The world of artificial intelligence is at a tipping point in mid-2026. On one side stands OpenAI with its ChatGPT, which has reached the incredible milestone of 1 billion monthly users. On the other hand, a new force is forming in China that doesn't play by Silicon Valley rules. The DeepSeek model has achieved something that American giants have long struggled with: providing top-tier capabilities at drastically lower operating costs.

Efficiency over Brute Force: Why DeepSeek Threatens Leaders?

It took a long time for the AI field to start talking about something other than the number of parameters. Most models, such as GPT-4 or Claude 3 Opus, rely on enormous computational resources and billions of dollars in hardware investments. DeepSeek, however, comes with a different approach. It uses advanced techniques, such as Mixture of Experts (MoE), which activate only the parts of the model needed for a given task. The result is a model that competes with the best American models in benchmark tests (e.g., MMLU or HumanEval), but its operating costs are orders of magnitude lower.

For both the average user and businesses, this means a fundamental change. While previous generations of AI required expensive subscriptions for access to "intelligence," DeepSeek democratizes the availability of advanced LLMs. If a company in the Czech Republic wants to implement AI into its processes, the price per token (units of text) for Chinese models can be much more manageable for the budget than for OpenAI.

Comparison of Main Market Players (Estimate as of July 2026)

Warning from Anthropic: When AI Starts Writing Itself

While the market focuses on price and users, the creators of the Claude model from Anthropic have issued warning signals. According to reports, Anthropic warns of the risk of recurrent self-improvement. This technology, where AI models start generating training data or code for their own successors, can lead to an exponential growth that humans will not be able to control.

A concrete example? By May 2026, the Claude model already generated over 80% of all code that Anthropic integrated into its codebase. This means that the development speed is not governed by human capacity, but by the capabilities of the algorithm. For the Czech technology scene, this presents a dual role: on one hand, a huge opportunity for software development automation in local companies, and on the other hand, the need for extreme caution when deploying autonomous systems.

Impact on the Czech and European Market

How do these global movements translate into reality in the Czech Republic? Several factors need to be considered:

• Availability and Czech language: Most of these models (ChatGPT, Claude, and DeepSeek) handle Czech very well, albeit with slightly different stylistic nuances. For Czech developers, it is crucial that models can be integrated via API into local applications without having to deal with a language barrier.
• Regulation (EU AI Act): The European Union is introducing strict rules for high-risk AI systems. While American models are already in the process of adapting to European standards, Chinese models like DeepSeek may face stricter scrutiny regarding data transparency and compliance with European values.
• Costs for local startups: For small Czech companies, the advent of low-cost models is an immense advantage. The ability to use top-tier AI at a fraction of the cost previously demanded by large corporations allows local players to scale their products much faster.

Summary for users: If you are looking for the best creative partner or analyst, Claude remains top-tier. If you need a versatile tool with a huge community, choose ChatGPT. However, if you are building your own application or looking for a way to significantly reduce automation costs, keep an eye on DeepSeek.
