What is BettaFish?

BettaFish (“Micro Opinion” in Chinese) is a program developed by a number ofintelligent body(Multi-Agent) Collaboration-Driven Open Source AIPublic Opinion AnalysisThe tool is designed to break the information cocoon, restore real public opinion and predict trends. Its core innovation lies in a “forum-style” collaboration mechanism that mimics human team discussions, enabling multiple AI intelligences to work together to improve the depth and accuracy of analysis. Launched as a graduation project by developer Guo Hangjiang (screen name BaiFu) in the summer of 2025, the project quickly became a hit on GitHub, accumulating more than 24K starred labels and topping the global trend list.

Development team and background

• Core DevelopersBaiFu is a senior student at the University of Science and Technology of China (USTC), and a representative of “super individuals” in the field of AI.
• technology model: Adopting the “Vibe Coding” development model, combined with theAI Programming Tools(e.g., Claude Code) with human decision-making to achieve fast time-to-market from idea to product.
• Investment support: In March 2026, Chen Tianqiao, founder of Shanda Group, invested 30 million yuan in its advanced version of the product, MiroFish, for technology incubation and commercialization exploration.
