    MiniMax 宣布开源 H3 模型,称从 Hailuo 01 到 H3 一路与伙伴同行,开源旨在让更多人共同构建、加速进步。引用推文补充,Hailuo 01 于 2024 年 8 月发布,Hailuo 02 于 2025 年 6 月发布,MiniMax H3 于 2026 年 7 月推出。

    引用Leanna Ren@RenLeanna

    People who know me well know that both @Hailuo_AI and @MiniMax_AI have been my treasures since day one (especially Hailuo)! I’ve been incredibly lucky to witness and help drive its journey from 0 to scale. Many of the friends and peers I’ve met along this journey have also become key forces shaping this industry. There’s no better feeling than getting to grow and progress together. Built on countless hours, deep dedication, and collective intelligence, we’ve grown alongside the AI creative industry, and it has shaped us in return. Making it open is also our determination to help drive the ecosystem forward and accelerate technological innovation. As I said earlier: from today on, we won’t be the only ones here for sure. And that makes me even more excited for what’s ahead. The best is always yet to come. Cheers! 🥂 p1: Hailuo 01 (August 2024) p2: Hailuo 02 (June 2025) p3: MiniMax H3 (July 2026)

    Markopolo AI 发布 4B 参数大型事件模型 Athena(mvrko-sim-1),在 OPeRA 基准的购物行为预测任务中以 24.50% 严格精确匹配率超越 GPT-5.6、Claude Opus 4.8 等前沿模型。Athena 是 Qwen3-4B 的 LoRA 微调模型,可自托管,能预测购物者下一步浏览器动作及目标元素,为下游系统提供实时响应机会。

    引用Tasbin@ttasbin

    Today, we’re releasing Athena (mvrko-sim-1), the flagship Large Event Model from @markopolo_ai that beats GPT-5.6, Claude Opus 4.8, and Claude Sonnet 5 in OPeRa public benchmark for Shopping behaviour prediction! Athena introduces a completely different approach to understanding digital behavior. Most systems record actions after they happen. Athena models the sequence behind them to predict what a shopper will do next and exactly where they will do it, before the action even takes place. Athena vs. frontier models: We evaluated Athena on the full OPeRA test set alongside GPT-5.6, GPT-4.1, Claude Sonnet 5, and Claude Opus 4.8. Athena achieved 24.5% strict exact match scoring the highest among the five models evaluated. Athena is not a general-purpose language model. It is a Large Event Model built to understand behavior as a connected sequence. It combines the page someone is viewing, the actions that brought them there, and the goal they are trying to complete and then predicts the exact next browser action and target element. That distinction matters. Today’s digital systems largely react after someone clicks, abandons, purchases, or leaves. Athena creates the foundation for systems that can understand what is likely to happen before the outcome. Together with @RubaiyatFarhan, and the team at @markopolo_ai, we built Athena from years of work on shopper behavior, digital journeys, and behavioral intelligence. Commerce was our first proving ground. Great thing is, we’re now releasing Athena publicly so builders can adapt the model to new datasets, industries, and problems. We’re seeing early usecases in Cyber Security, Gaming, Mobile App Ecosystem, Retail and more! Athena is now live on Hugging Face! We built the foundation for relevance and predictability! Now, let’s see what the world builds on top of it. Links in the first reply.

    MiniMax H3 权重正式开源,并在发布当天(Day 0)原生集成到 ComfyUI,支持文本生视频、图像生视频、首尾帧控制、参考视频及就地编辑五种工作流。H3 以多模态上下文理解为核心,可同时处理图像、音频和视频,并依据提示词解析其关联。

    引用ComfyUI@ComfyUI

    MiniMax H3 is native in ComfyUI, day zero with the weights. Model highlights: → Text-to-video, prompt only → Image-to-video → First-and-last-frame - control the opening frame, the closing frame, or both → Reference-to-video - carry a subject, a motion, or a voice through the clip → In-place editing - modify a shot you already have instead of regenerating it The capability @MiniMax_AI leads with is multimodal context understanding, and it's what collapses those five tasks into one model. H3 takes images, audio, and video together and resolves them against a prompt that explains how they relate. Download the workflows & learn more in our blog 👇
