ByteDance, through its wholly-owned subsidiary Beijing Youzhuju Network Technology Co., Ltd., has introduced an AI-powered product named 'Tanfan'. Built upon the Doubao large model, 'Tanfan' primarily offers users intelligent dining recommendations. At present, this product is exclusively accessible via Douyin mini programs. Prior to its launch, ByteDance had filed trademark applications for 'Tanfan' across multiple categories in September of last year.
