MiniCPM5 2B Base

MiniCPM5 2B Base is a dense 2B Transformer text-generation model from the MiniCPM5 series, released under the Apache-2.0 license by openbmb. It is positioned for on-device, local deployment, and resource-constrained scenarios, and its model card describes it as reaching 2B-class open-source SOTA within its stated comparison set. The model supports English and Chinese, uses the transformers library, and is associated with long-context, tool-calling, on-device, and edge-ai tags. It was trained on datasets including Ultra-FineWeb, UltraX-Preview, UltraData-Math, UltraData-Code, and several UltraData SFT/RL datasets.

Freshness 83 out of 100. Repository age: 49 days old, Aug 27, 2026. Measures age, not quality.

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))

Tradeoffs

  • The supplied facts do not specify detailed context length limits.
  • No specific hardware requirements are provided.
  • No information is given about supported inference frameworks beyond the transformers library.
  • Performance outside the stated comparison set is not described.
  • No testing or benchmark results are provided beyond the claimed 2B-class open-source SOTA statement.
