I tried to test China’s newest ChatGPT rival but couldn’t get in — and it exposed the next big problem facing the major AI players
China’s newest AI model has a capacity problem — and that tells us something about the whole AI race

China’s latest ChatGPT rival, Kimi, is now available for download on the Apple App Store, so I downloaded it on my iPhone, intending to test it against ChatGPT, Claude and Gemini. I had the prompts ready; I had the comparison planned. Then Kimi presented me with a very modern problem that I wasn’t expecting: too many people were already trying to talk to it.
This is not just app-launch inconvenience. It captures one of the biggest problems in AI right now: being clever is one thing, but the best models are only useful if companies have enough servers and GPUs to allow people to actually use them.
In our recent Kimi review we said: "Kimi delivers impressive performance for coding, document analysis, and multi-step agentic tasks, especially considering its price point." Kimi may be positioned as a serious open-weight rival to US models, but if the first ordinary-user experience is that they're stuck queuing at the door, how useful is it really?

What is Kimi?
Do you remember back in 2025, when DeepSeek-R1 was released and the internet went wild for Chinese AI models? It was a game-changing moment, because it immediately became obvious that we weren’t beholden to the Silicon Valley giants like OpenAI, Google and Anthropic for AI. China could create AI models too — and, it turned out, they were a lot cheaper to run, and almost as good.
While DeepSeek was arguably the first Chinese AI model to really break through into the mainstream, Kimi is the latest. Its story is slightly different, because it’s a giant open-weight model that’s not just cheap and technically impressive, but directly useful for coding, spreadsheets, knowledge work, and long-context tasks with agent-style workflows.
Open weight means the finished AI model is available for others to download and run, rather than only being accessible through the company’s own app or website. That is not the same as being fully open source, of course. Open source would imply a much more complete release of the code, training process, data details and license freedoms needed to understand, rebuild and modify the model from the ground up.
The data squeeze
I’d love to be able to open my phone, try a serious Chinese AI model, and get something genuinely competitive in minutes. But without the capacity to serve the millions of people who pile onto a hyped new AI model, raw intelligence only gets you so far.
