The new company plans to sell its technology to businesses rather than consumers at first.
Anima Anandkumar and Benedikt Jenik launched Accelerated Understanding Inc. after declining a proposed leadership role at Project Prometheus.
The company says its physics-focused AI handled 5 trillion pieces of data in one prompt during testing.
Unlike language models such as ChatGPT, the system uses neural operators to predict physical phenomena across space and time.
Accelerated Understanding is targeting enterprise applications including chip design, robotics, extreme-weather prediction and geological analysis.
Project Prometheus later raised a reported $12 billion Series B and is pursuing AI for manufacturing complex physical systems.
- Who
- AI researchers Anima Anandkumar and Benedikt Jenik, and their company Accelerated Understanding Inc.; Project Prometheus is also involved.
- What
- Accelerated Understanding launched a physics-focused AI model that the company says can process extremely large amounts of data.
- When
- The company was unveiled on Tuesday, August 25; the proposed Prometheus collaboration was discussed in late 2024, and Prometheus raised its Series B in June 2026, according to the article.
- Where
- The company launch was reported from San Francisco; the earlier Prometheus discussions took place at a restaurant in greater Los Angeles.
- Why
- The founders believe AI that predicts physical phenomena can improve enterprise applications such as chip design, robotics, weather prediction and geological analysis.

Business direction
Independent Physics AI
Anandkumar and Jenik chose to keep building Accelerated Understanding independently and focus on enterprise applications for a general physics model.
Prometheus Collaboration
Project Prometheus is pursuing AI designed to automate the manufacturing of complex physical systems.
Role and ownership
Independent Physics AI
The founders did not accept the proposed arrangement and continued developing their own company.
Prometheus Collaboration
The proposed offer would have made Anandkumar the public face and scientific leader, with Jenik as a board observer and both receiving a combined 35% stake.
AI approach
Independent Physics AI
Accelerated Understanding is centered on neural operators that model physical phenomena rather than language.
Prometheus Collaboration
The article does not detail Prometheus's specific technical architecture, but describes its target as manufacturing complex physical systems.
