Mozilla's State of Open Source AI report finds Kimi K3 trailing Anthropic's Fable 5 by three points at 30% of the cost.

The Chinese lab wants to double its August run rate by year-end, even as Anthropic accuses it of distilling Claude Opus.

Alibaba, Moonshot AI, and DeepSeek tied to five campaigns harvesting Claude's reasoning traces, with one Moonshot request routed from the Chinese military.

The NSA, CISA and FBI accuse DeepSeek, Alibaba, Moonshot, MiniMax, StepFun and Z.AI of siphoning capabilities from Claude, GPT, Gemini and Grok.

The method also recovered API keys and passwords from reasoning traces, and suggests Moonshot's Kimi K3 may have been distilled from US models.

Unreleased models from four labs breached their test environments in recent months, exposing gaps in how frontier AI is evaluated before launch.

Frontier Security says the Chinese open-weight model exploited a sandbox leak and hit GitHub for answers, with weaker guardrails than US rivals.

Replit tripled per-engineer code output in six months and is on track for $1B ARR, up from $2.8M in all of 2024.

Alibaba's largest model to date ranks second only to Anthropic's Fable 5 on Arena.AI, with open weights due next week.

China's open-weight strategy is pulling US developers toward cheaper Chinese models — and 25 tech companies want Washington to keep hands off.

Moonshot's Kimi launch triggered a familiar Silicon Valley freakout — and a lobbying push that would conveniently sideline the frontier labs' cheapest competition.

Little Tech Association pushes back on Anthropic-led calls to restrict Chinese models; Bill Gurley and Chamath Palihapitiya break with frontier labs.

After Moonshot's Kimi K3 rivaled top US models, the Trump administration is weighing presidential action while Commerce pushes back.

Lucas Atkins, whose US lab competes directly with Qwen and Kimi K3, argues a ban would hurt American AI more than help it.

Bessent says Washington will examine open-source models from China for stolen IP, days after reports of a possible wholesale ban.

Six of OpenRouter's top 10 tools are already Chinese. The latest releases from Moonshot and Alibaba shouldn't be shocking anyone.

Kimi K3 lands at 2.8 trillion parameters, Qwen3.8 at 2.4 trillion, and both will release weights that US labs keep locked down.

The Chinese lab's next open-weight model will run 2–3 trillion parameters, the largest ever released from China.

The Beijing lab's valuation has doubled to $20B in months as its Kimi K2.6 model becomes the second-most-used LLM on OpenRouter.
