Moonshot AI has open-sourced Kimi K3, a 2.8T-parameter model it calls the first open "3T-class" AI. It posts 88.3% on Terminal-Bench 2.1 (half a point behind GPT-5.6 Sol, ahead of Claude Fable 5 and Opus 4.8) and trades blows with frontier closed models Claude Fable 5 and GPT-5.6.
Meta CEO Mark Zuckerberg said banning Chinese AI models is "not an effective solution" and warned against "regulatory capture," calling for fewer barriers. A coalition of 20+ tech companies released a joint letter urging policymakers to avoid restrictions on open-weight AI models, arguing openness expands access to the AI economy.
Nvidia led an $800M round in Reflection AI, positioning it as a champion of Western open-source AI in direct response to China's rapid advances (DeepSeek, Kimi K3). The bet underscores that open-source AI is now a strategic front in the US-China AI race.
Samaya AI released FrontierFinance, a new public benchmark for AI agents in investment workflows. Samaya's own system outperformed Claude Fable 5 and GPT-5.6 Sol; the evaluation included open-source models GLM 5.2 and DeepSeek alongside frontier closed models from Anthropic, OpenAI, and Google.
Vox reports Chinese companies released two models - Kimi K3 and Qwen3.8 Max - that are nearly as powerful as ChatGPT and Claude but much less expensive, pressuring OpenAI and Anthropic's closed-loop business model. GLM-5.2 already offers a one-million-token context and open weights at lower economics.
Amazon is phasing out most of its Nova AI models and redirecting talent to a single frontier effort, signaling that model quality now matters more than portfolio size in the AI race.
Samsung secured a Broadcom AI chip manufacturing deal worth more than $200B through 2030, and reported Q2 operating profit that beat estimates on soaring AI server demand, with all-time high DRAM and NAND sales. Samsung also warned chip supply shortages will worsen due to the AI boom.
