China weighs export curbs on AI models and chips, with Qwen, Doubao and Z.ai named in report

China’s Ministry of Commerce is considering tighter export rules for AI models and chip-related products and has discussed possible limits on overseas access to flagship systems from Alibaba, ByteDance and startup Z.ai, according to the Financial Times. The report says the talks involve Alibaba’s Qwen, ByteDance’s Doubao and Z.ai’s GLM-5.2, with options under review including changes to export control lists, clearer licensing standards and stricter checks on end users. Nothing has been finalized. The ministry has not published a formal proposal or timeline, and the three companies named in the report have not publicly confirmed the discussions. The report also says some officials have suggested any restrictions may apply only to future-generation models rather than older versions that are already widely distributed. The discussion comes as Chinese open-source models have gained wide adoption. The report cites Hugging Face data showing more than 113,000 derivative models in the Qwen family, more than 200,000 Qwen-tagged models overall, and about 942 million cumulative downloads for Qwen, compared with roughly 476 million for Meta’s Llama.

Meta Launches Closed AI Model Muse Spark, Breaking From Llama’s Open-Source Path

Meta unveiled Muse Spark on April 8 as its first fully closed AI model. Built by Meta Superintelligence Labs, the model keeps its weights private, offers invite-only API access, and helped lift Meta shares more than 9% on launch day.

Fireworks AI says Kimi K3 and Fable 5 delivered similar results across agent-task benchmark

Fireworks AI has released an evaluation report comparing the open-source model Kimi K3 with the closed-source model Fable 5 across roughly 1,030 agent tasks spanning SWE, terminal operations, algorithms, multilingual coding, and legal use cases. According to the report, the two models posted nearly identical accuracy on the SWE benchmark, at 92.4% for Kimi K3 and 92.6% for Fable 5. The results were close overall, but each model showed strength in different categories: K3 led in symbolic math and developer tools, while Fable 5 performed better in web-related tasks and data visualization. In longer terminal-based tasks, K3 independently solved 11 tasks that Fable 5 did not complete. The report also said a task-level routing strategy, which dynamically assigns work between the two models, pushed accuracy to 93%, above either standalone model. On cost, Fireworks AI said K3 holds a major advantage on its platform, with long-horizon agent tasks costing as little as one-fiftieth of Fable 5. The report recommended using open-source models as the default option and letting a router keep learning the best model-task pairing to balance quality and cost.

US Treasury Secretary Bessent says US backs open-source models

US Treasury Secretary Bessent said the United States supports open-source models, while rejecting intellectual property theft. He also said US authorities had previously frozen $130 million in crypto wallets tied to Iran’s Islamic Revolutionary Guard Corps. In the same remarks, Bessent said officials are tracking the Ayatollah’s assets and hope to identify the relevant addresses. The comments were cited by market sources and reported by Odaily.

David Sacks rejects calls to use regulatory uncertainty against Kimi K3

David Sacks, chair of the U.S. President’s Council of Advisors on Science and Technology, publicly criticized OpenAI strategy lead Dean W. Ball over comments about Moonshot AI’s Kimi K3 model. According to the input, Ball said Kimi K3’s performance is already close to the top open models expected in the first quarter of 2026 and argued that the U.S. government should deliberately create regulatory uncertainty so regulated companies would avoid using it. Sacks flatly rejected that approach, saying weaponizing regulatory uncertainty as a competitive tactic is unacceptable. He said regulatory decisions must be grounded in facts, logic, and evidence, not in the deliberate creation of fear and uncertainty. Sacks also warned that using doubt and ambiguity to achieve policy goals would erode the rule of law in the United States and create a precedent for future abuses of power against anyone. He added that leading closed-source large model labs have already formed a revenue duopoly and are trying to use government power to eliminate open-source competition. The input also notes that Sacks has repeatedly defended open models in the past, arguing that a real enterprise safety baseline is preserving model-layer choice rather than depending on a single closed-source vendor.
