PFN is putting a translation-specialized model in an open-weight format at sizes that run on a phone, which moves on-device translation from a cloud service feature to something a user can download and run offline.
Key Facts

- The weights are published on Hugging Face and can run locally without sending text to an external cloud service.
The release covers four sizes from 800 million to 31 billion parameters, downloadable and runnable on local hardware without a cloud service. PFN says the smallest model outperformed existing translation LLMs with more than 30 times its parameter count in its own Japanese-English evaluation. The model supports 53 languages and allows commercial use if conditions are met.
The weights are on Hugging Face under the pfnet organization, in 0.8B, 2B, 8B and 31B sizes, so the choice comes down to the hardware in front of you rather than a subscription tier. The 0.8B model is aimed at phones and other limited devices. PLaMo 3 Translate takes surrounding sentences as context during translation and accepts a glossary for fixing proper nouns and technical terms. For Japanese output it can produce either the polite desu/masu style or the plain da/dearu style. Commercial use is allowed if conditions are met.
