Overview
Azure OpenAI Service provides enterprise customers with access to OpenAI's powerful language models (GPT-4o, GPT-4o-mini, GPT-3.5 Turbo) through Microsoft's trusted cloud infrastructure. With Bolna's Azure OpenAI integration, you can build voice agents that can leverage enterprise grade AI with an enhanced compliance, data residency guarantees, and Microsoft's enterprise SLAs.
Azure OpenAI is ideal for the regulated industries and enterprises that require enhanced security, compliance certifications (SOC 2, HIPAA, ISO 27001), and data residency controls while maintaining the same AI capabilities as OpenAI's models.
