Introduction
If you are a physicist, you have a special skill: glancing at an extremely complex formula and immediately judging whether it matches reality, or where its physical significance lies. This "physical intuition" usually takes decades to accumulate.
Now, researchers are trying to transfer this intuition to AI. The latest research, PRL-Bench (2026), builds an unprecedented "intuition mine": based on 100 major papers from the top journal *Physical Review Letters* (PRL) over the past two years, it sets an extreme challenge for AI.

#### 1. The Deep Waters of Physics: Long-Range Reasoning and Formula Intuition
Current AI models can solve math problems, but when facing advanced theoretical physics, they often exhibit a kind of "logical gap."
- Long-range reasoning: A physics proof may span over a dozen pages, requiring constant switching between physical pictures. AI tends to lose focus during these complex "thought experiments."
- Formula intuition: A real physicist can discover a new conserved quantity from a tiny change in a single symbol. AI often treats formulas as rigid character combinations, lacking a deep understanding of "symmetry" and "causality."
- Long-range formula derivation: Requires the AI to fill in missing derivation steps, with each step accompanied by a clear explanation of its physical meaning.
- Experimental data logic reconstruction: Gives the AI a pile of messy quantum observation data and tests whether it can independently derive the paper's core findings.
- Intuition conflict tests: Specially designed counterintuitive physics scenarios (e.g., topological phase transitions) to see whether the AI falls into traps of common sense.
- Clear weaknesses: AI performs reasonably well on local logical derivations, but remains far from top human minds in terms of global perspective and judgments of "physical aesthetics."
- Huge potential: This kind of high-difficulty benchmark is forcing AI to evolve toward deeper physical representations rather than simple probabilistic prediction.
#### 2. PRL-Bench: A Sharpening Stone for AI Physicists
PRL-Bench selects, from frontier fields such as condensed matter physics and high-energy physics, the tasks that most test "physical insight":
#### 3. Results: The Shock of Scores Below 50
Experimental results show that even the current strongest scientific models generally score below 50% on PRL-Bench.
#### Editorial Commentary
Physics is the crown of human intelligence.
The arrival of PRL-Bench marks AI scientific training entering a stage of "pure thinking." We are no longer just giving AI manuals to read — we are asking it to study how the most powerful minds that change the world think. Quantifying and conquering "physical intuition" will directly determine whether future AI can independently derive its own "E=mc²."
If you could ask a future AI physicist one question about the universe, what would you most want it to work out for you?
