Note Over 10k problems scrapped from the CodeForces platform (almost all the available problems). Includes: - Text rendering of latex equations (using Qwen-VL) - Problem metadata (tags, difficulty, etc) - Editorials when available - Special model-generated checkers to validate problems with multiple correct answers - Model-generated additional test cases for problems where not all test cases are public

Note CodeForces-CoTs is a large-scale dataset for training reasoning models on competitive programming tasks. It consists of 10k CodeForces problems with up to five reasoning traces generated by DeepSeek R1
