A Chinese AI startup most people outside tech circles have never heard of is about to pick a very public fight with one of the biggest names in American artificial intelligence. Moonshot AI, a Beijing-based company founded just over three years ago, is preparing to launch its Kimi K3 model with a stated goal of going head-to-head with Anthropic’s Claude Opus 4.8.
The launch window has leaked as around July 15, and the specs are genuinely eye-catching: roughly 2.5 trillion parameters, a 1-million-token context window, and a Mixture-of-Experts architecture designed for coding and agentic tasks. For context, a 1-million-token context window means the model can process the equivalent of several full-length novels in a single prompt.
What Moonshot is actually building
Moonshot AI was founded in March 2023 by Tsinghua University alumni, with CEO Yang Zhilin at the helm. The company reached a unicorn valuation of around $3 billion shortly after its founding.
Kimi K2.6, launched in April, reportedly posted leading scores on coding benchmarks against Anthropic’s Claude models. Now K3 is stepping up with a new architecture and a parameter count that dwarfs most publicly known models.
