First-of-their-kind models for the long tail.

We've built the first language models and translation systems for languages that had none, through new work on data collection, multilingual architectures, and controlled generation.

Models

Machine translation and language models for the long tail of languages and domains. From our current work:

OkaMT-1.3B

Machine Translation Model

We introduced machine translation for four languages not currently supported by commercial systems. Together with English, OkaMT-1.3B translates between all five, 20 directional pairs in total. Oshikwanyama ⟷ English is our strongest.

OkaLM

Kwanyama Language Models

OkaLM is the first family of publicly available large language models for Kwanyama. Available in three sizes (1B, 3B, 8B parameters) to suit different use cases, from lightweight applications to more capable generation.

Who we are

Founded in 2021, Okalai held its first AI school in 2022 and grew from those schools into a research program building first-of-their-kind models for the long tail of languages and domains. We have trained the first LLMs and machine-translation systems for several languages that previously had none.

Okalai AI was founded by Ndapa Nakashole, who serves as Chief Scientist. Ndapa is an Associate Professor of Computer Science at the University of California, San Diego (UCSD). Her research focuses on Natural Language Processing (NLP), and Artificial Intelligence (AI) more broadly.
