Hi @Learn_Jerin

Thanks for asking this important question. If you're planning to summarize business-sensitive data such as customer names, addresses, dates of birth, or other personally identifiable information (PII), Azure OpenAI Service is generally the recommended option over consumer AI services because it is designed with enterprise security, privacy, and compliance in mind.

A few key points:

• Your prompts and completions are not used to train or improve Microsoft's foundation models. Data submitted through Azure OpenAI remains under your control and is processed according to Microsoft's enterprise data handling commitments.
• Data is encrypted in transit and at rest, and access is governed through Microsoft Entra ID, Azure RBAC, virtual network/private endpoint support, and other Azure security controls.
• For highly sensitive workloads, consider implementing data minimization by masking or pseudonymizing PII before sending it to the model, unless the complete information is required for the summarization task.
• You can further strengthen security by integrating Azure AI Content Safety, Microsoft Purview, Azure Key Vault, and Private Link to meet your organization's governance and compliance requirements.

Regarding your other questions:

• Free subscription: You can create an Azure account with free credits, but Azure OpenAI Service is not a permanently free service. Access requires an approved Azure OpenAI resource, and usage is billed based on the deployed model and the number of input/output tokens processed.
• Token limits: Token limits vary by model (for example, GPT-4.1, GPT-4o, GPT-4.1-mini, GPT-4o-mini, etc.). The current context window, rate limits, and pricing are documented by Microsoft and may differ depending on the model and your quota allocation.

If your data includes regulated information (such as healthcare, financial, or government records), it's also worth reviewing your organization's compliance requirements before deployment.
