A Beijing-based artificial intelligence start-up, Moonshot AI, has launched a new open-source model named Kimi K2 Thinking, which it claims outpaces leading closed-source systems from the United States in reasoning, coding and “agent” tasks.
The model is presented as a “thinking agent” capable of executing multi-step reasoning and interacting with software tools, such as search engines, code execution environments and web APIs. Moonshot says it trained the model for approximately US$4.6 million – a cost that analysts note is dramatically lower than those incurred by proprietary rivals – and it has already become the most-used model by developers on the platform Hugging Face.
In benchmark tests published by independent indexers, Kimi K2 Thinking reportedly exceeded the performance of GPT‑5 and Claude Sonnet 4.5 — among the world’s most advanced models — in metrics assessing reasoning depth, coding fluency and autonomous tool use. Some analysts say the model may represent another “DeepSeek moment,” referencing a previous Chinese model launch that disrupted expectations of U.S. AI leadership.
The release is being viewed as a strategic signal in the global AI race, particularly given its open-source nature, comparatively low cost and competitive results. Moonshot’s architecture is reported to feature around 1 trillion parameters in a mixture-of-experts design, supports long-context windows and enables dynamic tool orchestration, according to documentation posted on Hugging Face and company blogs.
Industry observers caution that while benchmark results and open access are notable, real-world adoption, regulatory oversight, safety guard-rails and long-term robustness remain in early stages. However, the model’s emergence intensifies pressure on Western vendors, as it highlights how low-cost, high-capability open-weight models are gaining traction rapidly within the Chinese ecosystem and potentially beyond.
With Kimi K2 Thinking now publicly available under an open licence, attention will focus on how quickly developers integrate it, how it scales commercially and how rival labs respond. The model marks not simply a technical milestone but a shift in the competitive landscape — one in which open-source reasoning agents built in China are asserting influence on the global stage.








The autumn auction staged by Stack’s Bowers & Ponterio in Hong Kong spanned eight days and encompassed approximately 8,500 lots of world coins, Chinese rarities and paper currency. The sale realised in excess of US$18 million, underlining the firm’s pre-eminence in the numismatic market and demonstrating growth in Asian demand.
The opening session, dubbed “Rarities Night”, featured 233 premier lots focused on Chinese treasures and achieved US$6.206 million in total. A gold “Flying Dragon” dollar pattern (Lot 40161) led the session, achieving a hammer price of US$504,000. Other notably strong performers included a Kiangnan 7 mace 2 candareen gold coin graded PCGS MS-62 (Lot 4005) which realised US$240,000, and a gold presentation “Pavilion” dollar (Lot 40173) also selling for US$240,000.
Across subsequent sessions, additional highlights included a Foochow Arsenal silver award medal (Lot 40229) that realised US$140,000, and a gold 10-tael ingot dating circa 1750 (Lot 41039) which fetched US$78,000. From the Philippines, an 1828 overstrike on a Peru-mint 8 reales (Lot 43496) achieved US$114,000. Paper-money sales likewise thrived: a People’s Bank of China 10 yuan note (Lot 31075) realised US$114,000 and a Hong Kong Chartered Bank of India, Australia & China US$5 note (Lot 31101) sold for US$55,000.
Throughout the auction, Chinese rarities—both in coin and paper form—anchored the market, reflecting strong regional collector interest and international investor participation. The realisation of multiple six-figure lots and a total auction result above US$18 million further reinforce the company’s leading position and the robustness of the Asian numismatic segment.
As consignors and bidders now assess the results, the performance offers insight into price levels for Chinese rarities and paper money entering market channels in 2025. With global collectors increasingly active in Asia, the Hong Kong auction sets a benchmark for forthcoming world-currency and numismatic sales in the region.
