Last week, a Chinese-made large language model called Kimi K3, developed by Beijing-based firm Moonshot AI, burst onto the scene.
The open-weight model impressed with early benchmark results, trading blows with some of the most advanced closed-weight ones being developed by the likes of OpenAI and Anthropic — and at a fraction of the cost.
Much like Chinese competitor DeepSeek’s AI model upending Silicon Valley in early 2025, Kimi-K3 sent shockwaves across the industry. A major sell-off roiled the tech-heavy Nasdaq, with the S&P 500 slipping after the unveiling.
For top closed-weight AI labs, it was the perfect storm. Executives are already balking at rapidly rising costs and desperately looking for cheaper alternatives. Kimi K3 may end up luring them in, making it even harder for the likes of OpenAI and Anthropic to attract new customers — right as they need to cover at least some of their exorbitant costs.
