CelloAI-Doc-Bench - Differential Similarity: leaderboard
Metric: Mean embedding cosine similarity (-1 to 1, times 100) between the descriptions the model writes for the same parameter in 18 caller-callee function pairs of FastCaloSim's CUDA port (documentation coherence); Doxygen-style comments generated by the model for scientific/HPC C++ and CUDA functions (FastCaloSim and ATLAS Athena code), temperature 0.1, mean of 10 runs; higher is better. Source: arxiv.org. Saturation forecast: Estimated already saturated. 5 models tracked.
