 # What is Azure OpenAI Service?
 
-Azure OpenAI Service provides REST API access to OpenAI's powerful language models including gpt-4.1, o3-mini, o1, o1-mini, GPT-4o, GPT-4o mini, GPT-4 Turbo with Vision, GPT-4, GPT-3.5-Turbo, and Embeddings model series. These models can be easily adapted to your specific task including but not limited to content generation, summarization, image understanding, semantic search, and natural language to code translation. Users can access the service through REST APIs, [Python/C#/JS/Java/Go SDKs](/azure/ai-services/openai/supported-languages).
