DeepSeek V4 Bewertung

In this era where AI models are increasingly being used for autonomy, the majority of businesses, from enterprises to individual users, have integrated AI models into their workflows. However, the high demand for AI has caused popular and advanced LLM providers like ChatGPT and Anthropic to increase their prices. In today's AI age, the cost of using an LLM to automate your workflow has increased significantly. However, there are also large-scale language models that offer similar performance to popular AI models but at much lower prices, and DeepSeek V4 is one of them. 

In this article, we will explore the features and capabilities of the DeepSeek V4 model.

TL; DR

DeepSeek V4 is the Chinese AI lab’s 2026 open-source flagship, delivering performance close to GPT-5.5 and Claude Opus 4.7 at significantly lower cost. It comes in three variants—Preview (1M context, open-source), Pro (1.6T total / 49B active parameters), and Flash (248B total / 13B active parameters)—with API pricing as low as $0.14/$0.28 per million input/output tokens for Flash and $1.74/$3.48 for Pro. It scores strongly in coding and reasoning benchmarks, though its 66K output token limit is half that of GPT-5.5 despite matching its 1M input context window. Access is available via DeepSeek’s chatbot or API; for EU-hosted, GDPR-compliant deployment, TextCortex offers an alternative infrastructure.

What is DeepSeek V4?

DeepSeek V4 is the latest open-source large-language model of the Chinese AI Lab DeepSeek, released in 2026. While DeepSeek V4's selfie features and performance rival those of DeepSeek V3 GPT-4, it boasts capabilities comparable to GPT-5.5 and Claude Opus 4.7. DeepSeek V4 joins the competition between Claude Opus 4.7 and GPT-5.5, offering users a new option. Furthermore, the API pricing for this option is significantly lower than the other two models.

DeepSeek V4 Model Family

DeepSeek V4 offers users three different sub-models: DeepSeek V4 Preview, DeepSeek V4 Pro, and DeepSeek V4 Flash. DeepSeek V4 Preview offers 1 million context windows and is open-source. DeepSeek V4 Pro offers 1.6T total parameters and 49B active parameters, ideal for long-term and complex tasks. DeepSeek V4 Flash, on the other hand, offers 248B total parameters and 13B active parameters, providing users with a faster experience.

How to Access DeepSeek V4?

There are two main ways to access the DeepSeek V4 model. The first is to use it as an AI chatbot through DeepSeek. To use the DeepSeek V4 model, simply head to the official DeepSeek website and create an account. Since the DeepSeek AI chatbot's interface is almost identical to ChatGPT, you shouldn't experience any unfamiliarity or difficulty using it.

Another way to use the DeepSeek V4 model is to use it as an API. However, if you want to use DeepSeek V4 as an API, American or Chinese providers come to the forefront. If you want to use DeepSeek V4 compliant with the EU AI Act and GDPR requirements in Europe, TextCortex is the solution for you. With TextCortex, you can use the DeepSeek V4 model both as an API and as an AI agent in an EU-hosted environment.

DeepSeek Preise

DeepSeek offers performance comparable to the GPT-5.5 and Claude Opus 4.7 models while providing significantly more affordable pricing. The DeepSeek Flash model charges $0.14 per million input tokens and $0.28 per million output tokens. The DeepSeek Pro model charges $1.74 per million input tokens and $3.48 per million output tokens.

DeepSeek V4 Features and Capabilities

DeepSeek V4 is a GPT-5.5 and Opus 4.7 alternative that offers high performance at a low price. Let's take a closer look at the performance and features of DeepSeek V4.

Coding and Agentic Performance

DeepSeek V4 achieves high scores in the SWE-verified, Terminal Bench 2.0, and Toolathlon benchmarks, which are used to measure the coding and agentic performance of LLMs. It has a score of 80.6% in the SWE-verified benchmark and 67.9% in Terminal Bench 2.0. These scores are just behind the GPT-5.5 and Opus 4.7 models and higher than those of the GPT-5.4 and Opus 4.6 models.

Begründung

Another area where DeepSeek V4 excels is in reasoning tasks. The DeepSeek V4 model achieves a score of 90.1% on the GPQA benchmark, used to measure scientific reasoning in LLMs. The GPT-5.5 model scores 93.6% on the same benchmark. DeepSeek V4 comes just behind GPT-5.5 on the Humanity's Last Exam benchmark with a score of 48.2%.

Kontext-Fenster

DeepSeek V4, with its 1 million input tokens context window, is not behind its competitors GPT-5.5 and Opus 4.7. However, the disadvantage of DeepSeek V4 is that it only offers 66K output tokens. This number of tokens is equal to half the output token limit of GPT-5.5. In other words, although DeepSeek V4 can analyze longer inputs, it cannot generate long outputs in one go.

TextCortex AI: Leverage DeepSeek V4 as GDPR-Compliant

If you want to integrate the DeepSeek V4 model into your enterprise as an EU-hosted solution and automate your workflow, TextCortex is the solution for you. TextCortex allows you to access DeepSeek V4 as an AI agent and API for your enterprise or personal use. With TextCortex, you can automate your workflow by building AI agents powered by the DeepSeek V4 model, or you can use it as an EU-hosted and GDPR-compliant API.

Build DeepSeek V4-Powered AI Agents

With the TextCortex AI agent builder, you can build AI agents that use the DeepSeek V4 model as the default LLM and use it to automate specific tasks. The fact that DeepSeek V4 offers similar performance to GPT-5.5 and Claude Opus 4.7 models while being much more affordable is a good reason to integrate DeepSeek V4 into your enterprise workflow. TextCortex takes things a step further by offering DeepSeek V4 as an EU-hosted version, ensuring compliance with the EU AI Act and GDPR regulations.

Access DeepSeek V4 as API in EU
