LLM Summary:CHAI is UC Berkeley's AI safety research center founded by Stuart Russell in 2016, pioneering cooperative inverse reinforcement learning and human-compatible AI frameworks. The center has trained 30+ PhD students and influenced major labs (OpenAI's RLHF, Anthropic's Constitutional AI), though faces scalability challenges in preference learning approaches.

Overview
Section titled “Overview”The Center for Human-Compatible AI (CHAI) is UC Berkeley’s premier AI safety research center, founded in 2016 by Stuart RussellResearcherStuart RussellStuart Russell is a UC Berkeley professor who founded CHAI in 2016 with $5.6M from Coefficient Giving (then Open Philanthropy) and authored 'Human Compatible' (2019), which proposes cooperative inv...Quality: 30/100, co-author of the leading AI textbook Artificial Intelligence: A Modern Approach. CHAI pioneered the “human-compatible AI” paradigm, which fundamentally reframes AI development from optimizing fixed objectives to creating systems that are inherently uncertain about human preferences and defer appropriately to humans.
CHAI has established itself as a leading academic voice in AI safety, bridging theoretical computer science with practical alignment research. The center has trained over 30 PhD students in alignment research and contributed foundational concepts like cooperative inverse reinforcement learning, assistance games, and the off-switch problem.

Risk Assessment
Section titled “Risk Assessment”| Category | Assessment | Evidence | Timeframe |
|---|---|---|---|
| Academic Impact | Very High | 500+ citations, influence on major labs | 2016-2025 |
| Policy Influence | High | Russell testimony to Congress, UN advisory roles | 2018-ongoing |

Core Research Framework
Section titled “Core Research Framework”The Standard Model Problem
Section titled “The Standard Model Problem”CHAI’s foundational insight critiques the “standard model” of AI development:
| Problem | Description | Risk Level | CHAI Solution |
|---|---|---|---|
| Objective Misspecification | Fixed objectives inevitably imperfect | High | Uncertain preferences |
| Goodhart’s Law | Optimizing metrics corrupts them | High | Value learning from behavior |
| Capability Amplification | More capable AI = worse misalignment | Critical | Built-in deference mechanisms |
| Off-Switch Problem | AI resists being turned off | High | Uncertainty about shutdown utility |
Human-Compatible AI Principles
Section titled “Human-Compatible AI Principles”CHAI’s alternative framework requires AI systems to:
- Maintain Uncertainty about human preferences rather than assuming fixed objectives
- Learn Continuously from human behavior, feedback, and correction
- Enable Control by allowing humans to modify or shut down systems
- Defer Appropriately when uncertain about human intentions
Key Research Contributions
