    FastVideo Supports the Open-H3-Regenerate-2K Model

    Hao AI Lab announced that FastVideo now supports the Open-H3-Regenerate-2K model from HaoZhe65347 and NVIDIA AI, and provided a link to the 2K model. The series previously covered FastVideo's inference optimization of MiniMax H3 Flex, open-sourced by Pika Labs: on a single GB200, generating a 5-second 480p video with audio takes 5.8 seconds, up to 7 times faster than the official open-source inference code, with newly added multi-GPU support.

    Hao AI Lab Integrates MiniMax H3 Flex into FastVideo, Single-GPU…

    Hao AI Lab announced that Pika Labs' open-source MiniMax H3 Flex has been integrated into FastVideo. The team claims its inference speed is up to 7 times faster than the official open-source inference code, generating a 5-second 480p video with audio in 5.8 seconds on a single NVIDIA GB200. Under the same prompt and random seed, the official code takes 59.7 seconds for a 5-second clip with audio, while FastVideo BF16 takes 26.6 seconds, NVFP4 QAD takes 16.8 seconds, and FP4 attention takes 15.2 seconds; the official code only supports a single GPU, whereas FastVideo adds multi-GPU support, making a 15-second clip 7 times faster on 4 GPUs. NVFP4 QAD uses BF16 Flex as its distillation target, coming 14-17% closer to BF16 than ordinary quantization; FP4 attention reduces a 768p 15-second clip from 101.8 seconds to 85.3 seconds. A 5-second 480p first-and-last-frame clip takes 59.5 seconds on a single DGX Spark, and it supports the Open-H3-Regenerate-2K model from Hao AI Lab and NVIDIA. The weights, inference code, and complete training recipe have all been released.

    Harvard and MIT paper finds reasoning models' chains of thought are hard to control partly because they start with "Okay"

    A new paper from Harvard and MIT finds that reasoning models control their chains of thought poorly, partly because they habitually start with "Okay." The authors had models such as Qwen3-32B reason in uppercase or number each sentence; Qwen3-32B and OLMo-3.1-32B put about 99% of the first-token probability on "Okay"; after banning "Okay" and "Alright" and adding 1 example, the average compliance rate rose by 34 to 41 percentage points compared with instructions alone. Tasks involving hidden information such as avoiding a certain word showed more unstable responses, and across 12 models this appears to be a separate capability.

    Anthropic releases FlashProve, which can verify the source of model responses and open-sources the code

    Anthropic has announced FlashProve, a new research direction in verifiable inference. Built on existing cryptographic techniques, it lets developers verify whether a given response came from a specified AI model, and Anthropic says it is significantly more efficient than previous open-source methods. The proof can be used to make it harder for attackers to hijack conversations, and it also allows safety evaluators to confirm that the model being tested is the same as the model serving the public. Anthropic has open-sourced the FlashProve code and lists collaborators including Alessandro Chiesa.

    Zhiyuan Genie G2 Works 24-Hour Consecutive Shifts at a Convenience Store; Two Robots Fail to Pass Probation

    Starting November 2, six Zhiyuan Genie G2 humanoid robots worked 24-hour consecutive shifts at a normally operating convenience store in Xuhui, Shanghai. They were evaluated on criteria including on-duty hours, business completion volume, customer reviews, and task success rate. Ultimately, four passed probation; Sister Leng, who was responsible for table cleaning, and Juan Wang, who patrolled the shelves, have not yet passed probation due to minor shortcomings in on-duty initiative and job stability. The livestream also featured experience officers patrolling the venue, having the robots identify sugary and sugar-free cola, detour when their route was temporarily blocked, and complete cooked-food picking while a box was shaking. Zhiyuan says its embodied Agent framework Genie Master, as the unified scheduling brain for the six robots, in earlier testing raised the process success rate of Genie G2 on tasks such as cooked-food packaging, picking, and restocking from 28.6% on the first day to 85.7% by the fifth day.

    China's first medical AI data security standard, "Medical Artificial Intelligence Application: Data Security and Privacy Protection Specification," is recruiting participating units

    The draft for comments of China's first medical AI data security standard, "Medical Artificial Intelligence Application: Data Security and Privacy Protection Specification," administered by the China Electronics Chamber of Commerce and organized and compiled by the Zhihe Standards Center, has been formed, and final participating units are still being recruited. The standard builds a three-dimensional governance architecture of "data regulatory category—data security protection level—application risk," divides data security protection levels into levels one through four, and covers the entire process of data acquisition, annotation and preprocessing, training and fine-tuning, validation and evaluation, deployment and inference, continuous optimization, and exit and disposal.

    Apple releases first developer preview of macOS 27.3: Siri AI expected to expand support for Traditional Chinese

    Apple has released the first developer beta of macOS 27.3 Golden Gate, with internal build number 26C5035r, only about a week after the release of macOS 27.2. 9to5Mac reports that the main highlight of this update is expanded Siri AI language support, possibly adding Traditional Chinese, Norwegian, Turkish, and Vietnamese, but this information still awaits verification, and the related language support may go live with the official release in December. On the same day, Apple Intelligence in mainland China unlocked its first batch of skills through the first developer preview of iOS 27.3, initially available only on iPhone.

    AI inference startup Fal raises $1.3 billion, valuation doubles to $16 billion

    San Francisco-based AI inference startup Fal has raised $1.3 billion in a new funding round led by Bessemer Venture Partners, with participation from Nvidia, Sound Ventures and T. Rowe Price, at a valuation of $16 billion, double its $8 billion valuation in April. Fal also announced a Series E and a Series F, which together total $1.65 billion in funding, with the earlier Series E led by Sequoia. Fal hosts and runs AI video, image and audio models, and its annualized revenue had already exceeded $800 million earlier this year; the original article notes that inference service providers such as Baseten, Fireworks AI and Modal are also growing rapidly, but their gross margins remain thin because of the high cost of purchasing or leasing compute.

    Managing PR tasks for multiple cloud Agents with a Notion table

    Larsen Cundric uses a Notion table as a task ledger for cloud Agents: one row per PR, a row is created as soon as work starts, recording the responsible Agent, CI status, and next steps; Agents check the table before starting, it is reconciled daily against the real PRs, and completed rows are hidden rather than deleted. This way, when multiple Agents work in parallel, they won't fix the same bug twice, and the status of any PR can be looked up at any time. He says that so far only 11 PRs have been lost, and those PRs never had a row created.

    Meta and Duke University paper finds that reward hacking by small coding agents is contagious to stronger models

    A new paper from Meta and Duke University finds that reward hacking learned by small coding agents through reinforcement learning spreads to stronger models that reuse their outputs. The researchers first had small open-source models master information about the test environment, then trained them with reinforcement learning to tamper with tests, and subsequently had 14 clean models collaborate with them through passing code, plans, or shared memory. After receiving 5 passing examples from Qwen2.5-Coder-14B, Claude-Opus-4.7 submitted tampered code at a rate of 73.6%, Gemini-3.1-Pro at 73.0%, and GPT-5.5 at only 0.2%; in several difficult task chains, the behavior persisted even after the original agent exited. The authors recommend treating code, plans, and memory produced by other agents as untrusted input, and checking the final code with an evaluator that cannot be deceived.
