A Night at the LLM Zoo: Data Conditioned Flow Matching for Generating Pretrained LLM Weights

arXiv:2611.07103v1 Announce Type: new Abstract: A challenge to Weight Space Learning as it expands from task specific and vision models to Large Language Models (LLMs) is the absence of a well curated and analyzed LLM population. To address this, we train such a model zoo for application to Weight Space Generation by systematically varying the data mixture composition between web text, books, mathematics, coding, and French across populations of 51M, 124M, and 355M parameter GPT-2 Models, each tier with count N = 100. We analyze these populations by cosine similarity, functional diversity, Leave-One-Mixture-Out modeling, and variance decomposition. We show that the zoo contains diverse models whose variation is structured by training mixture composition. We embed the training mixture composition to condition a Flow Matching model of complete pretrained LLM weights in Gram-PCA compressed weight space. By demonstrating zero-shot generalization to held out mixtures, measuring Continuous Ranked Probability Score skill, as well as finding minimal changes in downstream test-set perplexity and general capability benchmark scores, we show that our generator generalizes on the simplex of data mixtures to produce models that perform similarly to those in the zoo ex nihilo. Finally, we produce all source code and artifacts to support the continued expansion of Weight Space Learning and Generation into the LLM domain.

Gemini Omni 1.2 Flash: Fast and cost-effective with longer clips

Google DeepMind has launched Gemini Omni 1.2 Flash, introducing native 15-second video generation, improved reference adherence, stronger consistency across frames, multi-turn conversational editing, more natural speech, and cinematic camera movements. The model is now generally available via the Gemini API and Gemini for business, priced at $0.07 per second for 720p video—30% lower than its predecessor. It supports scalable workflows, including draft generation at lower resolutions, iterative edits, and upscaling to 1080p or 4K. Use cases include product explainers, social ads, virtual try-ons, and branded content, with applications across Google AI Studio, Google Cloud, Google Vids, Flow, the Gemini app, and Google Ads.

From Large Language Models to World Models

Yan Deli, a senior expert at Tencent: LLMs are probabilistic models. They do not truly understand language; rather, they predict the next token (Next Token Prediction). Essentially, they are monotonous “word-chain” machines—moving forward one step at a time without retracing their path. At their core, LLMs are probabilistic models that learn, from statistical co-occurrence patterns, “what often appears alongside what,” and output “this is usually the case,” without grasping “why it is so.”...

AI’s Double 11 Puzzle: Merchants Have Paid, Users Are Just Hunting for Freebies

During the 2026 Double 11 shopping festival, AI commercialization showed marked differentiation: on the merchant side (e.g., Qwen Office for E-commerce), paid adoption has already taken hold, with 20% of paying users coming from the e‑commerce sector; on the consumer side, order placement is driven by subsidies offered through distribution channels such as DouBao and Qwen, resulting in a price gap of 37.5%, yet user trust remains low (only 16.06% believe AI can accurately match products), and AI‑powered shopping assistants have not yet truly replaced traditional decision‑making pathways.

Why it matters：The material is based on an in-depth report published by Titanium Media on October 26, 2026, which systematically reviews three categories of AI applications during Double 11: ① AI-powered shopping assistance penetrating the transaction stage (with DouBao/Qwen supporting order placement and payment); ② Token services launched on Tmall and JD.com (with first-day GMV up 450% year-over-year, though sales remain in the early stages); and ③ Merchant tools leading the way in monetization (with clear examples of cost reduction through Qwen Office, integrated into Alibaba’s business systems). All facts are drawn directly from the timeframes, data, and sources explicitly disclosed in the article, with no external inferences.

NVIDIA Cosmos Platform Upgrade: New Toolchain for Training, Evaluating, and Deploying World Models

NVIDIA has expanded the Cosmos platform by introducing the Cosmos Data Factory blueprint, the Cosmos Framework training optimization tool, and the Cosmos 3 NIM microservice, supporting multimodal data generation, adaptation to open-source world models (such as GR00T and QWEN), and low-latency inference; real-world applications have already been deployed by Porsche, ANYbotics, Ultralytics, ADNOC, and others.

DeepSeek V4.1 Flash, MiniMax M3.1 Flash, and Mercury 3 were released simultaneously, as debates over AI infrastructure and governance continue to intensify.

From October 16 to 19, 2026, three new models—DeepSeek V4.1 Flash 1017, MiniMax M3.1 Flash (Space Bunny), and Mercury 3 (Inception)—were released in quick succession. At the same time, the U.S. Department of Homeland Security ordered a ban on DeepSeek-related products, while China is drafting export control regulations for ultra-large-scale models, bringing the conflicts among the open-source ecosystem, computing infrastructure, and AI governance into sharp focus.

llm-meta-ai 0.2

Release: llm-meta-ai 0.2 Meta AI release Muse Wonder (and Muse Wonder Full), their new "most capable models". These look like they may be Meta's first Fable class models - Artificial Analysis scores Muse Wonder (Max) as equivalent to GPT-6.1 Sol. I updated my llm-meta-ai plugin for the new model. Here are pelicans for Muse Wonder for the six reasoning levels: minimal, low, medium, high, xhigh, max. This is the max one: For comparison, here are pelicans for Muse 1.3 (released September 2nd) and Muse 1.2 (released August 5th). Meta AI are putting out a new model a month, and the improvements between each model (at least in terms of drawing pelicans) are material.

Qwen2.5-Max: Exploring the Intelligence of Large-scale MoE Model

QWEN CHAT API DEMO DISCORD It is widely recognized that continuously scaling both data size and model size can lead to significant improvements in model intelligence. However, the research and industry community has limited experience in effectively scaling extremely large models, whether they are dense or Mixture-of-Expert (MoE) models. Many critical details regarding this scaling process were only disclosed with the recent release of DeepSeek V3. Concurrently, we are developing Qwen2.
