China's Moonshot AI reportedly used Nvidia Blackwell chips for training Kimi K3
2 months ago
- Moonshot AI reportedly used Nvidia Blackwell chips to train its Kimi K3 model, bypassing U.S. export and Chinese import controls.
- The company circumvented restrictions by utilizing two Chinese firms with Blackwell chips in their datacenters and linking multiple servers across facilities.
- A researcher noted that Kimi K3 has sparked a new AI arms race in China, as homegrown chips lag behind Nvidia's offerings.
- For inference, Moonshot relies on Nvidia's HGX H20 chips, but faces capacity shortages and has a waiting list for Kimi K3 subscriptions.
- The White House claims Moonshot accessed advanced GB300 servers, exploiting a rental loophole that may be closed by the proposed Remote Access Security Act.
- The U.S. Department of Commerce is investigating Chinese firms' access to advanced chips amid ongoing tensions in the AI supremacy race.

- Moonshot AI released the weights for their 2.8 trillion parameter Kimi K3 model, which is 1.56TB on Hugging Face.
- The K3 license, unlike the modified MIT license used for K2, requires a separate agreement for large 'Model as a Service' businesses with over $20 million annual revenue.
- Kimi consistently refers to K3 as 'open weight' rather than 'open source' in their materials.
- OpenRouter offers K3 from 7 providers at the same pricing as Moonshot AI: $3/million input and $15/million output.

- Moonshot AI's Kimi-K3 is the next generation open frontier model, scheduled for release on July 27, 2026.
- It is the world's first open 3T-class model, focusing on long-horizon coding, knowledge work, and reasoning.
- Key features include a new architecture with Kimi Delta Attention and Attention Residuals, native agentic capabilities (tool calling, browsing, multi-step planning), and an extended context window for repository-scale code understanding.
- The model will have open weights released on the same page, and users can sign up for a single notification email when weights become public.
- Over 1,820 users are already waiting for the release.
Top White House official escalating the fight over Moonshot AI's Kimi K3 model

- A White House official accused Moonshot AI of stealing from Anthropic by distilling the Fable model for its K3 model.
- Moonshot AI allegedly used a sophisticated internal platform to conduct large-scale distillation while evading detection.
- Kimi K3 is a leading open-source AI model, performing at or above the level of models from Anthropic and OpenAI, but will be released freely.
- The White House stressed that legitimate distillation is acceptable, but covert industrial distillation to steal technology is not.
- Treasury Secretary suggested possible sanctions against Chinese companies if improper distillation is proven.
- This incident marks a rare alignment between the Trump administration and Anthropic, following previous tensions.
- Anthropic's head of public policy thanked the official and called illicit distillation a national security risk.
Kimi K3, and what we can still learn from the pelican benchmark
2 months ago
- Moonshot AI released Kimi K3, a 2.8 trillion parameter model described as their most capable to date.
- K3 is currently available via website and API, with an open weight release promised by July 27, 2026.
- Self-reported benchmarks show K3 outperforms Claude Opus 4.8 max and GPT-5.5 high but loses to Claude Fable 5 and GPT-5.6 Sol.
- Artificial Analysis reports K3's Elo is 1547 on long-horizon knowledge work, with cost per task similar to GPT-5.6 Sol.
- Pricing is $3/million input tokens and $15/million output tokens, making it the most expensive Chinese AI lab model.
- The author uses a 'pelican riding a bicycle' SVG generation test to explore model characteristics.
- K3's test revealed high reasoning token usage (13,241 tokens), costing 25 cents, and a potential hidden system prompt.
- The pelican benchmark is limited, especially regarding agentic tool calling, and shouldn't be used to compare models.
- Despite limitations, the test serves as a forcing function to try models and reveals details like cost and SVG capability.
