What is Poro 34B?
Poro 34B is a 34-billion-parameter bilingual Finnish-English language model developed by SiloGen (Silo AI) and the University of Turku TurkuNLP group. Released in 2023 as part of Europe's High Performance Language Technologies (HPLT) initiative, Poro is one of the best open Finnish LLMs ever created.
It's released under Apache 2.0, free for any commercial use, with multiple checkpoints available throughout training for transparency.
