Introduction
Today we are announcing the General Availability (GA) of Azure Machine Learning prompt flow, marking the next step in Azure AI empowering engineers and data scientists to build quality generative AI applications. Prompt flow was initially offered as a feature in Azure Machine Learning, and designed to streamline the prompt engineering process. Through our preview, we have enhanced prompt flow significantly, in large part based on customer feedback. We have refined it for enterprises, improving the tooling for developers to incorporate evaluation capabilities as well as leverage their existing CICD paths for applications by formalizing our asset management and code-first experiences. Through prompt tuning, evaluation, experimentation, orchestration, and LLMOps for automation, prompt flow significantly accelerates the journey from development to production, embodying a trusted platform for LLM application development & deployment.
In the prompt flow preview blog, we delved into the core functionalities of prompt flow that simplified the iterative process of prompt development, offering a structured workflow from ideation through refinement to deployment. The essence of prompt flow remains intact - providing a robust foundation for developers to harness the full potential of LLMs, tailored to specific business scenarios.
As we unveil the General Availability of prompt flow, we extend the horizon further with enhanced features aimed at operationalizing LLM applications via LLMOps, bolstering enterprise readiness, and fostering an open, collaborative ecosystem. This chapter unfolds the new avenues opened by the GA release, setting a solid steppingstone for building production ready LLM applications efficiently with confidence.

Automate the LLM Apps Building Through Code and LLMOps
The endeavor of constructing Large Language Model (LLM) applications is significantly bolstered by a robust development environment. Prompt flow pioneers a code-first approach, treating flow assets as files, thereby promoting versioning and collaboration via any source code management tool. This foundation is pivotal as it seamlessly transitions into the realm of LLMOps, resonating with DevOps principles, to streamline the entire process from development to deployment. The essence of LLMOps lies in automation, continuous monitoring, evaluation, and fostering a collaborative atmosphere among development, data science, and operations teams. This structured approach substantially reduces the time from development to deployment while ensuring the quality and reliability of LLM applications.
The prompt flow SDK and CLI, unveiled for review as open source since September, have now attained a significant milestone with the General Availability (GA) release, signifying its v1.0 for enhanced stability and backward compatibility. These tools are instrumental in:
- Version Control: Manage various versions of your flow assets such as prompts, code, configurations, and environments via code repo, with the capability to track changes and rollback to previous versions when necessary, promoting a collaborative ethos among team members.
- Package and Deploy: Leverage the SDK/CLI to package and build the flow, readying deployment artifacts for seamless deployment either in Azure or locally.
- Workflow Automate: Utilize the SDK/CLI to automate various facets like connection setup, prompt tuning, flow evaluation, experimentation and CICD, thus significantly reducing the requisite time and effort.

To further expedite the LLM application development journey, a solution accelerator template for LLMOps, based on the prompt flow SDK/CLI, has been crafted. This template provides a predefined, customizable workflow blueprint, empowering developers to swiftly kickstart their LLM application projects with embedded best practices. The template encompasses:
- Preconfigured Workflows: Featuring preconfigured workflows (Azure DevOps pipelines or GitHub actions) for prompt engineering, evaluation, and deployment, which substantially reduce setup time.
- Customization: Tailor the template to align with your specific requirements, organizational goals, and workflow preferences.
- Seamless Integration: The template integrates impeccably with the Prompt Flow SDK/CLI, presenting a comprehensive solution for efficient LLM application development and deployment.
