Preferred Networks opens PLaMo 3 Translate weights

Preferred Networks is making available the same translation-specialized model that already runs its PLaMo translation service, rather than a separate research release. The open-weights approach means the model weights needed to run it on each user's device are published, so developers can integrate it into their own applications.

The four sizes — 0.8B, 2B, 8B, and 31B — give users a trade-off between translation quality, speed, processing volume, and the hardware they intend to use. Once embedded, the model can translate 53 languages including Japanese and English on smartphones and laptops without a network connection, according to the announcement.

The licensing terms set a clear threshold: companies with annual revenue under ¥1 billion and individuals can use the model free for commercial or non-commercial purposes under the PLaMo Community License, including on edge devices such as smartphones, laptops, and internal servers. This suggests the release is aimed at broadening access for smaller developers and individual users, though the body does not state terms for larger companies.
