MHRC-Bench (Preceding Context) - Chisel: leaderboard
Repository-level hardware code completion (MHRC-Bench, Zou et al., National University of Singapore, 2026) in Chisel (a hardware construction language embedded in Scala): from a 2,048-token prompt holding only the code before the target in a held-out repository, the model writes the missing syntactically complete code unit of one or more lines, without retrieval. Exact match in percent after comments and whitespace are stripped; higher is better.
Metric: Exact match (%; repository-level completion of syntactically complete Chisel code units given the preceding code only in a 2,048-token prompt, no retrieval). Source: arxiv.org. Saturation forecast: Around May 2028. 4 models tracked.
