Four Chinese AI startups to watch beyond DeepSeek

4 days ago 53

The meteoric rise of DeepSeek—the Chinese AI startup now challenging global giants—has stunned observers and put the spotlight on China’s AI sector. Since ChatGPT’s debut in 2022, the country’s tech ecosystem has been in relentless pursuit of homegrown alternatives, giving rise to a wave of startups and billion-dollar bets. 

Today, the race is dominated by tech titans like Alibaba and ByteDance, alongside well-funded rivals backed by heavyweight investors. But two years into China’s generative AI boom we are seeing a shift: Smaller innovators have to carve out their own niches or risk missing out. What began as a sprint has become a high-stakes marathon—China’s AI ambitions have never been higher.

An elite group of companies known as the “Six Tigers”—Stepfun, Zhipu, Minimax, Moonshot, 01.AI, and Baichuan—are generally considered to be at the forefront of China’s AI sector. But alongside them, research-focused firms like DeepSeek and ModelBest continue to grow in influence. Some, such as Minimax and Moonshot, are giving up on costly foundational model training to hone in on building consumer-facing applications on top of others’ models. Others, like Stepfun and Infinigence AI, are doubling down on research, driven in part by US semiconductor restrictions.

We have identified these four Chinese AI companies as the ones to watch.

Stepfun

Founded in April 2023 by former Microsoft senior vice president Jiang Daxin, Stepfun emerged relatively late onto the AI startup scene, but it has quickly become a contender thanks to its portfolio of foundational models. It is also committed to building artificial general intelligence (AGI), a mission a lot of Chinese startups have given up on.

With backing from investors like Tencent and funding from Shanghai’s government, the firm released 11 foundational AI models last year—spanning language, visual, video, audio, and multimodal systems. Its biggest language model so far, Step-2, has over 1 trillion parameters (GPT-4 has about 1.8 trillion). It is currently ranked behind only ChatGPT, DeepSeek, Claude, and Gemini’s models on LiveBench, a third-party benchmark site that evaluates the capabilities of large language models.

Stepfun’s multimodal model, Step-1V, is also highly ranked for its ability to understand visual inputs on C...
