 API keys from the following providers are supported:
 
 * Anthropic
+* AWS Bedrock
+* Google AI Studio
 * Microsoft Foundry
 * OpenAI
+* OpenAI-compatible providers
 * xAI
 
 Fine-tuned models are also supported, but functionality and quality of results can vary depending on the fine-tuning setup. You should test your model and review its outputs carefully before using it in production.
