Newcomers gain 600,000 followers in just half a month, with Douyin, Bilibili and Xiaohongshu sprinting to take the lead in the "Vibe Knowledge" track.

After the National Day holiday, a new UP master with an astonishing fan growth rate emerged on Bilibili.

Bit Neosemi, which only started submitting videos in early October, quickly became popular with more than ten hit knowledge videos in just half a month. As of October 20, the number of fans has reached 650,000, and the views of multiple videos have exceeded one million. On October 19, on the new fan growth list of Feigua Data Bilibili Edition, Bit Neosemi gained 108,000 new fans in a single day, ranking first.

Behind this "monster rookie" is Vibe Knowledge, "the content track with the fastest account creation speed and the lowest cost this year". It has exploded not only on Bilibili, but also on multiple content platforms at the same time.

The #VibeKnowledgeAwards topic on Douyin has 51,000 participants and 1.17 billion views, bringing out new creators whose single video has received millions of likes; the views of the same-named topic on Xiaohongshu have exceeded 660 million, with more than 28,000 participants, and there are many videos with more than 100,000 likes in the past week.

From information theory, entropy increase effect to Nobel Prize research results, the originally complex and difficult abstract knowledge has been packed into dynamic short films of three to five minutes. Abstract concepts are transformed into vivid and intuitive visual demonstrations. High-density information comes with smooth motion effects and a bright rhythm. After watching, you not only understand a knowledge point, but also get the pleasant feeling of watching an MV.

This boom happened right after the release of Claude Opus 5.5. On September 22, after Anthropic launched this new model, it quickly set off a trend of using natural language to drive code, produce animated short films and interactive works, which spread synchronously to China and quickly became popular among knowledge bloggers.

However, the improvement of model capabilities can only explain the sudden reduction of content thresholds. Why can such videos attract a large number of audiences in a short period of time, and why can they win the favor of Douyin, Bilibili and Xiaohongshu at the same time? In fact, behind this trend, there is a battle around new content forms and creators.

From zero-fan new accounts to millions of views, "Vibe Knowledge" has become a new content outlet

Let's first look at the top new talents who emerged in this trend.

The benchmark on Bilibili is Bit Neosemi. Among the 19 videos released since October, "Tears of the Silver Medal" has 3.61 million views, "What Exactly Is Optogenetics" has 3.06 million views, and videos such as "Razor", "Shortcut to Score Brushing" and "IceCube Neutrino" have all crossed the million view line.

The benchmark on Douyin is Electronic Homo Sapiens, which has only 11 works, with a total of 1.446 million likes. Its single video "Information Theory" has received 1.37 million likes and was selected as the "Selected Creator of September 2026". In addition to these two most eye-catching cases, accounts such as Cosmic Constant focusing on Nobel Prize interpretation, iwanau producing psychological content, and Black Hole Science Museum that has long shared astronomical popular science have also achieved significant growth recently.

Putting their videos together, you can find a similar content formula. The themes focus on hard-core knowledge concepts: entropy increase, gravitational waves, topology in the field of physics, free will and consumer psychology in psychology, Bayesian and game theory in mathematics and algorithms, as well as cutting-edge AI topics such as Scaling Law and Emergence. Coinciding with the Nobel Prize award season, timely topics such as optogenetics and neutrinos have also been quickly explored.

The expressions also have something in common: first, establish the knowledge background with the help of Shannon, Kahneman, Nobel Prizes and classic laboratories, then disassemble the originally incomprehensible concepts through continuous graphic changes, formula deduction and dynamic demonstrations. Finally, videos often extend theories to interpersonal relationships, self-cognition and daily life, connecting professional knowledge with the audience's personal experience.

Such videos not only retain the information volume of knowledge content, but also reduce the viewing burden with motion effects and music. Simply piling up knowledge tends to be abstruse, and only life insights lack freshness. Connecting theories with real experience can more easily satisfy the audience's thirst for knowledge and emotional needs at the same time.

One of the direct reasons for the popularity of such videos is that AI has greatly reduced the production cost of knowledge visualization.

This change is inseparable from the Vibe Video trend driven by Claude Opus 5.5 — the model writes codes such as HTML and JavaScript according to natural language instructions, and then turns abstract ideas into operable dynamic visual works with the help of web animation, graphic rendering and sound effect design. Whether on Github, X, or domestic communities such as Douyin and Xiaohongshu, videos produced by Opus 5.5 are becoming the new hit password.

For knowledge video creators, the change is particularly direct. AI generation tools have directly eliminated the technical barriers of knowledge visualization, reducing the supply threshold of knowledge videos to an unprecedented level: creators only need to generate pictures paragraph by paragraph through prompts and match sound effects, one person can complete the whole process from script to finished video, no real person needs to appear on the camera throughout the process, and skilled creators can iterate a complete work in one day.

In contrast, PaperClip, which was once the ceiling of domestic knowledge visualization, required 4-5 people to collaborate on a single 5-minute video, with a production cycle of 2-4 weeks; according to its public financial data in 2019, it produced 80 videos throughout the year with a total expenditure of 4.144 million yuan, and the average cost of a single video was about 51,800 yuan.

Such a cost structure is completely unbearable for the vast majority of individual knowledge creators. In the past, they could only choose between oral explanation and PPT screen recording, and the visual expression of hard-core knowledge has long been the exclusive ability of a few top teams.

The other side of low cost is that hits no longer only belong to mature accounts. Some creators have intensively analyzed 51 popular Vibe Knowledge videos on Xiaohongshu and found that half of the authors have less than 1500 fans. A game theory series account released 7 videos in 6 days, gaining 13,000 new fans, and the account explaining "Information Theory" directly rushed from hundreds of likes to 540,000 likes, gaining nearly 50,000 new fans.

These cases let more people see the opportunity to enter the market. After the result that "low-fan accounts can also get a lot of exposure with one video" has been verified repeatedly, the number of imitators has increased rapidly, and the average number of new posts on this topic per day in October has exceeded 150.

From the demand perspective, there is no shortage of audiences for knowledge videos. The daily average views of Bilibili's knowledge zone have approached 360 million, and more than 200 million users learn knowledge on Bilibili. The audience has always been there, but there were too few hard-core visualizable contents to watch in the past. Vibe Video broke the supply bottleneck, and the backlogged viewing demand was released in a concentrated manner.

Moreover, such videos themselves are designed as high-density "sense of gain" products: a complete theoretical framework is delivered in three to five minutes, the viewing experience is close to swiping a well-produced MV, and after watching, you can get a conclusion that can be retold and forwarded — on social platforms, forwarding a video about information theory is itself a social business card of "I am learning".

The extremely low supply cost hitting the huge content gap is the fundamental reason for the rapid rise of this track.

Douyin, Bilibili and Xiaohongshu all step in, starting the battle for top creators

It is worth noting that this boom is not that the content explodes first and then the platform follows the trend, but the platform has been deeply involved from the very beginning.

According to the memory of creator @iLuJinSan on Weibo, on September 29, the operation team of Douyin Technology has already actively sent private messages to invite him to participate in the "Vibe Knowledge Awards", when the topic only had millions of views; it was not until after October 2 that popular science videos with fixed BGM began to appear intensively.

This timeline shows that the platform is an indispensable behind-the-scenes promoter of the popularity of Vibe Knowledge content. As AI reduces production costs, new forms of knowledge creation have emerged, and platforms are also motivated to attract these creators as early as possible to explore their growth space in the existing content ecosystem.

For Bilibili, this is a competition to defend the basic market of the knowledge zone and amplify its own advantages.

Chen Rui, Chairman of Bilibili, once said at the financial report meeting that AI will not change the underlying logic of Bilibili, but will amplify the two major advantages of content supply and community value. The previous AI Creation Contest has accumulated more than 700 million views, 150 works have exceeded one million views, and the consumption of AI knowledge content on the platform is also growing rapidly. Behind these actions is the platform's continuous exploration of AI changing content production methods.

The rise of Vibe Knowledge brings new opportunities for Bilibili to expand the supply of knowledge content. In the past, in the popular science track, top teams took advantage of their professional production capabilities. Now, AI has greatly lowered the threshold for newbies to enter. Bit Neosemi gained 600,000 fans in half a month, which is an intuitive example: it shows more creators the communication potential of this new form.

For Bilibili, undertaking these creators also has a ready-made foundation. The platform not only has young audiences interested in knowledge content, but also a community atmosphere for discussions around knowledge, as well as creation incentives and monetization tools such as charging. The new supply brought by AI is effectively connected with Bilibili's original content ecosystem.

For Douyin, Vibe Knowledge content is a bridgehead that must be won when it advances in depth into the knowledge track.

In the past two years, Douyin has been using Douyin Selection to make up for the shortcomings of in-depth content. This product meets the aggregation demand of high-quality medium and long videos in the Douyin ecosystem. From the perspective of user scale, this layout has achieved initial results. According to QuestMobile data, in December 2025, the monthly active user scale of Douyin Selection App reached 42.241 million, a year-on-year increase of 184.5%, and the monthly average usage time per person reached 10.4 hours.

At the Creator Conference in September this year, Douyin continued to take high-quality in-depth content as the key direction, and the annual views of technology content on the platform have exceeded 1.4 trillion times. From the Vibe Coding Awards to the Vibe Knowledge Awards, Douyin's intention is consistent: its basic market of entertainment content has peaked, and knowledge consumption is the most certain increment in terms of user duration and content tonality.

The new form of Vibe Knowledge videos, which are generated by AI, are naturally friendly to vertical screens, and fit the recommendation stream in three to five minutes, just makes up for Douyin's shortcomings of "high supply cost and few professional authors" in knowledge content. If the standard of this generation of knowledge videos is finalized on Douyin, Douyin will get the key ticket for transformation from an entertainment platform to a knowledge platform.

Xiaohongshu's undertaking of this boom is closely related to its existing Vibe Coding and AI tool community.

Since the beginning of this year, Vibe Coding and AI tool learning have become active content on Xiaohongshu. 40,000 to 50,000 Vibe Coding works are published on the platform every month, with more than 1.6 million related discussions. The creators of Vibe Knowledge highly overlap with the first batch of users who studied AI programming and AI tools.

It is worth noting that the Vibe Knowledge content on Xiaohongshu has shown the possibility of combining with small tools and interactive games.

Under the Vibe Knowledge Awards topic, Mo Dian Lab released a popular science video "Why the results are so different when everyone claps the same way", which received more than 40,000 likes in 3 days. Taking advantage of the popularity of the video, the team also hung a mini-game called "Who Will Clap Along" in the comment area, allowing users to personally participate in the experiment and experience the knowledge points in the video.

This means that the value of knowledge videos can go beyond viewing itself: videos are responsible for raising questions and clarifying principles, while mini-games allow users to verify them in person. A connection has been formed between content, tools and interactive experience, which also provides new extension space for Vibe Knowledge content.

The core of this positioning battle is the competition for the first batch of top creators. In the early stage of the AIGC content boom, whoever first creates benchmark accounts and establishes an industry-recognized creation standard can attract more creators and form the content moat of the platform.

Next, platforms need to make these creators find stable audiences through recommendation, operation and product design. Compared with how many fans a certain blogger has gained in the short term, whether it can continuously attract new authors to join and make them willing to update on the platform can better reflect the value of this round of competition.

Content homogenization is accelerating, how to turn short-term traffic into long-term value?

However, this may also be one of the content outlets with the shortest window period.
