Change AI Model

Change the underlying AI model powering your hellenicAI Assistants assistant, compare GPT, Claude, and Gemini behaviour, and apply the switch without disruption.

hellenicAI Assistants supports multiple AI models from different providers — including OpenAI (GPT), Anthropic (Claude), and Google (Gemini). You can switch models at any time from your dashboard without any downtime.

When to change the model

Different models have different strengths:

Model	Best for
GPT-4o	General-purpose tasks, strong reasoning, excellent Greek
Claude 3.5 Sonnet	Long documents, nuanced writing, analysis
Gemini 1.5 Pro	Large context windows, multimodal tasks
GPT-3.5 Turbo	Fast, low-cost replies for simpler questions

How to change your model

1. Log in to the dashboard

   Go to app.hellenicai.com and open your instance.

2. Find the model selector

   On the instance page, look for the Model setting. It is usually shown in the Settings or Configuration section.

3. Select a new model

   Click the dropdown and select the model you want to use.

4. Save your changes

   Click Save. The change takes effect immediately — your next message will use the new model.

Model pricing varies. More capable models (like GPT-4o and Claude 3.5 Sonnet) use more tokens and will increase your monthly usage costs. Check the Usage tab to monitor spending.

Testing the new model

After switching, use the built-in Chat widget to send a few test messages and confirm the responses meet your expectations. If not, you can switch back to your previous model at any time.
