I Tested Minimax M3: The AI That Took Over My Computer
admin I didn’t touch my mouse. I didn’t open my browser. I just watched as an artificial intelligence moved my cursor, navigated websites, and started doing my work for me. The tool behind this isn’t GPT-5.5 or Claude. It’s Minimax M3 — a new open-source AI from China that launched approximately 48 hours before I ran these tests, and it’s already outperforming models that cost 50 times more.
Key Takeaways
- 1 million token context window lets Minimax M3 hold entire codebases, books, or large projects in memory without forgetting details
- 79% score on software testing benchmarks, surpassing GPT-5.5 and Claude 3.1 Pro — despite being nearly free
- Desktop agent capability distinguishes it from chatbots: it sees your screen, controls your computer, and works autonomously
- Multimodal understanding of text, images, video, and live screen capture in a single model
- Cost is “pocket money” compared to competitors — per-million-token pricing in the cents range
- I tested it head-to-head against Claude Opus 4.8 and Codex 5.5 on identical game-building prompts
Why Everyone Is Talking About Minimax M3
Three capabilities converged in this release for the first time, and I believe that’s why it’s causing this level of disruption.
First, the 1 million token context window. I can feed it an entire project — a full book manuscript, a massive code repository — and it retains everything. Nothing gets lost in the middle. For the kind of complex automation work I do in e-commerce and online business, this changes what’s possible.
Second, it’s genuinely multimodal. It doesn’t just process text. It sees images, understands video, and critically — it sees your computer screen in real-time. This isn’t theoretical. When I ran my tests, the agent was literally watching my desktop and making decisions based on what it observed.
Third, the pricing. While competitors charge amounts that make serious automation expensive at scale, Minimax M3 is priced at what I’d call pocket money. Per million tokens, we’re talking cents. There’s even a free tier to start testing the desktop agent. I honestly couldn’t find an excuse not to try it.
The benchmark that stopped me cold: 79% on software testing. That’s higher than GPT-5.5 and Claude 3.1 Pro. An open-source Chinese model beating the most expensive American models on coding tasks — this would have seemed impossible a few years ago.
Setting Up My First AI Employee
Here’s where Minimax M3 diverges from every chatbot I’ve used. It has a desktop application. You install it on your computer, and it becomes what the company calls a “personal assistant” or what I configured — using the Hermes Agent framework — as an autonomous worker.
The fundamental difference from other AIs: it doesn’t just talk. It does the work. The backend contains thousands of capabilities. I connected my files, my email, my calendar. Now it works with my actual data, my actual world — not generic training data.
I gave my agent a specific goal: generate £1 million in sales, and don’t stop until achieved. It will continuously improve itself and scale operations. You can program any life goal this way — write the plan, develop the capability, and the AI works daily toward it.
The configuration requires precision. You define exactly what the agent does, provide detailed descriptions, and specify boundaries — what it should do, what it must never do. You choose between asking permission for each step or granting full autonomous operation. I tested both modes.
Remote control works through Telegram bot, WeChat bot, or Lark. I can monitor and direct my desktop agent from my phone, 24/7, even when I’m away from my computer.
Test 1: Building a Professional Website in Under a Minute
I wrote a single prompt: build me a beautiful gaming website, with all files contained in a single HTML file. I selected Minimax M3 and started the system.
The result loaded in seconds. A visually polished website with working navigation, pricing sections, FAQ — all functional, all professional. I’ve paid thousands of pounds for worse work on freelance platforms. The kind of output that local businesses currently purchase at premium rates.
I ran a parallel test requesting an “Ocean” themed website. Again, Minimax M3 produced something I found genuinely impressive — arguably more visually refined than my own site. The buttons worked. The redirects functioned. The pricing and contact sections rendered correctly.
Test 2: The Three-Way Game Build-Off
This is where I pushed all three models equally hard. Same prompt, same complexity, simultaneous execution.
The prompt: Create a playable HTML game similar to Mario. Catch falling gold coins, avoid bombs. Single HTML file. Start screen, scoreboard, three lives, modern design with animations, sound effects. When finished, create the file and open it so I can play immediately.
I ran Minimax M3 on the left, Claude Opus 4.8 in the center, and Codex 5.5 on the right. All received identical instructions. I pressed start simultaneously.
Claude finished first. The game loaded in browser. Space to start. The physics felt deliberately challenging — I found the platforming genuinely difficult, perhaps overly so. The controls responded, the character moved, but completing the level appeared nearly impossible in my attempts. Solid execution from a single prompt, but punishing difficulty.
Codex completed second. Simpler controls, more basic visual presentation. Functional but less ambitious. I could play it, the mechanics worked, but it felt like a minimum viable product compared to what I’d hoped for.
Minimax M3’s result surprised me most. Visually, it was clearly superior — the graphics, the polish, the overall presentation stood apart. It included lava hazards alongside the requested bombs and coins. The scoreboard functioned. Three lives displayed. Level progression worked. The spacebar controlled jumping. When I hit a bomb, I lost a life — the system logic operated correctly.
Playing it revealed intentional difficulty. The obstacles were dense, the timing tight. But the completeness of the package — sound effects, animations, visual design, functional game loop — from a single sentence prompt, without me writing a line of code?
I concluded that Minimax M3 produced the strongest visual result by a clear margin. The other two models created playable games, but Minimax M3’s output looked like something you’d consider for actual App Store release — with integrated Google Ads, potential for download revenue, the complete commercial pipeline.
What This Means for Online Business
I’ve been automating e-commerce operations for years. This feels different.
The agent framework means I can describe a person’s entire job — research trending products, compile lists, email reports, update inventory — schedule it, and the system executes daily without me. The human becomes the prompt writer and supervisor, not the doer.
I tested this specifically: I had the agent research currently trending products by country for eBay, generate the list, and email it to me. The entire workflow that previously required paid software subscriptions completed in approximately one minute, autonomously.
For my own trading operations, I can now deploy agents that work continuously, use the cheapest available tokens efficiently, and scale without linear labor costs. The Hermes Agent integration I configured optimizes this further — routing tasks to the most cost-effective model while maintaining quality.
Current Availability and Pricing
At launch, Minimax M3 is running a 50% promotional discount for 7 days. The per-million-token pricing sits in the cents range — I verified this against my own usage. The desktop agent has a free starting tier for testing.
The model weights are openly available. Someone without significant budget can run this on their own hardware. The barrier to entry for sophisticated AI automation has effectively disappeared.
FAQ
What exactly is Minimax M3?
Minimax M3 is an open-source large language model developed in China, released in June 2025. It features a 1 million token context window, multimodal capabilities (text, image, video, screen understanding), and a unique desktop agent application that can autonomously control a computer to perform tasks.
How does Minimax M3 compare to GPT-5.5 and Claude for coding?
On software testing benchmarks, Minimax M3 scored 79%, surpassing both GPT-5.5 and Claude 3.1 Pro. In my direct testing with identical game-building prompts, Minimax M3 produced more visually complete and polished results, though Claude finished faster and Codex produced simpler but functional output.
Is Minimax M3 actually free to use?
The model weights are open-source and free to self-host. The API pricing is significantly cheaper than competitors — per-million-token costs are in cents rather than dollars. There’s a free tier for testing the desktop agent, with paid tiers for higher usage. A 50% launch discount was active at time of testing.
Can Minimax M3 really replace human workers?
It can automate many repetitive computer-based tasks — research, data compilation, website building, code generation, report creation. However, it requires precise prompt engineering, clear boundary-setting, and human supervision. I view it as amplifying individual productivity rather than full replacement, though the economics of certain roles will shift dramatically.
Final Thoughts
I went into this test skeptical of the hype around another “GPT killer.” I finished it convinced that Minimax M3 represents something specific and valuable: the convergence of capable coding, genuine multimodal understanding, and autonomous action at a price point that removes financial barriers.
The desktop agent isn’t a demo. It’s a working tool I now have running scheduled tasks for my business. The website and game builds weren’t cherry-picked — they were first attempts with single prompts.
For entrepreneurs building online businesses, especially in e-commerce and automation, my recommendation is straightforward: test the free tier. Configure one agent with one specific task. Watch it work while you’re doing something else.
The first task I delegated was product research. I’m now deciding what to automate next.
