IFParse is a benchmark for structured extraction from real developer logs: can a model turn a raw, unstructured log line into JSON that satisfies a fixed schema, with no code fence, no commentary, and no type errors.

Each prompt gives the model a single raw log line, either an Apache access log record… See the full description on the dataset page:
