    AI Weekly: Meta's Muse surpasses 10 million downloads; CXMT and Micron diverge on technology

    Meta's AI assistant Muse has accumulated 10.9 million downloads since its September launch, of which 10.2 million came from the United States, making it one of the mobile apps to surpass 10 million U.S. downloads within 40 days of launch. DeepSeek open-sourced its inference framework DeepInfer and disclosed that a single cluster serves a throughput of 155 trillion tokens per day, with revenue of $38 per card per hour. Anthropic launched Claude Duet, a personal agent based on Claude Opus 5.5, opening research preview waitlist applications to Claude Pro and Max subscribers in the United States.

    Sebastian Raschka releases an 11-hour video course on building a reasoning model from scratch

    Sebastian Raschka has released 8 programming videos on building a reasoning model from scratch, totaling 11 hours, using Python and PyTorch to implement evaluation, inference-time scaling, reinforcement learning, and distillation starting from a pretrained Qwen3 0.6B model. The course first builds a math answer verifier and evaluates on MATH-500, then implements temperature sampling, top-p filtering, and self-consistency, followed by RLVR training with a simplified version of GRPO, and finally distills a small model using answers generated by DeepSeek R1. The content accompanies his book "Build a Reasoning Model (From Scratch)"; the early text generation and evaluation examples can run on a CPU, while later training experiments are recommended to use a GPU.

    CAICT report: Large model token prices doubled compared with the second half of last year, average daily consumption up 3x

    The Institute of Artificial Intelligence of the China Academy of Information and Communications Technology and other institutions jointly released the "Large Model Token Service Performance Monitoring Report (2026)", showing that domestic token prices doubled compared with the second half of last year, with the normalized average price rising from 6.8 yuan to 13.46 yuan, while in June 2026 domestic average daily token consumption was about 500 trillion, nearly 4 times that of December 2025. In terms of performance, in August the average TPS of domestic models reached 78.23, doubling the 2025 average of 38.25, but the average TPS of typical foreign models was 112.82; the domestic first-token latency rose to 1.26 seconds. The report also compared four open-source models, DeepSeek, Qwen, GLM and Kimi, and found that the TPS gap for the same model across different platforms can be close to a factor of two.

    6 major AI models tested on 30 scripts: Claude has the most "Shaoxin style" flavor

    Entertainment Capital had Doubao, Kimi, DeepSeek, GPT, Qwen and Claude each write 5 episodes of a restaurant business-war short drama, 30 scripts in total. Claude was deemed to have the most "Shaoxin flavor," with dialogue rhythm and functional roles such as apprentices and disciples closest to existing Shaoxin short dramas. Doubao came second, more like a punchline generator, but three versions of its scripts never specified what the shop sells. Across the 30 scripts, "conscience" appeared in all of them, "rules" appeared in 80% of the scripts, while the word "Shaoxin" did not appear even once.

    Huawei obtains $2.25 billion seven-year offshore loan from six Chinese banks

    Huawei has obtained a $2.25 billion seven-year offshore loan from six Chinese banks, with the funds to be used for AI chip R&D, research, and inventory stockpiling for storage. Even as buyers such as DeepSeek plan large-scale deployment of its accelerators, production output remains strictly limited. Huawei's R&D investment in the first half of the year was $17 billion, with negative cash flow reaching $5.6 billion.

    Yuyuan Tantian explains the rumors of China's AI technology export ban

    In response to outside claims that China is about to shut the door on AI technology exports, Yuyuan Tantian sorted through the background and regulatory boundaries of the public consultation opened on October 16 by the Ministry of Commerce and the Ministry of Science and Technology on revising the Catalog of Technologies Prohibited and Restricted from Export in China. The article points out that regulation focuses on three categories of technology: data security, sensitive uses, and computing power foundations. When enterprises use restricted large models to provide external API calls, APP/webpage interaction, SaaS applications, and the like, this does not fall within the scope of large-model technology export management; open-source technologies and specific international businesses are eligible for facilitation measures such as automatic licensing. The article also mentions that two companies, DeepSeek and MiniMax, have completed registration procedures and finished open-sourcing and overseas authorized use.

    LMSYS Releases SGLang AWS Trainium Plugin Beta

    LMSYS, in collaboration with AWS, has released the SGLang Trainium plugin Beta, built on the newly released TorchNeuron, supporting LLM inference serving and RL rollout generation on Trainium2 and Trainium3. Initial coverage includes Qwen3 (dense), Qwen3-MoE-30B-A3B, DeepSeek-V2-Lite, GLM-4, and GLM-5.2/5.3, and supports data parallelism, tensor parallelism, expert parallelism, Radix Cache, BF16/FP8, and asynchronous scheduling. In the first end-to-end heterogeneous RL run, SGLang generated rollouts for Qwen3-MoE-30B-A3B on Trainium3, while Miles trained a GRPO policy with Megatron on a single H200 node. The Beta is currently limited to a small number of teams.

    New paper proposes BackUpper: making coding agents back up before they act

    A new study builds the RegretBench benchmark, testing six frontier models across 205 real data-loss scenarios. Results show agents complete tasks at an average rate of 86.1%, but back up before critical operations only 15.2% of the time—GPT-5.6-Terra at 4.4%, GPT-5.6-Sol at 5.9%, Gemini 3.7-Flash at 2.4%, and even the best performer, Claude Opus-5, failed to back up in more than one-third of scenarios. The authors' proposed BackUpper runs in parallel with the agent as an external plugin, using a four-tier strategy: replacing destructive commands, pairing backup commands, generating snapshots, or calling the GPT-5.6-Luna sub-model to determine which data needs saving. In testing it covered all critical operations, with recovered data averaging 92.2% similarity to the original state, at an additional cost of $0.014 per task. BackUpper already supports Claude Code, Codex, Hermes, OpenHands, DeepSeek Harness, and OpenClaw, and its code and dataset have been open-sourced.

    AI Tries to Take Over Scanlation Groups' Jobs, Only to Find They Don't Rely on Translation to Make a Living

    Models such as DeepSeek, GPT, and Qwen can already handle the collection, upscaling, translation, and typesetting of manga scanlation, but when they encounter explicit content or copyrighted content they refuse to translate outright, so a "human feedback" step is still needed to fill the gaps. The work of scanlation groups has therefore shifted to proofreading tone, handling puns and cultural references, adjusting for differences between Chinese and Japanese typesetting, and even drawing clothes onto exposed characters to pass review.
