Power your apps with large-scale AI models
Take advantage of large-scale, generative AI models with deep understandings of language and code to enable new reasoning and comprehension capabilities for building cutting-edge applications. Apply these coding and language models to a variety of use cases, such as writing assistance, code generation, and reasoning over data. Detect and mitigate harmful use with built-in responsible AI and access enterprise-grade Azure security.
Large, pretrained AI models to unlock new scenarios
Custom AI models fine-tuned with your data and hyperparameters
Built-in features to help ensure you’re using AI responsibly
Enterprise-grade security with role-based access control (RBAC) and private networks
Deliver results for new AI use cases
Gain access to generative models that have been pretrained with trillions of words. Apply them to new scenarios including language, code, reasoning, inferencing, and comprehension.
Adapt AI models to your specifications
Customize generative models with labeled data for your specific scenario using a simple REST API. Fine-tune your model's hyperparameters to increase accuracy of outputs. Use the few-shot learning capability to provide the API with examples and achieve more relevant results.
Apply AI responsibly
Filter and moderate the content of your users' requests and responses to ensure that coding and language AI models are used responsibly, for their intended purpose.

Frequently asked questions about Azure OpenAI Service
Azure OpenAI Service is now generally available, but the service still currently requires registration, and Microsoft may limit access based on availability and eligibility criteria. Apply now.
Pricing is based on a pay-as-you-go consumption model with a price per unit for each model. See Azure OpenAI Service pricing.
There are several factors we’re using to evaluate and approve submitted use cases, which include, but aren’t limited to:
- Responsible use of the service—using the models as they’re intended to be used.
- Capacity—ensuring that we’re able to adequately onboard and provide service to customers.
The early-stage nature of the technology may result in unexpected and non-ideal behaviors. We limit access to the service to promote responsible use and limit the impact of high-risk use cases.
Azure OpenAI Service brings together OpenAI API and Azure enterprise-level security, compliance, and regional availability.
There are several ways that Microsoft is ensuring responsible use, including:
Tools and guidance: Azure OpenAI Service offers tools to empower customers with the ability to moderate generated content and guidance and implementation best practices to help customers design their applications, while keeping safety front and center.
Limited access: The service is currently available by limited access. This will ensure that early collaborations ensure the responsible AI safeguards are working in practice.
Azure OpenAI Service provides access to GPT-3, Codex, and Embeddings models. Dall·E 2 is available to invited customers. Learn more about the models.
We guarantee that Azure OpenAI Service will be available at least 99.9 percent of the time. See SLA details.
