hebrew-gpt_neo-tiny

Hebrew text generation model based on EleutherAI's gpt-neo. Each was trained on a TPUv3-8 which was made avilable to me via the TPU Research Cloud Program.

Datasets

1. An assortment of various Hebrew corpuses - I have made it available here

2. oscar / unshuffled_deduplicated_he - Homepage | Dataset Permalink

The Open Super-large Crawled ALMAnaCH coRpus is a huge multilingual corpus obtained by language classification and filtering of the Common Crawl corpus using the goclassy architecture.
