MiniMax-01: Scaling Foundation Models with Lightning Attention

We introduce MiniMax-01 series, including MiniMax-Text-01 and MiniMax-VL-01, which are comparable to top-tier models while offering superior capabilities in processing longer contexts. The core lies in lightning attention and its efficient scaling. To maximize computational capacity, we integrate it with Mixture of Experts (MoE), creating a model with 32 experts and 456 billion total parameters, of which 45.9 billion are activated for each token. We develop an optimized parallel strategy and highly efficient computation-communication overlap techniques for MoE and lightning attention. This approach enables us to conduct efficient training and inference on models with hundreds of billions of parameters across contexts spanning millions of tokens. The context window of MiniMax-Text-01 can reach up to 1 million tokens during training and extrapolate to 4 million tokens during inference at an affordable cost. Our vision-language model, MiniMax-VL-01 is built through continued training with 512 billion vision-language tokens. Experiments on both standard and in-house benchmarks show that our models match the performance of state-of-the-art models like GPT-4o and Claude-3.5-Sonnet while offering 20-32 times longer context window. We publicly release MiniMax-01 at https://github.com/MiniMax-AI.

Host: Hey everyone, and welcome back to the podcast! I'm your host, Leo, and I'm super excited about today's topic. We're going to be diving into something that’s a cornerstone of the academic world, something that many researchers, students, and even curious minds like you and me, use daily.

Host: I’m talking about arXiv, that massive online repository where so many cutting-edge research papers are shared. Think of it as the ultimate preprint server for science and math. It’s pretty foundational for how scientific knowledge disseminates these days.

Guest: Absolutely, Leo. And it's not just a repository, is it? It's almost become a kind of culture, a way for academics to quickly share their work and get feedback, before the often slow peer review process. It has fundamentally changed how scholarly communication works, and I think many people, even those who interact with it regularly, might not realize just how profound its impact has been.

Host: Yeah, that’s so true. It's easy to take it for granted now, just going to arXiv and downloading papers. But it really revolutionized things. Before arXiv, researchers were relying on physical mail, expensive journals, and conferences for sharing their findings, and the process was often slow and cumbersome. The speed with which research is now accessible has definitely accelerated the progress of science. Think about how quickly a new idea in, say, AI can spread throughout the research community; it’s because of this kind of open access.

Guest: Exactly! And it’s not just about speed either. It's also about accessibility. For researchers in less well-funded institutions, or in developing countries, access to journals can be prohibitively expensive. arXiv provides a free, open platform, really leveling the playing field and promoting a more democratic exchange of ideas. That’s a massive benefit for global scientific progress.

Host: Totally agree. It also impacts the way that research is being developed. Instead of waiting for months or years to get something published in a traditional journal, researchers now can share a preprint right away, get early feedback, and refine their work. I mean, it's almost like real-time collaborative research at a global scale, isn't it?

Guest: It is, and it also feeds into the trend toward open science and reproducible research. Because it's so easy to share a preprint, it encourages researchers to be transparent and provide access to their underlying data, methodologies, and even code. The whole process becomes more collaborative, not just in receiving feedback, but also in building upon the prior work.

Host: And let's not forget the sheer volume of papers. It's truly astonishing how many preprints are uploaded every single day. I was actually just looking at a recent paper, and I noticed it was a 'no HTML available' entry on arXiv. It kind of made me wonder about the whole process of submitting papers and different formats that are used on arXiv, and the potential issues that arise with that.

Guest: That's an interesting point, Leo. That 'no HTML available' message is something many users will have come across. It typically means that the original source files weren't in a format that arXiv could directly convert to HTML, like if it was just a scan of a document, or an unusual LaTeX format or something like that. Most of the submissions are in LaTeX, which is pretty much the standard for math, computer science, and physics, but sometimes you'll see other formats, and the HTML version becomes harder to process, or they might not provide a version at all. This can definitely create a bit of a challenge in terms of accessibility for some users, especially those who are not used to viewing the raw formats, like PDF, or don’t have the tools readily available to do so.

Host: Right, and I guess that highlights the importance of not just making the research accessible, but also making it easily consumable. I'm also thinking about how arXiv is maintained and what it takes to keep it running smoothly. It's a massive project, and obviously, it's not just magically appearing there. There's infrastructure, people, and definitely costs involved.

Guest: Oh, definitely. It’s a huge undertaking. arXiv is not just some static website, there's a whole backend system managing the submission process, the automatic formatting conversions, indexing of articles, not to mention keeping everything secure and reliable. And you're right, this all costs money, from the servers, the staff, to the development of new features and dealing with the increasing volume of content. That's why they rely on the support of the Simons Foundation, member institutions, and contributions. It’s important to note that it’s not funded by a major scientific publisher or something like that. It is more in the nature of open non-for-profit collaboration.

Host: Yeah, that makes sense. I remember seeing a link for donations on the page and it really emphasizes its community-driven nature. And it's also impressive how they’ve managed to keep it running so efficiently for so many years. When you look at the bottom of the page, there's all this information about copyright, privacy policies, accessibility, and operational status – it really shows how much thought goes into the overall platform. It is far more than just an online filing cabinet for research papers.

Guest: Absolutely. And those links are crucial, especially in a time when concerns about copyright, privacy, and accessibility are paramount. It shows that the people behind arXiv are conscious of the bigger picture, how the platform fits into the broader scholarly communication landscape and the needs of researchers worldwide. For instance, web accessibility is not an afterthought, it's an integral part of the design. And the operational status page, with its real-time updates and subscription options, is crucial to keep users informed of any issues or planned maintenance, showing the seriousness with which they maintain the platform.

Host: Yeah, I agree. It also shows a level of transparency that's often lacking in many other online platforms. I think the 'contact' and 'subscribe' links at the bottom also reflect a commitment to communication and community building. It’s almost as if they're actively inviting feedback and engagement with the users. This might seem like small details, but they all contribute to making arXiv more of a shared space rather than a simple tool.

Guest: That's right, and it's this kind of community-driven approach, I think, that makes arXiv so valuable. It's not just a place where researchers deposit their work, it's a platform that fosters connections, collaborations, and ultimately, helps advance knowledge. And the fact that it has been around since the early '90s, when the internet was still in its infancy, speaks volumes about its staying power and relevance. I think a lot of researchers just treat it as a basic component of the workflow without acknowledging the significance of it all.

Host: Definitely. It really has become an indispensable tool, a kind of academic lifeline, especially when the traditional publishing route takes so long. You know, when you think about it, arXiv has been at the forefront of promoting open access, influencing the whole scientific publishing landscape and even forcing the larger scientific publishing corporations to rethink some of their strategies. This has resulted in open access policies in many countries, and the whole process of research dissemination has become far more transparent because of it.

Guest: Absolutely. It's also important to consider the impact on researchers' careers, particularly for early-career scientists. The ability to share their work quickly on arXiv, gain citations, and demonstrate productivity, can make a huge difference in their visibility and opportunities, often long before their peer-reviewed papers are formally published. The system has its critics, of course, with the main concern being the reliability of papers that haven't undergone peer-review, and the potential for spreading flawed or preliminary findings, but I think the community has been very effective at self-regulating and finding a balance between speed and rigor.

Host: That's a really good point. The speed factor can be both a blessing and a curse. On the one hand, you have immediate access to cutting-edge research; on the other hand, it's not always as polished or as thoroughly vetted as a peer-reviewed paper. So it's important to approach arXiv preprints with a critical eye, always considering them as work in progress. But, of course, that’s a good skill to learn anyway.

Guest: Precisely. It encourages a kind of active reading and engagement with the research, rather than passively accepting findings as definitive. It also facilitates a very important dialogue among researchers, allowing them to discuss early findings, propose improvements, and challenge claims. This constant cycle of feedback and refinement is, in many ways, the lifeblood of scientific progress, and arXiv is at the center of it. And, I think it’s interesting to look into the role of moderation that exists within the arXiv itself. It is not just a free-for-all where anyone can upload anything, there is some level of control and quality assurance, but not peer review itself.
