US Enterprise Adoption of Chinese Open Weights: Harvey and AT&T Pivot to Kimi K3
The global AI ecosystem is witnessing a historic geopolitical and commercial shift as major U.S. enterprises and cloud giants move to adopt and host leading Chinese open-weight models. Despite intense regulatory scrutiny and export controls in Washington, Beijing-based AI unicorn Moonshot AI has emerged as a key player in the enterprise market, with its blockbuster Kimi K3 model (a 2.8-trillion-parameter open-weight multimodal mixture-of-experts model) gaining rapid traction.
US Cloud Giants Negotiate Kimi K3 Revenue-Sharing Deals
On August 26, 2026, Reuters revealed that Moonshot AI is in active negotiations with U.S. cloud giants Microsoft (Azure), Amazon (AWS), and Alphabet (Google Cloud) to host Kimi K3 on their respective cloud platforms.
Key details of the negotiations include:
- The Revenue Cut: Moonshot is seeking up to a 30% share of revenue generated from K3-related services on Azure, AWS, and Google Cloud. This matches the revenue-sharing terms Alibaba has reportedly outlined for major enterprise users of its own open-source models.
- The Route to Enterprise Adoption: Although Kimi K3 is an open-weight model that can be downloaded locally, its massive 2.8-trillion-parameter scale makes running it on private infrastructure prohibitively expensive. Hosting Kimi K3 on major U.S. cloud platforms represents the primary route to secure, scalable enterprise deployment.
- Unresolved Hurdles: According to sources close to the talks, unresolved issues include the exact revenue split, data access protocols, and auditing token usage (the units of text processed by the model, which are central to calculating usage-based billing).
Enterprise Pivots: Harvey and AT&T
The cloud hosting negotiations follow highly publicized pivots by major U.S. enterprises to integrate Kimi K3 into their production workflows. Notable early adopters include:
- Harvey (Legal AI): The prominent legal AI platform has integrated Kimi K3 to power complex legal document review and multi-step reasoning, citing its superior performance on demanding legal reasoning benchmarks.
- AT&T: The telecommunications giant has piloted Kimi K3 for automated customer service orchestration and code generation, leveraging the model's cost-efficiency and massive 1-million-token context window.
Geopolitical Friction and Blacklist Threats
The commercial success of Kimi K3 and its potential integration into U.S. cloud infrastructure have triggered sharp warnings from Washington. U.S. Treasury Secretary Scott Bessent warned that Moonshot AI could be added to a trade blacklist. Additionally, U.S. officials have accused Moonshot of illegally acquiring Nvidia chips and "stealing" from Anthropic's flagship Fable model to build Kimi K3—allegations Moonshot has firmly rejected, attributing K3's performance to original architectural innovations.
Nonetheless, Kimi K3 continues to deliver stellar results in independent evaluations. It was ranked first on Arena.ai's benchmark for web interface construction, and Artificial Analysis found its multi-step reasoning performance comparable to OpenAI's GPT-5.5 and Anthropic's Claude Opus 4.8.
