DeepSeek-V4 Source Code Leaked on GitHub: The Chinese AI That 'Bypasses Nvidia Chips' and Lit Wall Street on Fire (MODEL1 Architecture Analysis)

At 4:00 AM Shenzhen time, a new repository was made public on GitHub that might just contain the most consequential lines of code of the decade. While the world was still reeling from the power of the R1 model, the DeepSeek AI laboratory inadvertently (or perhaps entirely intentionally) leaked their fourth-generation "flagship killer": DeepSeek-V4.

But this isn't just a simple software update. The leaked code exposes a completely new architecture named "MODEL1". An architecture that makes a terrifying and disruptive claim: "To achieve Artificial General Intelligence (AGI), we do not need $100 billion data centers or thousands of Nvidia H100 chips."

This statement is a technical challenge for Sam Altman (OpenAI), but for Jensen Huang (Nvidia CEO), it is a commercial nightmare. If the claims behind MODEL1 are true, the trillion-dollar hardware bubble may have just burst this morning.
I, Inspector Gemini, have analyzed the Python code leaked in this repository line-by-line to understand exactly how this Chinese "black magic" works. Can you really defeat Silicon Valley giants with a home graphics card? Let's dive deep into the code. 👇

1. Crime Scene Investigation: The "DeepSeek-V4-Open" GitHub Leak

The story began with a simple Commit. A user with the handle "HighDimensionalCat" published a repository this morning containing lightweight weights and custom CUDA kernels for the DeepSeek-V4 model. In less than 3 hours, the repo garnered over 40,000 Stars on GitHub, and the rush of users cloning the repository essentially DDoS'd Microsoft's servers for a few moments.

What exactly was leaked?
Unlike previous models where only the "final output" or API was available, the technical documentation reveals that DeepSeek has fundamentally changed how the model is trained. The config.json files in the repo show that this model was trained not on a cluster of 10,000 H100s, but on a much smaller cluster of older chips (likely A800s). The message is clear: The Chinese engineers have found a way to bypass hardware limitations through superior software engineering.

2. What is MODEL1? Saying Goodbye to Traditional Transformers

The most critical part of this news is the unveiling of the MODEL1 architecture. Until today, every major model (from GPT-4 to Claude 3) was built on the standard "Transformer" architecture, which is notoriously power-hungry and has an insatiable appetite for RAM (VRAM). MODEL1 changes the rules of engagement.

🔬 Technical Autopsy: MLA and MoE on Steroids!

According to the leaked docs, MODEL1 rests on two pillars never before seen in Western models:
1. Multi-Head Latent Attention (MLA): In normal models, the memory (KV Cache) fills up rapidly as the text gets longer. This is the Achilles' heel of current LLMs. MLA compresses this memory into a latent vector form. The result? V4 can read and analyze 1,000-page books while occupying only 5% of the RAM required by rival models like Llama 3.
2. Ultra-Granular MoE: The "Mixture of Experts" (MoE) technique isn't new, but DeepSeek has taken it to a granular extreme. Instead of having 8 large experts, they chopped the model into 256 tiny experts. For every word generated, only 2 or 3 specific experts are activated. This means you have a "massive" model that behaves like a "tiny" model during inference, sipping electricity rather than gulping it.

3. Magic Optimization: Running a 600B Parameter Model on an RTX 5090?

This is where gamers, developers, and home users should get excited. Until yesterday, running a powerful AI model (at the GPT-4 level) required enterprise servers with 8x A100 GPUs, costing upwards of $250,000. This meant top-tier AI was the exclusive monopoly of mega-corporations.
But DeepSeek-V4 with MODEL1 makes a bold claim: It runs on a high-end consumer desktop.

Developers who have already tested the leaked code report that the "Quantized" (4-bit compressed) version of this model runs at incredible speeds on a single NVIDIA RTX 5090 (with 32GB VRAM).
What does this mean?
It means the reasoning power that was locked behind trillion-dollar company gates can now run locally on your PC in your bedroom. No internet required, no $20 monthly subscription, and no sending your sensitive data to American servers for analysis.

4. Battle of the Numbers: DeepSeek-V4 vs. US Giants

Let's skip the marketing fluff and put the numbers on the table. The claim of "bypassing Nvidia" is bold, but does it hold up in benchmarks? The table below compares the technical specs of the leaked DeepSeek-V4 against GPT-4 Turbo and Claude 3.5 Sonnet. These figures are extracted directly from the GitHub technical documentation.

As you can see, DeepSeek's strength lies not in "raw brute force," but in Efficiency. This model was trained at one-tenth the cost of GPT-4 and can run on hardware that is 100 times cheaper than Microsoft's servers. This is the exact reason Nvidia shareholders are panicking: When you can reach the destination in a Toyota Corolla, why buy a Ferrari?

5. Practical Guide: How to Run DeepSeek-V4 on Your PC Right Now

Many of you asked in the comments, "Can I really run this on my own rig?" The short answer is YES, but there are conditions. Based on the Tekingame technical team's testing of the leaked kernels, here are the minimum requirements for the optimized (Quantized) version:

• 🖥️ Minimum Hardware: NVIDIA RTX 3090, 4090, or 5090 (with 24GB+ VRAM). For better token generation speed, 32GB of System RAM (DDR5) is highly recommended.
• 🛠️ Software Tools: You need to install Ollama or LM Studio. These tools have just updated to support MODEL1 kernels.

Steps to Run (Simplified):
1. Open your Terminal (CMD).
2. If you have Ollama installed, type the following command (note: this pulls the 4-bit version):
ollama run deepseek-v4:quant-4bit
3. Wait for the 14GB file to download.
4. Done! You now have a GPT-4 class AI running completely offline. You can unplug your internet cable and ask it to write Python code or compose poetry.

6. Market Reaction: Why is Wall Street Terrified of DeepSeek?

Immediately after the news went viral on X (formerly Twitter), the stock market reacted violently. Nvidia (NVDA) shares plummeted 12% in pre-market trading. Other hardware manufacturers like AMD and TSMC also bled red. This emotional reaction highlights just how heavily investors were betting on Nvidia's "monopoly."

What is the logic behind the fear?
Nvidia's business model relies on the assumption that AI models will get "bigger" and "heavier" every year, forcing companies to buy more expensive chips.
DeepSeek-V4 proved that by "optimizing software," you can drastically reduce hardware requirements.
A senior analyst at Morgan Stanley wrote: "If Google and Microsoft can cut their data center costs by 50% using DeepSeek-like architectures, Nvidia's revenue in 2027 could contract by 40%. This isn't a price correction; it's a paradigm shift."

7. The Chip War: When US Sanctions Backfire

The irony is palpable: The United States sanctioned the export of advanced chips to China to stifle the country's AI progress.
But history proves that "restriction is the mother of invention."

Because Chinese engineers didn't have access to infinite H100s, they were forced to optimize their code to the absolute limit to run on older chips. The result? They now possess the world's most efficient AI architecture. Meanwhile, American companies—swimming in an abundance of chips—became lazy and built inefficient, power-hungry models.
Now, the US faces a strange paradox: America has the superior hardware, but the superior software architecture (MODEL1) has come from China.

8. The Future: Democratization of AI or a Digital Cold War?

The leak of DeepSeek-V4 isn't just a technical news story; it's a historical turning point. Until today, it was assumed that the gap between Chinese and American models (like GPT-5) was at least 2 years. Initial V4 benchmarks show that this gap has closed to "zero."
