Hi Bettina Weinmann , I'll try help you as best I can, although I haven't setup this up in Azure, there is a lot of documentation around this from MS to help create minimal walk-through underneath.

Recommended models (balance of quality/speed/cost)

• Default for testing and most production: gpt-4o-mini (OpenAI or Azure OpenAI). Lowest cost, very fast, strong translation quality.
• When quality really matters: gpt-4o. Better handling of nuance/formatting; higher cost and slightly slower.
• Not recommended for MT: o1/o3 (reasoning-focused, slow/expensive) and 3.5 family (older, weaker quality/formatting).

Quick Azure OpenAI setup (minimal-cost)

1. Access and subscription
   • Ensure your Azure subscription has Azure OpenAI enabled (https://aka.ms/oai/access).
2. Create the resource
   • Azure Portal > Create resource > Azure AI Services > Azure OpenAI.
   • Choose an EU region that has your target model (often West Europe or North Europe; Germany regions may not have all models).
3. Deploy a model
   • Go to Azure AI Foundry (https://ai.azure.com) or the resource in the Portal.
   • Create a Deployment for gpt-4o-mini (or gpt-4o). Give it a short deployment name, e.g., gpt4o-mini.
4. Get connection details
   • From the Azure OpenAI resource: copy Endpoint (looks like https://YOURRESOURCE.openai.azure.com), and one of the Keys.
   • Note the API version your deployment supports (for chat/completions; a recent 2024 date is fine).

Configure the OpenAI Provider in Studio 2024

• Install the OpenAI Provider from the RWS AppStore.
• Studio > Project Settings > Language Pairs > Translation Memory and Automated Translation > Add > OpenAI Provider.
• Choose a backend:
  • OpenAI API: paste your OpenAI API key; Base URL https://api.openai.com/v1; Model gpt-4o-mini or gpt-4o.
  • Azure OpenAI: select Azure; paste Endpoint (root URL only), API key, Deployment name (the one you created), and API version.
• Suggested settings for translation:
  • Temperature: 0.0–0.2 for consistent, non-creative output.
  • Ensure “chat/completions” is used.
• Put the provider near the top of your MT list so it’s queried during interactive translation and pre-translate.
