2025/05/23: Published a blog post about Kanana 1.5 models and released 🤗HF model weights.2025/02/27: Released Technical Report and 🤗HF model weights.2025/01/10: Published a blog post about the development of Kanana Nano model.2024/11/14: Published blog posts (pre-training, post-training) about the development of Kanana models.2024/11/06: Published a presentation video about the development of the Kanana models.Kanana 1.5, a newly introduced version of the Kanana model family, presents substantial enhancements in coding, mathematics, and function calling capabilities over the previous version, enabling broader application to more complex real-world problems. This new version now can handle up to 32K tokens length natively and up to 128K tokens using YaRN, allowing the model to maintain coherence when handling extensive documents or engaging in extended conversations. Furthermore, Kanana 1.5 delivers more natural and accurate conversations through a refined post-training process.
