MiniCPM5 2B Midtrain

MiniCPM5 2B Midtrain is the second model in the MiniCPM5 series, a dense 2B Transformer from OpenBMB built for on-device, local deployment, and resource-constrained scenarios. It scales up the same training recipe used for MiniCPM5-1B and is released under the apache-2.0 license. The model card describes it as reaching 2B-class open-source SOTA within its comparison set and remaining competitive with 4B-class models overall, with reported advantages over comparable-size models in coding, mathematics, long-context understanding, tool use, and agentic tasks. Languages listed are English and Chinese, and the model is associated with the transformers library and text-generation pipeline. Training data includes openbmb Ultra-FineWeb, UltraX-Preview, Ultra-FineWeb-L3, UltraData-Math, UltraData-Code, UltraData-SFT-2605, UltraData-SFT-Agent-2609, and UltraData-RL-2609.

What do these scores mean?

Two ways to compare models. Neither score measures answer quality, benchmark performance, or whether a model fits your machine.

Freshness · release age

A new release starts at 100. The score halves every 180 days: 100 × 2^(−age in days / 180). When the release date is unavailable, a repository date is a fallback—not proof of when the model was released. Missing dates stay unscored.

Popularity · adoption

Downloads over the past 30 days carry 80% of the score; lifetime likes carry 20%. Both use a logarithmic scale, capped at 10 million downloads and 100,000 likes. If likes are unavailable, downloads carry all the weight. Missing download statistics stay unscored.

round(80 × min(1, log10(1 + downloads) / 7) + 20 × min(1, log10(1 + likes) / 5))
