🚀我们很高兴开源Hunyuan-GameCraft，这是一个基于HunyuanVideo构建的高动态交互游戏视频生成框架。 它可以从单一场景图像和用户动作信号生成可玩且物理真实的视频，使创作者和开发者能够以第一人称或第三人称视角“导演”游戏。 主要优势： 🔹高动态：将标准键盘输入统一为共享的连续动作空间，实现对速度和角度的高精度控制。这使得探索复杂轨迹成为可能，克服了传统模型的僵硬和有限运动。它还可以生成动态环境内容，如移动的云、雨、雪和水流。 🔹长期一致性：使用混合历史条件，在重大移动后保留原始场景信息。 🔹显著降低成本：无需昂贵的建模/渲染。PCM蒸馏压缩推理步骤，提高速度并降低成本。这使得量化的13B模型能够在消费级GPU（如RTX 4090）上运行。 项目页面： 代码： 技术报告： Hugging Face：

I’m joining @a16z ! After five years at Shopify, I’m moving onto my next adventure in life, and heading to Andreessen Horowitz. Shopify is an incredible place, and Tobi is one of the great founders of our era. I’ll remember those years as one of the golden chapters of my life. Now, onwards! I’m joining a16z as Editor at Large, and I’ll be responsible for the written output of the firm. A16z has always prioritized great thinking and writing as a deliberate instrument of the firm’s purpose and power. It starts with Ben and Marc: both generationally talented high-agency thinkers, writers, and company builders. And there’s a burning new energy in the firm today, brought by @eriktorenberg - who I’ll work with closely as he takes a16z’s narrative presence to a new level of ambition. Writing is power transfer technology I’ve had a few different vocations over the years - I’ve been a founder, touring musician, venture associate, worked at Shopify - but most people on the internet know me from my writing online. I’ve been blogging since my early twenties, and in that time I’ve seen different online content metas come and go - the golden years of VC blogs like AVC and Haystack, the Medium years, now Substack; the rise of “Go direct” and the crisis of traditional media. What hasn’t changed is how valuable great writing can be. Something special happens when you give someone words to express an idea they always knew, but couldn’t articulate: you give them power. And it didn’t cost you anything. “Power transfer technology” is what the business of VC is. Why does a VC firm care about content? It can’t just be to advertise the firm; or promote their partners and their theses. Those are both consequences of success, but they can’t be the actual goal. The primary objective of a VC firm’s content, particularly their written output, should be to give founders power. The goal is to give them writing that transforms them into someone with more legitimacy, which is what power really is about. Traditional media sometimes helps you accomplish this. A well-written op ed, thoughtfully crafted, can serve this purpose. But I think bloggers are naturally better at this craft, because bloggers have to grow their franchises under the constraint of not having built-in distribution. If you’ve mastered the craft of writing online, you know something important about how to reach and influence people, and what exactly it is you offer to an audience that gives them power. Blogging is a trade Winning, for bloggers, means writing the reference take on a good topic. My favourite example of this is how Byrne Hobart broke out with his piece on the 30-year mortgage. It’s kind of surprising that this kind of post had such influence - it’s wonky, it’s not written for a general audience whatsoever. But it turns out that people think and talk about their mortgages a lot, and like to feel competent when they do. Reading that piece equips them with a kind of legitimacy to speak on the topic. One lesson hiding in plain sight here is that most of the audience of any successful post does not actually read it. They are told it by someone who did read it. There’s a primary audience who carefully reads the piece and does the cognitive work of “restructuring their consciousness” (Walter Ong coded) around good writing. And then there’s a secondary audience, who are re-told the content, either verbally (including group chats, podcasts, Youtube) or in other oral formats like Twitter. (This is broadly true both inside and outside of organizations; e.g. a lot of work goes into writing an annual plan, which only a small number of people actually read, but a lot of people are “re-told” in some way.) The primary audience gets something out of this sequence of events: they get power. This is the great secret of writing in public: the writer and primary audience both put in effort (to pack and unpack the idea); and they jointly reap the rewards, which is the legitimacy earned when the idea gets subsequently retold verbally to the wider secondary audience. This is why, paradoxically, to reach the widest audience, you write to the narrow audience. Your objective as a writer is to give your primary audience material they’ll want to re-tell. They do the work of translating it to wider audiences in specific contexts; you do the general articulation in rich detail. The secret of magic is to transform the magician Today, there’s an amazing idea-sharing format that’s swallowed a lot of the “smart people discourse” on the internet, which is podcasting. The rise of podcasts has been astounding to watch, in the six years since I wrote The Audio Revolution. And a16z has both a great past and a great future in this media format, especially with Erik at the helm and seeing the caliber of talent he’s bringing on board his New Media team. But podcasts are not enough on their own. Great writing, which has gone through the crucible of thinking and editing, transfers something into the reader, and transforms something within the reader, that talking does not. I know a lot of smart people who correctly intuit that blogging is powerful, but can’t justify it on a return-on-effort basis compared to other ways of getting their message out. This is a mistake. Writing matters. It takes more effort to read something than to listen to it. (And much more to write something than to talk about it.) The cognitive work of writing and reading is a real cost, but the benefit is that you get “restructured consciousness” from factoring and negotiating with the idea in written form. When you read an important idea and put in the work to understand it, you gain the subconscious competence and legitimacy to talk about it: you are transformed into someone with more power. Whereas, when you hear an idea, you can usually repeat the idea but not with the same authority. The deep competency is not transferred to the same degree. This is an important idea to understand in a world where most of our information diet is shifting towards oral communication in various forms - “the internet village.” Now, people have been complaining that “nobody reads anymore” for decades - the point here is, the benefits of reading have never been more disproportionate, nor less obvious. The farther we move towards being a default-verbal information culture, the more powerful the trade between writer and primary reader, but the less obvious it is to do. (Why write things if people would rather watch or listen?) If your goal is “I want to maximize the number of people who receive my message” then oral formats like podcasts, Youtube, and Twitter will appear like the obvious choice. But if you articulate the goal as “I want to give people power” then clearly you’ve got to write something down. Founders are customers for legitimacy I remember some days when I was a founder and no one would take me seriously, except for when I could produce a blog post from someone like Paul Graham or Semil Shah and speak to that idea. Something incredible would happen in those moments - people would actually listen to me, as if I’d suddenly become magic. Magic works because it is communication. The founder equipped with the VC’s writing should communicate something higher-signal than the founder alone. Ask, “what must be true of the content for this statement to become real?” and you’ve got a good guide for what kinds of things to write. This relationship between VC and founder scales all the way up to real power-politics: the job of the VC firm is to be the “legitimacy bank” where founders (and other high-agency people) can go to take out legitimacy on credit, or make a legitimacy deposit. I find this to be a wonderful way to frame the founder-VC relationship because it does NOT imply the VCs are the “grownups” in some patronizing sense: it celebrates legitimacy as a thing that VCs and founders incept together, just like how blogging is thing that the writers and their primary readers incept together. This is why VC blogs were such a good product in their heyday. As the “free tier” of the VC, it naturally frames the relationship as one where legitimacy is jointly incepted (by the writer and primary reader), not as one that’s benevolently bestowed. The meta is different now, but the purpose is the same, and I think a16z is probably the best spot in the world to pursue that craft and that thesis. I’m incredibly fortunate to get to join this group of talented investors and company builders, towards a mission that’s never been more important: giving the world’s founders the power they need to build a bright future. Let’s go!
