Understand and Select Language Models (LLMs)

Behind Ayunis Core are so-called language models (also called LLMs – Large Language Models). These models generate the texts and responses you receive in chat. Here you’ll learn what you need to know about them.

What is a Language Model?

A language model is software trained on vast amounts of text. Through this training, it has learned how language is structured and can independently generate texts, answer questions, summarize content, or translate. The responses are generated word by word based on probabilities – the model “calculates” which word fits best next.

Important: AI is Not a Reference Book

Language models generate texts based on probabilities – not by looking things up in a database. Always check AI responses for accuracy before using them. Specifically, this means:

• Always verify facts – The AI can provide plausible-sounding but incorrect information
• No real-time knowledge – Without internet research enabled, the AI only knows its training data
• Same question, different answer – The AI can answer the same question differently

Available Models

Which language models are available to you is determined by your administrator. The default model for your organization is also set by the administrator. You can see the available models in the model selector in the chat input area. For each model, you can open a detailed info card with details on suitability, consumption, and hosting location.

Which Model Should I Choose?

When creating a chat, you can select a language model from the models enabled by your administrator.

Your Organization’s Default Model

Your administrator has set a default model for your organization. This model is automatically suggested when you start a new chat. It is suitable for most everyday tasks. You can set your own default model in your chat settings, which will override the organization setting for you.

Tip

If you’re unsure, simply use your organization’s default model. You can switch the model at any time during a chat if you’re not satisfied with the result.

Model Info Card

When selecting a model, you can hover over a model name to see a detailed info card. The card shows:

• Model description — a brief summary of what the model is best suited for
• Usage tier — how much of your allowance each message consumes (e.g., “Low usage”, “Medium usage”, “High usage”)
• Hosting location — where the model is hosted and by which provider, indicated by a country flag

This helps you make an informed choice, especially when weighing performance against consumption or when data residency matters.

Credit Consumption

Credit consumption is only relevant for customers on a usage-based plan with a credit allowance. Models with a higher usage tier consume more credits per message from your allowance.
