-**Stockmark-2-100B-Instruct-beta** is a 100B parameter large language model specialized in Japanese. It was built from scratch through pre-training with 1.5T tokens and post-training.
+**Stockmark-2-100B-Instruct-beta** is a 100B parameter large language model built from scratch, which is particulary specialized in Japanese. The model was pretrained on approximately 1.5 trillion tokens of data (60% English, 30% Japanese, 10% Code). After pretraining, the model underwent post-training using synthetic data to enhance its instruction-following abilities. The synthetic data was generated using Qwen2.5-32B-Instruct.

+As a beta release, Stockmark-2-100b-Instruct-beta is still undergoing improvements and evaluations. Feedback and insights from users will help refine future versions.
