A joint paper by Google, UCLA, and CMU introduces GenXR-Bench, revealing that mainstream LLMs struggle to build virtual reality applications. While Claude Opus 5 leads with a 50.9% score, no model exceeds 29.2% on SDK feature tasks, primarily due to coordinate-frame errors and startup race conditions.

New Benchmark Reveals AI Coding Tools Fail in XR Development
- GenXR-Bench features 112 expert-written tasks testing XR app building via simulated hand and room inputs.
- 64.4% of failures stem from coordinate-frame errors in 3D space, while 44.9% involve startup race conditions.
- Traditional unit tests miss runtime spatial logic errors; validation with simulated inputs is recommended.
