01What is MiniMax M3 and how does it work?

MiniMax M3 is a new open AI model from the company MiniMax in Shanghai. It is special because it can do three things at once: write code, read long text, and look at pictures. Most AI models make you pick one thing, but M3 does all three in one model.

It works by using a trick called Minimax Sparse Attention. This makes it faster on big jobs. For SEO, you can give it your whole website and it reads everything at once.

Then it can fix problems or write content for you.

02Three key features of MiniMax M3 for SEO

MiniMax M3 has three main features that help with SEO work. First, it can code like a real software person. Second, it can hold 1 million tokens, which means it reads your entire website at once.

Third, it is multimodal, so it can see pictures and video.

  • Coding: It can fix broken links, slow pages, messy code, and missing schema on your site.
  • Long context: With 1 million tokens, you can dump your whole site in and it reads it all in one go.
  • Vision: Show it a screenshot of a Google search page or your homepage, and it understands the layout and design.

These features make M3 a strong tool for technical SEO, content creation, and competitor analysis.

03How to set up and get started with MiniMax M3

Getting started with MiniMax M3 is straightforward, but you need some technical know-how. The weights are open, meaning you can download the model and run it on your own computer. Here are the steps:

  1. Check that your computer has strong hardware, like a good GPU, because running M3 takes power.
  2. Go to MiniMax's official site or a trusted AI model repository to download the M3 model files.
  3. Install the software you need to run AI models, such as Python and a model runner like PyTorch or Hugging Face.
  4. Load the M3 model into your environment.
  5. Start with simple prompts to test it, like asking it to read a web page or fix a piece of code.

Remember, this is not magic. You need some setup work, but it gives you full control over the model.

04How to use MiniMax M3 for SEO tasks

In this episode, Julian Goldie showed several ways to use MiniMax M3 for SEO. You can copy these prompts for your own site. First, for content at scale, say: 'Write me ten blog posts for the AI Profit Boardroom.

Each one should target a different keyword about AI automation. Make them helpful, simple, and built to rank on Google.'

Second, for a full audit, say: 'Read the entire AI Profit Boardroom website. Find weak pages, thin content, and missing keywords. Give me a priority list of fixes.' Third, for an agent job, say: 'Go through the AI Profit Boardroom site.

Find the broken pages. Fix the code. Test it.

Then write me a report on what you did.' M3 can work as an agent and run for hours on its own.

05Results and comparisons from the episode

MiniMax says M3 scored 59% on a coding test called SWE-Bench Pro. That test gives the AI broken websites or bugs and asks it to fix them. That score is a tiny bit higher than GPT 5.5.

But it still sits behind Claude on that same test.

Important to know: those numbers come from MiniMax's own tests, so take them with a grain of salt. Still, for an open model, beating GPT is a big deal. The episode also mentions that M3 is about 15 times faster at giving answers and almost 10 times faster at reading on huge 1 million token jobs, compared to other models.

06Tips, limits, and mistakes to avoid

One big tip from the episode: use M3 for technical SEO tasks like fixing broken links and slow pages. It saves you hours of boring work. Another tip: use the vision feature to analyze competitor pages.

Show it a screenshot of a page that ranks #1 and ask it why that page ranks. Then ask how you can beat it.

Avoid thinking M3 is completely free. The weights are open, but you need strong hardware to run it. Also, the benchmark numbers come from MiniMax itself, so they may be biased.

And M3 still trails Claude on coding. Finally, content alone is not enough. You still need traffic to your site.

Use SEO and backlinks to get found on Google.

07Who should use MiniMax M3 and why it matters

MiniMax M3 is for SEO professionals, builders, and anyone who wants to automate repetitive tasks. If you do SEO, this tool can help you write code, audit your site, and create content fast. It is also for people who want to run their own AI without paying a company every time.

Why it matters: the gap between open and closed AI is closing. M3 is an open model that goes toe to toe with the biggest names. That gives you more freedom and control.

You can build your own SEO robot that does keyword research, writes posts, and checks your site. That is good news for your business.
