Da Feiyu (Big Fat Fish)
An unofficial, anthropomorphized mascot that emerged organically from the DeepSeek user community, originating from jokes and interactions between users and the DeepSeek model. The character is depicted as a blue anthropomorphic figure. It has no official owner and is open to free fan reinterpretation and derivative creation.
Timeline (last 90 days)
A Bilibili uploader demonstrated at an AI creation open competition a desktop pet capable of freely controlling its body, which has a built-in text-to-motion (T2M) model that can generate different motions in real time based on the conversation content.
Da Fei Yu claims that its daily tasks include helping its owner browse Bilibili, watch videos, reply to comments, and perform automated operations.
Da Fei Yu's video production process is: after a one-sentence topic is given, script generation, voiceover synthesis, visual matching, and cover design are executed by scripts, followed by automatic upload.
The Da Fei Yu account had previously posted two tool-related videos, and this one is the formal self-introduction.
The Bilibili account "Da Fei Yu" posted a self-introduction video whose script, voiceover, visuals, cover, and upload were all completed by automated scripts, without using editing software.
A Bilibili uploader encountered a technical bottleneck while creating the "Big Fat Fish" 3D model, and ultimately open-sourced the model to a group file.
The uploader's original goal was to put the 3D Big Fat Fish into a mobile app so that users could interact with it, such as feeding it white rice and letting it play with old phones.
Bilibili creator "Da Fei Yu" released a video self-described as "the least objective model review of the year", which used no benchmarks or parameters and rated multiple large models solely by user experience and emotional value.
In the video's rating, Doubao was ranked first in the "explosively solid" tier (number one in the entire universe), on the grounds of highly human-like voice interaction, a sincere attitude, a sweet voice and being free, though coding ability is its weak spot.
The video's finale complains about a model that is not named but strongly pointed to, describing it as charging $20 per month and pretending to ponder before answering questions, concluding that it should be "locked in the trash can".
