3. DeepSeek V4 Core Technical Features

What makes DeepSeek V4 so anticipated stems from its bold innovations at the architectural level.

Engram Mixture of Experts Architecture (MoE 2.0)

DeepSeek V4 introduces the brand new Engram Architecture, an advanced version of the Mixture of Experts model (MoE 2.0).

• Plain Language Explanation: If traditional MoE is like having a group of experts take turns answering questions, then the Engram architecture gives these experts "shared memory," enabling more precise retrieval of needed knowledge fragments.
• Technical Breakthrough: Compared to V3's Multi-head Latent Attention (MLA), the Engram architecture further reduces memory usage while improving parameter utilization by 40%.
• Core Advantages:
  • 300% Faster Inference Decoding: Faster responses, lower latency.
  • Lossless Long Context: Maintains extremely high recall rates when processing ultra-long documents.

Superior Programming Capabilities

Programming ability is the signature strength of the DeepSeek series, and V4 pushes this advantage to the extreme.

• Benchmark Prediction: Expected to exceed 90% Pass@1 accuracy on HumanEval.
• Multi-language Support: Perfect support for 50+ programming languages including Python, JavaScript, C++, Rust, Go.
• Quality Comparison: Code generation quality is expected to surpass GPT-5 and Claude 4.5 Opus in complex logic generation and bug fixing tasks.

Multimodal Capability Upgrade

No longer limited to text, DeepSeek V4 also shows significant improvements in multimodal understanding.

• Image Understanding: Can precisely recognize UI design mockups and generate frontend code.
• Document Processing: Directly reads PDF/Word document tables and completes data analysis within seconds.

Enhanced Reasoning (Long CoT)

Introducing o1-like Long Chain of Thought (Long CoT) technology, enabling the model to perform deep "slow thinking" when answering math problems or complex logic questions, significantly improving accuracy.

4. Performance Benchmark Predictions

Based on V3's performance and leaked technical whitepaper data, we have the following predictions for V4:

Note: Parameter scale expected to remain around 671B MoE, but effective compute density significantly improved.

5. Open Source & Availability

Will DeepSeek V4 be open source?

The answer is yes. DeepSeek has always been a staunch supporter of the open-source community.

• Open Source Commitment: Officials have promised to continue open-sourcing V4's full weights and inference code.
• License: Expected to continue using permissive MIT or Apache 2.0 license, allowing commercial use.
• Local Deployment: With Engram architecture optimization, the quantized V4 model is expected to run smoothly on dual RTX 4090 or single A100, significantly lowering the barrier for local deployment.

6. API & Pricing

Price Prediction

DeepSeek has always been known as a "price killer."

• V3 Price: $0.14 / 1M tokens (input)
• V4 Prediction: API pricing expected to drop further or stay at V3 levels, with cost-effectiveness 10x+ better than GPT-4o.

7. Use Cases & Examples

• Software Development: Auto-generate unit tests, refactor legacy code, write complex SQL queries.
• Data Analysis: Upload CSV files, automatically generate visualization charts and analysis reports.
• Academic Research: Quickly summarize lengthy papers, assist in writing literature reviews.

8. FAQ

Q: How much stronger is V4 than V3? A: Overall capabilities expected to improve 30-40%, with qualitative leaps especially in long-context reasoning and mathematical logic.

Q: Does V4 support Chinese? A: As a domestic model, Chinese understanding and generation capabilities are deeply optimized, expected to outperform all foreign models in Chinese contexts.

Q: Can a regular computer run V4? A: The full version is difficult, but the community will definitely release 4bit/8bit quantized versions. High-end gaming PCs (64GB RAM + high VRAM GPU) may have a chance.

9. Summary

The release of DeepSeek V4 marks a new era for open-source large models where "performance and efficiency go hand in hand." Whether you're a developer, researcher, or business owner, V4 deserves 100% of your attention. Let's look forward to March together!
