For customers focused on low costs, small compute footprints, and edge compatibility, Phi-3 SLM fine-tuning is proving to be a valuable approach. Khan Academy recently published a research paper showing their fine-tuned version of Phi-3 performed better at finding and fixing student math mistakes compared to other models.

A platform for customization quality 

Fine-tuning is about so much more than just training models. From data generation to model evaluation, and support for scaling your custom models to production workloads, Azure provides a unified platform: data generation via powerful LLMs, AI Studio Evaluation, built in safety guardrails for fine-tuned models, and more. As part of our GPT-4o and 4o-mini now generally available, we’ve recently shared an end-to-end distillation flow for retrieval augmented fine-tuning, showing how to leverage Azure AI for custom, domain-adapted models.

We are hosting a webinar on October 17, 2024, to unpack the essentials and practical recipes to get started with fine-tuning. We hope you will join us to learn more.

Expanding model choice

With over 1,600 models, Azure AI model catalog offers the broadest selection of models to build generative AI applications. Azure AI models are now also available through GitHub Models so developers can quickly prototype and evaluate the best model for their use case.

I am excited to share new model availability, including: 

• Phi-3.5-MoE-instruct, a Mixture-of-Experts (MoE) model and Phi-3.5-vision-instruct through serverless endpoint and also through GitHub Models. Phi-3.5-MoE-instruct, with 16 experts and 6.6B active parameters provides multi-lingual capability, competitive performance, and robust safety measures. Phi-3.5-vision-instruct (4.2B parameters), now available through managed compute enables reasoning across multiple input images, opening up new possibilities such as detecting differences between images.
• Meta’s Llama 3.2 11B Vision Instruct and Llama 3.2 90B Vision Instruct. These models are Llama’s first ever multi-modal models and are available via managed compute in the Azure AI model catalog. Inferencing through serverless endpoints is coming soon. 
• SDAIA’s ALLaM-2-7B. This new model is designed to facilitate natural language understanding in both Arabic and English. With 7 billion parameters, ALLaM-2-7B aims to serve as a critical tool for industries requiring advanced language processing capabilities.

Achieve AI transformation with confidence

Earlier this week, we unveiled Trustworthy AI, a set of commitments and capabilities to help build AI that is secure, safe, and private. Data privacy and security, core pillars of Trustworthy AI, are foundational to designing and implementing new solutions. To help meet regulatory and compliance standards, Azure OpenAI Service—an Azure service, provides robust enterprise controls so organization can build with confidence. We continue to invest to expand enterprise controls and recently announced upcoming availability of Azure OpenAI Data Zones to further enhance data privacy and security capabilities. With the new Data Zones feature that builds on the existing strength of Azure OpenAI Service’s data processing and storage options, Azure OpenAI Service now provides customers with options between Global, Data Zone, and regional deployments, allowing customers to store data at rest within the Azure chosen region of their resource. We are excited to bring this to customers soon.

Additionally, we recently announced full network isolation in Azure AI Studio, with private endpoints to storage, Azure AI Search, Azure AI services, and Azure OpenAI Service supported via managed virtual network (VNET). Developers can also chat with their enterprise data securely using private endpoints in the chat playground. Network isolation prevents entities outside the private network from accessing its resources. For additional control, customers can now enable Entra ID for credential-less access to Azure AI Search, Azure AI services, and Azure OpenAI Service connections in Azure AI Studio. These security capabilities are critical for enterprise customers, particularly those in regulated industries using sensitive data for model fine-tuning or retrieval augmented generation (RAG) workflows.

In addition to privacy and security, safety is top of mind. As part of our responsible AI commitment, we launched Azure AI Content Safety in 2023 to enable generative AI guardrail. Building on this work, Azure AI Content Safety features—including prompt shields and protected material detection—are on by default and available at no cost in Azure OpenAI Service. Further, these capabilities can be leveraged as content filters with any foundation model included in our model catalog, including Phi-3, Llama, and Cohere. We also announced new capabilities in Azure AI Content Safety including:

• Correction to help fix hallucination issues in real time before users see them, now available in preview.
• Protected Material Detection for Code to help detect pre-existing content and code. This feature helps developers explore public source code in GitHub repositories, fostering collaboration and transparency, while enabling more informed coding decisions.

Lastly, we announced new evaluations to help customers assess the quality and security of outputs and how often their AI application outputs protected material.
