Preference fine-tuning (preview)

Direct preference optimization (DPO) is a new alignment technique for large language models, designed to adjust model weights based on human preferences. Unlike reinforcement learning from human feedback (RLHF), DPO does not require fitting a reward model and uses simpler data (binary preferences) for training. This method is computationally lighter and faster, making it equally effective at alignment while being more efficient. DPO is especially useful in scenarios where subjective elements like tone, style, or specific content preferences are important. We’re excited to announce the public preview of DPO in Azure OpenAI Service, starting with the gpt-4o-2024-08-06 model.

For fine-tuning model region availability, see the models page.

Stored completions & distillation

Stored completions allow you to capture the conversation history from chat completions sessions to use as datasets for evaluations and fine-tuning.

November 2024

Vision Fine-tuning GA

Vision fine-tuning with GPT-4o (2024-08-06) in now Generally Available (GA).

Vision fine-tuning allows you to add images to your JSONL training data. Just as you can send one or many image inputs to chat completions, you can include those same message types within your training data. Images can be provided either as URLs or as base64 encoded images.

For fine-tuning model region availability, see the models page.

NEW AI abuse monitoring

We are introducing new forms of abuse monitoring that leverage LLMs to improve efficiency of detection of potentially abusive use of the Azure OpenAI service and to enable abuse monitoring without the need for human review of prompts and completions. Learn more, see Abuse monitoring.

Prompts and completions that are flagged through content classification and/or identified to be part of a potentially abusive pattern of use are subjected to an additional review process to help confirm the system’s analysis and inform actioning decisions. Our abuse monitoring systems have been expanded to enable review by LLM by default and by humans when necessary and appropriate.

October 2024

NEW data zone standard deployment type

Data zone standard deployments are available in the same Azure OpenAI resource as all other Azure OpenAI deployment types but allow you to leverage Azure global infrastructure to dynamically route traffic to the data center within the Microsoft defined data zone with the best availability for each request. Data zone standard provides higher default quotas than our Azure geography-based deployment types. Data zone standard deployments are supported on gpt-4o-2024-08-06, gpt-4o-2024-05-13, and gpt-4o-mini-2024-07-18 models.

For more information, see the deployment types guide.

Global Batch GA

Azure OpenAI global batch is now generally available.

The Azure OpenAI Batch API is designed to handle large-scale and high-volume processing tasks efficiently. Process asynchronous groups of requests with separate quota, with 24-hour target turnaround, at 50% less cost than global standard. With batch processing, rather than send one request at a time you send a large number of requests in a single file. Global batch requests have a separate enqueued token quota avoiding any disruption of your online workloads.

Key use cases include:

  • Large-Scale Data Processing: Quickly analyze extensive datasets in parallel.

  • Content Generation: Create large volumes of text, such as product descriptions or articles.

  • Document Review and Summarization: Automate the review and summarization of lengthy documents.

  • Customer Support Automation: Handle numerous queries simultaneously for faster responses.

  • Data Extraction and Analysis: Extract and analyze information from vast amounts of unstructured data.

  • Natural Language Processing (NLP) Tasks: Perform tasks like sentiment analysis or translation on large datasets.

Model deprecations and retirements

We have added a page to track model deprecations and retirements in Azure OpenAI Service. This page provides information about the models that are currently available, deprecated, and retired.

2024-03-01-preview API released

2024-03-01-preview has all the same functionality as 2024-02-15-preview and adds two new parameters for embeddings:

  • encoding_format allows you to specify the format to generate embeddings in float, or base64. The default is float.
  • dimensions allows you set the number of output embeddings. This parameter is only supported with the new third generation embeddings models: text-embedding-3-large, text-embedding-3-small. Typically larger embeddings are more expensive from a compute, memory, and storage perspective. Being able to adjust the number of dimensions allows more control over overall cost and performance. The dimensions parameter isn't supported in all versions of the OpenAI 1.x Python library, to take advantage of this parameter we recommend upgrading to the latest version: pip install openai --upgrade.

If you're currently using a preview API version to take advantage of the latest features, we recommend consulting the API version lifecycle article to track how long your current API version will be supported.

Update to GPT-4-1106-Preview upgrade plans

  • New RAI models

    • Jailbreak risk detection: Jailbreak attacks are user prompts designed to provoke the Generative AI model into exhibiting behaviors it was trained to avoid or to break the rules set in the System Message. The jailbreak risk detection model is optional (default off), and available in annotate and filter model. It runs on user prompts.
    • Protected material text: Protected material text describes known text content (for example, song lyrics, articles, recipes, and selected web content) that can be outputted by large language models. The protected material text model is optional (default off), and available in annotate and filter model. It runs on LLM completions.
    • Protected material code: Protected material code describes source code that matches a set of source code from public repositories, which can be outputted by large language models without proper citation of source repositories. The protected material code model is optional (default off), and available in annotate and filter model. It runs on LLM completions.

    Configure content filters

  • Blocklists: Customers can now quickly customize content filter behavior for prompts and completions further by creating a custom blocklist in their filters. The custom blocklist allows the filter to take action on a customized list of patterns, such as specific terms or regex patterns. In addition to custom blocklists, we provide a Microsoft profanity blocklist (English). Use blocklists

Today, the service logs request/response data for the purposes of abuse and misuse detection to ensure that these powerful models aren't abused. However, many customers have strict data privacy and security requirements that require greater control over their data. To support these use cases, we're releasing a new process for customers to modify the content filtering policies or turn off the abuse logging for low-risk use cases. This process follows the established Limited Access process within Azure AI services and existing OpenAI customers can apply here.​

  • Customer managed key (CMK) encryption. CMK provides customers greater control over managing their data in Azure OpenAI by providing their own encryption keys used for storing training data and customized models. Customer-managed keys (CMK), also known as bring your own key (BYOK), offer greater flexibility to create, rotate, disable, and revoke access controls. You can also audit the encryption keys used to protect your data. Learn more from our encryption at rest documentation.

  • Lockbox support​
