Available Language Models

BusinessGPT currently supports models from ChatGPT (OpenAI) and Claude (Anthropic). This selection is based on the availability of EU-hosted models with relevant performance characteristics. Depending on your requirements, you can use different models for different tasks. Our portfolio is continuously expanded with new models from existing and additional providers.
The models differ in capabilities, speed, and cost. GPT-4o offers the most comprehensive capabilities for complex tasks, while models like GPT-4.1 Nano are faster and more cost-effective for simpler queries. Claude models excel in particularly nuanced text processing and longer context windows. Model selection should be made according to the respective task.

​
Special Features

BusinessGPT is distinguished by several core features: multi-model support, project-specific knowledge bases through document uploads, cross-team collaboration, and customizable assistants with user-defined instructions. Provider independence gives you full flexibility in model selection. Unlike public chatbots, your data is not used for training purposes and remains protected.
Unlike Microsoft Copilot, BusinessGPT is provider-independent and not limited to the Microsoft ecosystem. BusinessGPT also offers advanced features for collaborative knowledge management, flexible model selection, and customized AI assistants and can be used in a variety of use cases.

​
Functionality

Yes, the integrated search function searches the entire text content of uploaded documents using semantic search. Texts and objects in images can also be recognized and searched.
Yes, through the web search feature, BusinessGPT can find current information from the internet and include it in responses. The feature uses a secure API connection to common search engines and can be enabled or disabled as needed.
BusinessGPT provides sources with complete URLs so you can verify the information yourself. Source citations are automatically generated and based on the websites actually accessed during research.
Web research only accesses publicly available information and is dependent on its availability.
The quality of responses depends significantly on your inputs. Formulate precise questions, provide relevant context, and use the instructions feature for recurring tasks. For complex topics, you can upload relevant documents or reference specific knowledge bases. Using structured queries with clear role and format specifications leads to more consistent results.
Yes, all conversations are automatically saved and can be continued at any time. You can mark important chats, rename them, or organize them in knowledge bases. Chat history remains available according to configured retention policies.
Slash commands are shortcuts that start with a slash (/) and provide quick access to various functions:With search function:
  • /[search term] - Filters prompts by the specified term
Usage:
  1. Enter the slash command in the chat input field
  2. Select the desired prompt from the displayed list
  3. The selected prompt is automatically added to your chat
This feature enables efficient access to your prompt libraries directly while typing, without interrupting the conversation flow.

​
File Handling and Documents

BusinessGPT supports a wide range of file formats:Text Documents
  • PDF (.pdf)
  • Microsoft Word (.doc, .docx)
  • Text files (.txt)
  • Rich Text Format (.rtf)
  • Markdown (.md, .markdown)
Spreadsheets
  • Microsoft Excel (.xls, .xlsx)
  • CSV (.csv)

Yes, there are file size restrictions to ensure optimal performance:
  • Single file limit: 20MB per file
  • Total upload limit per session: 100MB
  • Storage limit: Depending on your subscription plan
For large documents that exceed these limits, we recommend:
  1. Splitting the document into smaller sections
  2. Compressing images within documents before uploading
  3. Converting to more efficient formats (e.g., from DOCX to PDF)
  4. Removing unnecessary elements like large images or embedded media
Attachments in BusinessGPT can be used in two ways:Direct Chat Attachments
  • Upload files directly in a chat session by clicking the attachment icon or dragging and dropping files
  • Files are processed immediately and available for that specific conversation
  • The AI can analyze the content of these files and reference them in its responses
  • Direct attachments are temporary and mainly intended for the current chat session
Permanent Attachments in Knowledge Bases
  • Files uploaded to knowledge bases are stored permanently (until deletion)
  • They can be accessed across multiple chat sessions
  • Multiple users can access these files if they have permission for the knowledge base
  • Knowledge base attachments are ideal for frequently referenced documents or collaborative work
All attachments are processed with OCR (Optical Character Recognition) for images and appropriate parsers for other file types to extract text content that the AI can work with.
Knowledge Folders (Knowledge Bases)
  • Permanent storage solution for documents
  • Structured organization with folders and subfolders
  • Searchable across entire content
  • Shareable with team members
  • Ideal for building a knowledge base over time
  • Content is indexed for semantic search
  • Can be referenced across multiple conversations
  • Permissions can be managed at folder level
Direct Attachments
  • Temporary use for immediate needs
  • Bound to a specific conversation
  • Not automatically shared with others
  • Ideal for one-time document analysis
  • No folder structure or organization
  • Not automatically saved for future reference
  • Easier to use for quick tasks
When to use what:
  • Use knowledge folders (knowledge bases) for documents you want to reference repeatedly or share with colleagues
  • Use direct attachments for quick, one-time document analyses or when privacy is a concern
You can always move a direct attachment to a knowledge base later if you decide it should be kept.

​
Common Issues

Solution: Formulate your query more precisely. If BusinessGPT repeatedly doesn’t deliver the desired results, look at the prompt examples.Tip: Use model selection. For complex topics, switching between ChatGPT and Claude can deliver better results.
Solution: Ask BusinessGPT to adjust the output length. (e.g., “Make the response shorter.” or “Explain this in more detail.”)Tip: Save preferred output formats as part of your instructions.
Solution: Verify critical information with external trusted sources or request source citations.Tip: Use the integrated web search for fact-checking and current information. Make your query more specific to get more precise answers. Additionally, you can access internal knowledge and include it in the chat or via knowledge bases.
Solution: Make sure the document is in a supported format and doesn’t exceed the maximum file size of 20MB.Tip: Split large documents into smaller, thematically related sections.
Tip: Link your queries with uploaded documents as a knowledge base.Tip: Add a part to your instructions such as: “Only answer if you are certain, or indicate if no reliable information is available on this topic.”
