Researchers have developed Khmer PFGen-Bench, a novel benchmark designed to evaluate open-ended text generation in Khmer, a low-resource language. Unlike many existing benchmarks that rely on LLM judges, this new benchmark uses a judge-free approach adapted from a Japanese benchmark. It employs keyword rules and n-gram statistics, utilizing references generated by various post-trained models to ensure validity and variety. The study found that mixing different model families increases reference diversity and that the benchmark's rankings are stable and align with human ratings, offering a template for similar benchmarks in other low-resource languages.
