Ready to help with your development tasks

V4
Hi! I'm DeepSeek V4.
I can help you with complex coding tasks, analyze large codebases, review documentation, and more. Try asking me about refactoring legacy code, debugging multi-file dependencies, or explaining technical concepts.

The Challenge

Modern codebases don't fit in small context windows

You need an AI that can reason across files, tests, and docs—not just autocomplete.

The Promise

Built to push the boundaries

DeepSeek V4 is expected to push coding performance and long-context handling to a new level.


What is DeepSeek V4?

DeepSeek's next-generation flagship foundation model, focused on complex tasksespecially software development. Now available for early access on our platform.

Massive Context
Entire codebases, multi-document analysis
High Stakes
Production systems, architectural decisions
Accuracy > Pleasantness
Reliable analysis, not encouraging words

Core Capabilities

Capability 01

Advanced Code Generation & Understanding

DeepSeek V4 outperforms GPT and Claude on coding tasks in early internal testing.

Code Quality 95%

Complex Frameworks

Multi-step logic across files

Legacy Refactoring

Modernize outdated patterns safely

Production-Grade

Real code, not just demos

Capability 02

Massive Long-Context Processing

One of the most groundbreaking features of DeepSeek V4 is its reported ability to handle context windows in the millions of tokens—a significant breakthrough compared to typical models that handle hundreds of thousands at most.

What does this mean in practice?

  • Process entire repositories without chunking or summarization
  • Read complete technical specifications alongside implementation code
  • Maintain consistency across hundreds of pages of documentation
  • Avoid “context loss”—the frustrating moment when an AI “forgets” what you told it earlier

This isn't a gimmick. For engineers analyzing large systems, researchers working with extensive documentation, or teams trying to understand multi-module platforms, this capability is transformative.

Capability 03

Next-Generation Architecture

Built from the ground up for engineering reliability — architectural upgrades and targeted optimizations for development workflows.

Common Misconceptions & FAQ

Is DeepSeek V4 available now?

Yes! Available now exclusively on our platform. Early access ahead of general launch.

Will DeepSeek V4 replace GPT or Claude?

No. It's designed to complement them. Think of it as part of a multi-model toolkit where each AI serves different purposes.

Is DeepSeek V4 only for Chinese developers?

No. Core capabilities are valuable globally, with strong support for Chinese contexts.

Can I run DeepSeek V4 locally?

This depends on whether DeepSeek releases open model weights. Official deployment options will be clarified at launch.

What if DeepSeek V4 gives me wrong information?

DeepSeek V4 is assistive, not autonomous. Always review outputs. Structured reasoning makes errors easier to verify.

Is DeepSeek V4 better than GPT-4 or Claude?

“Better” depends on the task. For engineering-heavy, context-intensive, complexity-driven work, early reports suggest DeepSeek V4 may outperform them. For general conversation, creative writing, or teaching, GPT and Claude may remain superior.
