DeepSeek has officially released the production version of its V4 Pro AI model, bringing major improvements in coding, AI agents, tool use and long-running tasks. The new version, called DeepSeek-V4-Pro-0813, is now available through the DeepSeek app, website and API.
The launch is important because DeepSeek is moving beyond its earlier reputation for offering powerful models at very low prices. With V4 Pro, the company is putting more focus on AI agents that can complete tasks, rather than simply answering questions.
What Is DeepSeek V4 Pro?
DeepSeek V4 Pro is the company’s flagship model in the V4 family.
The model uses a Mixture-of-Experts (MoE) design with around 1.6 trillion total parameters and 49 billion active parameters. It also supports a 1 million-token context window, allowing it to work with very large documents and codebases.
The official version is now available across:
- DeepSeek app
- DeepSeek website
- DeepSeek API
- Developer tools
DeepSeek is keeping the API model name as deepseek-v4-pro, so developers using the previous version can access the newer model without changing the model name.
The Biggest Upgrade Is AI Agents
One of the main improvements in V4 Pro is its ability to work with AI agents.
An AI agent doesn’t simply answer a question. It can break a task into steps, use tools, work with files or code, and continue until the job is completed.
DeepSeek says the new V4 Pro has made large improvements in real-world agent tasks.
Its reported scores include:
- Terminal Bench 2.1: 87.9
- NL2Repo: 61.5
- CyberGym: 83.3
- DeepSWE: 62.7
- Toolathlon-Verified: 74.1
- AutomationBench: 31.8
These results show particularly strong improvements over the earlier V4 Pro preview. For example, DeepSWE reportedly increased from 12.8 to 62.7, while CyberGym increased from 52.7 to 83.3.
These are DeepSeek’s reported benchmark results, so they should be treated as company claims rather than independent proof that V4 Pro is the best model for every task.
Built for Coding
Coding is another major focus.
DeepSeek V4 Pro is designed to help developers with tasks such as:
- Writing code
- Finding bugs
- Understanding large codebases
- Fixing software problems
- Working with terminals
- Using development tools
- Building applications
The model can also work with very large codebases because of its 1 million-token context window.
That means developers can provide much more project information in a single session.
DeepSeek Adds OpenAI Responses API Support
Another important change is support for the OpenAI Responses API format.
DeepSeek says the API has been adapted specifically for coding workflows, including Codex.
The company also provides a setup process designed to make it easier for developers to connect V4 Pro with Codex-compatible tools.
This could make DeepSeek easier to use in existing AI development workflows.
Instead of building a completely new system around DeepSeek, developers can use familiar API patterns.
Developers Can Control How Much the AI Thinks
V4 Pro also gives developers more control over reasoning.
The model supports different thinking levels:
- Low — for simple tasks
- High — for normal work
- Max — for difficult problems
This can help developers balance speed, quality and cost.
For example, a simple request doesn’t need the same amount of reasoning as a difficult coding problem.
An AI agent could use lower reasoning for easy steps and switch to stronger reasoning when it faces a complex problem.
One Million Tokens of Context
Long context is another major feature of V4 Pro.
The model supports up to 1 million tokens, which can be useful for:
- Large software projects
- Long documents
- Research
- Large datasets
- Multi-file coding tasks
- Long AI-agent sessions
DeepSeek’s technical documentation says the V4 architecture is designed to make long-context processing more efficient by reducing the computing and memory needed to handle large amounts of information.
This could become increasingly important as AI agents move from short conversations to long-running tasks.
DeepSeek Is Changing Its Pricing
The V4 Pro launch also comes with an important pricing change.
DeepSeek has announced a new peak and off-peak pricing system for its API.
The new pricing is scheduled to take effect on August 17, 2026, according to Reuters.
Under the new peak pricing, V4 Pro will cost:
- $1.32 per million input tokens
- $3.96 per million output tokens
Off-peak pricing will be lower.
Even after the increase, DeepSeek remains relatively inexpensive compared with many competing frontier AI models.
The change is significant because DeepSeek became famous partly because of its extremely low AI costs.
The company now appears to be balancing stronger performance with the real cost of running large AI systems.
V4 Pro vs V4 Flash
DeepSeek also offers V4 Flash, which is designed to be faster and cheaper.
The basic difference is:
| Model | Main Focus |
|---|---|
| V4 Pro | Advanced reasoning, coding and agents |
| V4 Flash | Speed, efficiency and lower cost |
V4 Pro is therefore aimed at more difficult jobs, while Flash can be a better option when speed and cost are more important.
DeepSeek Is Moving Beyond Cheap AI
DeepSeek became globally famous after the release of its R1 reasoning model in 2025.
One reason it attracted so much attention was its ability to deliver strong performance at a much lower cost than many Western AI models.
V4 Pro shows a slightly different strategy.
The company is now focusing heavily on:
AI agents + coding + tool use + long context + efficiency
That is important because the AI market is changing.
The competition is no longer only about which model gives the best answer.
It is increasingly about which model can complete an entire task.
The Competition Is Getting Tougher
DeepSeek is competing against some of the biggest AI companies in the world.
OpenAI, Anthropic, Google and other companies are investing heavily in AI agents and coding systems.
DeepSeek’s advantage is its combination of:
- Open-weight models
- Large context windows
- Strong coding capabilities
- Agent support
- Relatively low prices
However, benchmark results vary between models and tasks.
For example, DeepSeek’s own comparison shows V4 Pro ahead of some competitors on certain agent benchmarks while trailing them on others.
So V4 Pro should not simply be described as the “best AI model.”
Its bigger strength may be its balance of capability, openness and cost.
Why This Release Matters
The launch comes at an important time for the AI industry.
Companies are increasingly building AI agents that can:
- Write software
- Browse the web
- Use tools
- Work with files
- Run commands
- Complete business tasks
These systems need models that can reason for longer periods and reliably use external tools.
DeepSeek is clearly trying to position V4 Pro for this new type of AI.
The Bigger Picture
DeepSeek V4 Pro is more than another model upgrade.
It shows how the AI competition is moving toward agentic AI.
The next generation of AI systems will not simply answer:
“How do I build this?”
They will increasingly be expected to:
“Build it for me.”
DeepSeek V4 Pro is designed for exactly this direction, with stronger coding, tool use, long-context support and agent capabilities.
The launch also shows that DeepSeek is trying to compete on more than price.
Its strategy is becoming:
Powerful AI + open technology + low cost + agents.
If V4 Pro performs well in real-world use, it could become a serious option for developers and companies building AI agents—especially those looking for an alternative to the leading closed AI models.
For the AI industry, the bigger takeaway is clear:
The race is moving from chatbots that answer questions to AI agents that actually get work done.
