Researchers have introduced VeriCodeBench, a new benchmark designed to evaluate large language models' ability to generate code that is both functional and formally verifiable. Unlike previous benchmarks, VeriCodeBench requires LLMs to generate their own specifications and code without external guidance, covering practical software development tasks in C, Java, Rust, and Python. The study also presents CodeNova, a system that improves LLM performance by making requirements explicit and using verifier feedback for code repairs. Experiments showed that while self-generated specifications are a bottleneck, CodeNova significantly boosted performance, with Claude Sonnet-5 achieving the best results under this self-spec protocol.
