- Six Chinese Open-Weight Models Carry a Blackwell Fingerprint, an Independent Weight Analysis Finds, but It Cannot Say Where the Chips Were
Will DePue of Unemployment Labs published an analysis on November 12 arguing that six models released since April 2026 by DeepSeek, Moonshot AI, MiniMax and Ant Group were initialized on Nvidia Blackwell-class GPUs, which need a U.S. licence for export to China. The method reads leftover starting values in the published weights and matches them to each chip's processor-core layout; earlier models from the same labs read as Hopper. DePue confirmed two matches on physical Blackwell hardware. He says the evidence shows access to the chips, not where they were located, how access was obtained, or whether export controls were violated.
- MiniMax's Open-Weight H3-Image Makes 4K Pictures in Seconds, Under a Licence That Shuts Out the US, EU, UK and Korea
MiniMax released H3-Image on November 11, an open-weight text-to-image and image-editing model built on its H3 family, with a 33.1 billion-parameter diffusion transformer distilled to six sampling steps. MiniMax says it generates a 4096x4096 image in under 10 seconds and accepts up to 16 reference images; those are its own claims. The weights are on Hugging Face under a community licence whose territory excludes the European Union, the United Kingdom, South Korea and the United States, and which requires written authorization above $1 million in annual revenue or for hosted services.
- China's AI Export Draft: DeepSeek and MiniMax Cleared for Overseas Use, a State-Media Account Says, Under Rules Covering 23 Technologies
Yuyuan Tantian, a social media account affiliated with state broadcaster CCTV, says DeepSeek and MiniMax have completed registration and been cleared for open-sourcing and authorized overseas use under China's draft AI export controls, Reuters and PANews report; neither company immediately replied to Reuters. The draft, published Oct. 16 by the commerce and science ministries, adds 23 AI technologies to the export-control catalogue and excludes technology already public through open source or papers. Threshold details come from Bloomberg; we did not read the annex.
- China's Nine Leading AI Developers Published Model-Specific Safety Results for 3.6% of 857 Releases, SemiAnalysis Finds
SemiAnalysis reviewed 857 model releases from 2021 to Sept. 15, 2026 by nine leading Chinese developers and found 31 (3.6%) with a published safety-evaluation result tied to that specific model, and nine (1.1%) with results available at or before launch. It found no safety disclosure for 813 releases, which does not mean they were untested. The report gives no comparable figure for U.S. developers, so it measures disclosure in China, not a gap with the U.S.
- MiniMax M2.5 Pitches Lower Output-Token Costs With Vendor Coding Results
MiniMax released M2.5 and M2.5 Lightning (Feb 12): vendor SWE-Bench Verified 80.2%; Lightning ~100 tok/s at $0.30/$2.40 per MTok. Model weights are on Hugging Face under MiniMax’s published license terms; positioned for continuous agents ~$1/hr in company estimates. Cost-per-task is the trade—not another Elo screenshot.
