Azure Direct Models
Direct from Azure models are a select portfolio curated for their market-differentiated capabilities:- Secure and managed by Microsoft: Purchase and manage models directly through Azure with a single license, consistent support, and no third-party dependencies, backed by Azure's enterprise-grade infrastructure.
- Streamlined operations: Benefit from unified billing, governance, and seamless PTU portability across models hosted on Azure - all as part of one Azure AI Foundry platform.
- Future-ready flexibility: Access the latest models as they become available, and easily test, deploy, or switch between them within Azure AI Foundry; reducing integration effort.
- Cost control and optimization: Scale on demand with pay-as-you-go flexibility or reserve PTUs for predictable performance and savings.
Key capabilities
About this model
The o1 series models are specifically designed to tackle reasoning and problem-solving tasks with increased focus and capability. These models spend more time processing and understanding the user's request, making them exceptionally strong in areas like science, coding, math and similar fields.Key model capabilities
- o1 adds advanced image analysis capabilities with the new version. Enhance your prompts and context with images for additional insights.
- Complex Code Generation: Capable of generating algorithms and handling advanced coding tasks to support developers.
- Advanced Problem Solving: Ideal for comprehensive brainstorming sessions and addressing multifaceted challenges.
- Complex Document Comparison: Perfect for analyzing contracts, case files, or legal documents to identify subtle differences.
- Instruction Following and Workflow Management: Particularly effective for managing workflows requiring shorter contexts.
- Developer message replaces system message
- Reasoning effort as in
high,medium, andlow. It controls whether the model thinks "less" or "more" in terms of applying cognitive reasoning. - Vision input, structured outputs, and tools.
o4-mini: The most efficient reasoning model in the o model series, well suited for agentic solutions. Now generally available.o3: The most capable reasoning model in the o model series, and the first one to offer full tools support for agentic solutions. Now generally available.o3-mini: A faster and more cost-efficient option in the o3 series, ideal for coding tasks requiring speed and lower resource consumption.o1: The most capable model in the o1 series, offering enhanced reasoning abilities. Now generally available.o1-mini: A faster and more cost-efficient option in the o1 series, ideal for coding tasks requiring speed and lower resource consumption.
Use cases
See Responsible AI for additional considerations for responsible use.Key use cases
For example, o1 can be used by healthcare researchers to annotate cell sequencing data, by physicists to generate complicated mathematical formulas needed for quantum optics, and by developers in all fields to build and execute multi-step workflows.Out of scope use cases
o1 model does not include all the features available in other models. OpenAI has incorporated additional safety measures into the o1 models, including new techniques to help the models refuse unsafe requests. These advancements make the o1 series some of the most robust models available. OpenAI measures safety is by testing how well models continue to follow its safety rules if a user tries to bypass them (known as "jailbreaking"). In OpenAI's internal tests, GPT-4o scored 22 (on a scale of 0-100) while o1-preview model scored 84. You can read more about this in the OpenAI's system card and research post .Pricing
