It releases the <strong>Sarashina<\/strong> language models on its <a href=\"https:\/\/huggingface.co\/sbintuitions\">sbintuitions organization on Hugging Face<\/a>.<\/p>\n<h2>What It Releases<\/h2>\n<ul>\n<li><strong>Sarashina2<\/strong> (2024): 7B, 13B and 70B, plus the 8x70B MoE. The model cards describe them as &#8220;language models trained by SB Intuitions&#8221;; the company trains large Japanese-centered models in-house.<\/li>\n<li><strong>Sarashina2.2<\/strong> (March 2025): small 0.5B, 1B and 3B models and their instruction-tuned versions (instruct-v0.1).<\/li>\n<li><strong>Speech models<\/strong>: in 2026 it released sarashina2.2-tts (April), a Japanese-centric text-to-speech system built on a large language model; the speech recognition model hikari-medium (May); and kana-whisper (May), a Whisper large-v3-turbo fine-tune that transcribes Japanese speech directly into katakana.<\/li>\n<li>There is also DuplexCascade (March 2026), which requires accepting its license to access.<\/li>\n<\/ul>\n<h2>Licenses<\/h2>\n<p>Most Sarashina2 and Sarashina2.2 models and the speech recognition models are <strong>MIT<\/strong>, broadly usable including commercially. However, sarashina2.1-1b and sarashina2-8x70b use a custom license (<code>other<\/code>), and sarashina2.2-tts has no license field. Read each model&#8217;s license text before use. This summary is not legal advice.<\/p>\n<h2>Running Them Locally<\/h2>\n<ul>\n<li><strong>There are no official GGUF builds<\/strong> (as of 2026-09-26). For llama.cpp and Ollama, look for third-party conversions.<\/li>\n<li><strong>On consumer hardware, the Sarashina2.2 0.5B to 3B models are easy to handle.<\/strong> The 70B and 8x70B need data-center GPUs even when quantized.<\/li>\n<\/ul>\n<p><em>Sources: <a href=\"https:\/\/www.sbintuitions.co.jp\/company\/\">the SB Intuitions company profile<\/a>; model cards of <a href=\"https:\/\/huggingface.co\/sbintuitions\/sarashina2.2-3b-instruct-v0.1\">sbintuitions\/sarashina2.2-3b-instruct-v0.1<\/a> and <a href=\"https:\/\/huggingface.co\/sbintuitions\/sarashina2-70b\">sbintuitions\/sarashina2-70b<\/a>; the model list of the sbintuitions organization on Hugging Face (all as of 2026-09-26).<\/em><\/p>\n<h2>Our Coverage and Data<\/h2>\n<p>Local Model Watch has not published an article on SB Intuitions (SoftBank)&#8217;s models yet.
