Enabling Language-specific Reasoning in Multilingual Models with Reinforcement Learning
- 24 July 2026
We introduce the Poro 2 Long family of models, a follow-up to the Poro 2 family that demonstrated exceptional performance in Finnish and English instruction-following and conversational tasks. This model family demonstrates our progress in developing models capable of reasoning in the same language as the user. A prerequisite for an effective reasoning model is the ability to process longer sequences beyond the sequence lengths used in pretraining; therefore, the Poro 2 Long models feature a context window of 128k tokens.
