Chat Models

Chat models are the core component for AI-powered conversations in VARIOS AI. They support text generation, document processing and optionally code execution.

Basic Data

Field	Required	Description
Image	No	Profile image for the model (displayed in the model selection)
Title	Yes	Display name of the model (e.g. “Azure GPT 5.2”)

API Configuration

Field	Required	Description
API	Yes	API type – see Available API Types below.
Credentials	Yes	Stored credentials for the selected provider (dropdown selection).
Model Name	Yes	Technical model name sent to the API (e.g. `gpt-5.2`, `claude-sonnet-4-5`).

Available API Types

API Type	Description
OpenAI Chat API (`/chat/completions`)	Standard OpenAI Chat Completions API for text generation
OpenAI Assistant API (`/assistants`)	OpenAI Assistant API for structured assistants
OpenAI Responses API (`/responses`)	OpenAI Responses API for specific response formats
IONOS API (`/chat/completions`)	IONOS-compatible Chat Completions API
OpenAI Chat API without HTTP Proxy	Direct connection without proxy support

Costs and Limits

Field	Required	Description
Cost in $ per million input tokens	No	Cost per one million input tokens above the context threshold.
Cost in $ per million output tokens	No	Cost per one million output tokens above the context threshold.
Cost in $ per million cache tokens	No	Cost per one million cache tokens above the context threshold.
Context Window	No	Maximum number of tokens that can be processed in the context of a request (e.g. 1050000).
Output Token Limit	No	Maximum number of tokens that a model may generate in a response (e.g. 128000).

If you want to avoid the higher costs of a pricing tier, choose a context window that is less than or equal to the configured threshold.

Behavior Settings

Field	Required	Description
Temperature	No	Controls creativity (0–2). Checkbox Use temperature must be enabled. Low = deterministic, high = creative.
Top P	No	Nucleus sampling parameter (0–1). Checkbox Use Top P must be enabled. Alternative to temperature control.
Additional Parameters	No	Additional API parameters as a JSON object. Enter valid JSON (e.g. `{}`). These parameters are appended directly to the API request.
Thinking Effort	No	Cognitive effort of the model. Checkbox Use thinking effort must be enabled. Value: Low, Medium or High.

Allow the model behavior settings to be overridden in order to tailor your assistants even more precisely to your needs. (Expert view required)

Streaming

Field	Required	Description
Supports Streaming	No	Checkbox Use a streaming model – Enables streaming responses (answer is displayed progressively).
Stream Options	No	Checkbox Use stream options – Enables extended streaming options (e.g. token usage in stream).

User Identification and MIME Types

Field	Required	Description
User Identification	No	Checkbox Use user identification – Adds a unique user identifier to the API request.
Allowed MIME Types	No	File types that are sent directly to the model (e.g. images for vision models). All other file types are automatically handled via document processing.

The Allowed MIME Types determine which files go directly to the model without being routed through document processing. Typical example: image/png, image/jpeg for vision models.

Check Service Status

Define whether test tokens should be sent to check the model’s availability and at what interval this should happen. Costs are incurred for each check.

DLP Security Settings

Basic DLP Settings

Detects personal data in the chat and encrypts it before transfer to the AI.

Option	Description
enabled	GDPR protection is always active and cannot be disabled by users.
optional	GDPR protection is active by default but can be disabled by users.
disabled	GDPR protection is disabled.

Sensitive File Protection

Blocks the upload of documents with confidential classification.

Option	Description
enabled	Upload of confidential documents is blocked.
disabled	Upload of confidential documents is allowed.

Enterprise DLP Settings

DLP Interface (ICAP)

Sends texts and files for review to the configured ICAP server.

Option	Description
enabled	ICAP server is used for all content.
disabled	ICAP server is not used.
