Introduction
DeepSeek has officially released the V4 Pro 0813 model. Instead of just focusing on parameters and benchmark scores, we will test its real programming capabilities with two practical projects.
Core Information of the New Model
- Maximum Output: 384K
- Thinking Mode: Supports both thinking and non-thinking modes, with thinking mode enabled by default
- Pricing: Approximately 3 times that of V4 Flash
- Benchmark Scores: The scores on the left side of the benchmark table are estimated scores, while the scores on the right side are accurate scores. The scores of V4 Pro 0813 are higher than those of V4 Flash 0731, but not exceeding Fable 5.
Project 1: Develop a Personal Blog with 6 Styles
The Prompt
Help me design and develop a modern personal blog website, providing 6 switchable visual styles:
- Minimalist black and white
- Tech future
- Warm retro
- Clear deep color
- Other styles you think are suitable
The website should include:
- Home page
- Article list
- Article details
- About us
- Contact information
Each style should have obvious differences in color, font and layout, and support both computer and mobile terminals. Add style switching buttons, light and dark modes and smooth transition animations.
Please use real example content and pictures, the interface is simple and designed, and finally deliver a complete project that can run directly.The Result
- Completion Time: 25 minutes
- Deliverables: A blog website with 6 visual styles, each supporting light and dark modes, equivalent to 12 display effects
- Functional Modules: Home page, article list, article details, about us, contact information and theme switching functions are all implemented
- Technical Indicators: No barrier 100, best practice 100, SEO 100, performance 72
Project 2: Generate a Runnable 3D Racing Game
The Prompt
Help me develop a runnable 3D racing game, including:
- Car control
- Track
- Opponent vehicles
- Timing ranking
- Collision effect
- Restart function
The picture should have a sense of speed, support keyboard control and computer browser operation, and finally deliver a complete runnable project.The Result
- Completion Time: 40 minutes
- Deliverables: A 3D racing game that can be run directly, including README documentation
- Functional Modules: Car control, track, opponent vehicles, timing ranking, collision, drift, sound effect and restart functions are all implemented
- Game Experience: The game can be run directly, but the visual effects such as the car model, mountains and clouds are not very realistic. The speed display is very real, and the wind effect is simulated when the car is running.
Conclusion
DeepSeek V4 Pro has a good project completion, but whether the price of nearly 3 times is worth it depends on whether you pay more attention to delivery capability or cost performance.
We will continue to test new models with the same set of real project acceptance methods in the future, not just looking at benchmarks, but directly seeing if it can deliver the project.
常见问题
What is DeepSeek V4 Pro 0813, and how is it different from V4 Flash?
V4 Pro 0813 is the newest DeepSeek release, positioned above V4 Flash in capability. It supports a 384K maximum output, has thinking mode enabled by default (with a non-thinking option), and costs roughly 3 times as much as V4 Flash. In benchmark scores it lands between V4 Flash 0731 and the top-tier Fable 5 — stronger than Flash but not the absolute ceiling. The real difference shows up in delivery: it handled both projects in this test — a 6-style blog in 25 minutes and a 3D racing game in 40 minutes — with solid functional completeness, which is the practical advantage Pro brings over Flash for full-project tasks.
Are these test projects actually runnable, or just mockups?
Both are fully runnable deliverables. The blog is a complete website with 6 switchable visual styles, each supporting light and dark modes for 12 total display effects, covering home, article list, article details, about, and contact pages with theme switching — scoring 100 on accessibility, best practices, and SEO. The 3D racing game runs directly in the browser with keyboard control, car physics, track, opponent vehicles, timing ranking, collisions, drifting, sound effects, and restart, plus README documentation. The visual polish of the game (car model, mountains, clouds) is noted as the weakest point, but everything works as delivered.
Is the ~3x price of V4 Pro worth paying over V4 Flash?
It depends on what you value. If you're optimizing for cost on high-volume or repetitive tasks, V4 Flash remains the better value. If you're building complete projects — a whole website or a full game from a single prompt — V4 Pro 0813 delivered both here without hand-holding, which is where the premium pays off. The practical guidance from this test: match the model to the task. Use Pro when delivery speed and completeness matter; use Flash when cost per token dominates your decision.
Should beginners use V4 Pro 0813?
Yes, for the reason this article demonstrates: you can write a plain-language prompt in natural language and get a complete, runnable project back without deep coding knowledge. The blog prompt in this test was a simple feature list, and the game prompt was six bullet points. That's an approachable entry point for beginners who want real output rather than studying theory. The main caveat is cost — at 3x Flash pricing, beginners iterating a lot may want to prototype on Flash first and reserve Pro for final project generation.
