[2024.05.24] We release updated version InternLM2-Math-Plus with 4 sizes and state-of-the-art performances including 1.8B, 7B, 20B, and 8x22B. We improve informal math reasoning performance (chain-of-thought and code-intepreter) and formal math reasoning performance (LEAN 4 translation and LEAN 4 theorem proving) significantly.
[2024.02.10] We add tech reports and citation reference.
[2024.01.31] We add MiniF2F results with evaluation codes!
[2024.01.29] We add checkpoints from ModelScope. Update results about majority voting and Code Intepreter. Tech report is on the way!
[2024.01.26] We add checkpoints from OpenXLab, which ease Chinese users to download!
