PROBE (Code Generation) - C++: leaderboard
The C++ track of PROBE (UNC Charlotte and University of Coimbra, Empirical Software Engineering 2026): models write complete C++ programs for 1,651 English-language Project CodeNet problems with extended unit tests, five samples per problem under the baseline prompt. The score is the passed outcome rate, the share of unit-test executions that pass, in percent; higher is better.
Metric: Passed outcome rate (%): share of unit-test executions that pass, averaged over the unit tests of each problem, 5 generated samples per problem and the 1,651 filtered Project CodeNet problems, for complete C++ programs under the baseline prompt; higher is better. Source: arxiv.org. Saturation forecast: Around February 2027. 6 models tracked.
