Prompt flow
Prompt Flow is an open-source Microsoft toolset for designing, evaluating, testing, and deploying workflows that combine prompts, language models, and code.
AI Agents in Action
A visual editor is a graphical interface for inspecting and modifying a flow without directly editing its underlying configuration text.
- How it is used
- Supports systematic prompt engineering by constructing agent profiles, running flows, deploying applications, and evaluating variations at scale.
- How deep it goes
- Explains setup, YAML and Jinja2 flows, deployment, batch evaluation, rubrics, and DAG execution, but defers broader implementation details.
- Examples
- Uses a time-travel movie recommender, question-answering flow, prompt variants, local web app, and self-consistency batch run.
- What you can do after
- Build prompt flows, run and compare variations, evaluate outputs with rubrics, and deploy a flow as a local application or Docker service.
Generative AI in Action
Prompt Flow is a Microsoft open-source toolset for designing, evaluating, testing, and deploying workflows that combine prompts, language models, and code.
- How it is used
- Frames prompt engineering as an operational workflow for designing, evaluating, testing, and deploying AI applications.
- How deep it goes
- Defines the operational role and surrounding risks but does not provide a detailed flow implementation or API walkthrough.
- Examples
- Uses an operational lifecycle figure and situates Prompt Flow alongside MLflow and Traceloop observability examples.
- What you can do after
- Build and operate prompt-driven workflows while evaluating quality and recognizing production observability and security concerns.
