 - Since September 2024: Experiments have been started on how we can work on long texts with AI Studio. Let's say you want to write a fantasy novel or create a complex project proposal and use LLM for support. The initial experiments were promising, but not yet satisfactory. We are testing further approaches until a satisfactory solution is found. The current state of our experiment is available as an experimental preview feature through your app configuration.

 **Key advantages:**
 - **Free of charge**: The app is free to use, both for personal and commercial purposes.
- **Independence**: You are not tied to any single provider. Instead, you can choose the provider that best suits their needs. Right now, we support OpenAI (GPT4o, o1, etc.), Mistral, Anthropic (Claude), Google Gemini, xAI (Grok), and self-hosted models using [llama.cpp](https://github.com/ggerganov/llama.cpp), [ollama](https://github.com/ollama/ollama), [LM Studio](https://lmstudio.ai/), [Groq](https://groq.com/), or [Fireworks](https://fireworks.ai/).
+- **Independence**: You are not tied to any single provider. Instead, you can choose the provider that best suits their needs. Right now, we support OpenAI (GPT4o, o1, etc.), Mistral, Anthropic (Claude), Google Gemini, xAI (Grok), DeepSeek, and self-hosted models using [llama.cpp](https://github.com/ggerganov/llama.cpp), [ollama](https://github.com/ollama/ollama), [LM Studio](https://lmstudio.ai/), [Groq](https://groq.com/), or [Fireworks](https://fireworks.ai/). For scientists and employees of research institutions, we also support [Helmholtz](https://helmholtz.cloud/services/?serviceID=d7d5c597-a2f6-4bd1-b71e-4d6499d98570) and [GWDG](https://gwdg.de/services/application-services/ai-services/) AI services. These are available through federated logins like eduGAIN to all 18 Helmholtz Centers, the Max Planck Society, most German, and many international universities.
 - **Assistants**: You just want to quickly translate a text? AI Studio has so-called assistants for such and other tasks. No prompting is necessary when working with these assistants.
 - **Unrestricted usage**: Unlike services like ChatGPT, which impose limits after intensive use, MindWork AI Studio offers unlimited usage through the providers API.
 - **Cost-effective**: You only pay for what you use, which can be cheaper than monthly subscription services like ChatGPT Plus, especially if used infrequently. But beware, here be dragons: For extremely intensive usage, the API costs can be significantly higher. Unfortunately, providers currently do not offer a way to display current costs in the app. Therefore, check your account with the respective provider to see how your costs are developing. When available, use prepaid and set a cost limit.

+

    AI Studio can save the generated code to the file system. You can select a base folder for this. AI Studio ensures that no files are created

    When you rebuild / re-generate the ERI server code, AI Studio proceeds as follows: All files generated last time will be deleted. All
    other files you have created remain. Then, the AI generates the new files. <b>But beware:</b> It may happen that the AI generates a
    file this time that you manually created last time. In this case, your manually created file will then be overwritten. Therefore,
    you should always create a Git repository and commit or revert all changes before using this assistant. With a diff visualization,
    you can immediately see where the AI has made changes. It is best to use an IDE suitable for your selected language for this purpose.
