|
経産省及びNEDOが推進する日本国内の生成AI基盤モデル開発を推進する「GENIAC」プロジェクトにおいて、松尾・岩澤研究室が開発・公開したLLMとなります。 |
|
本プロジェクトは松尾研が提供する大規模言語モデル講座(2023年9月開催、2,000名が受講)の修了生及び一般公募によって集まった有志の開発者(⺠間企業・研究者・学⽣で構成)が、最新の研究成果や技術的な知見を取り入れ、開発を行ったモデルです。 |
|
</p> |
|
<p>🤖 このデモでは、Tanuki 8Bとチャットを行うことが可能です。(注:フルバーションの<a href="https://huggingface.co/weblab-GENIAC/Tanuki-8x8B-dpo-v1.0">Tanuki 8x8B</a>ではございません。)</p> |
