**Prompt flow** is a suite of development tools designed to streamline the end-to-end development cycle of LLM-based AI applications, from ideation, prototyping, testing, evaluation to production deployment and monitoring. It makes prompt engineering much easier and enables you to build LLM apps with production quality.
With prompt flow, you will be able to:
- **Create and iteratively develop flow**
- Create executable [flows](https://microsoft.github.io/promptflow/concepts/concept-flows.html) that link LLMs, prompts, Python code and other [tools](https://microsoft.github.io/promptflow/concepts/concept-tools.html) together.
- Debug and iterate your flows, especially [tracing interaction with LLMs](https://microsoft.github.io/promptflow/how-to-guides/tracing/index.html) with ease.
- **Evaluate flow quality and performance**
- Evaluate your flow's quality and performance with larger datasets.
- Integrate the testing and evaluation into your CI/CD system to ensure quality of your flow.
- **Streamlined development cycle for production**
- Deploy your flow to the serving platform you choose or integrate into your app's code base easily.
- (Optional but highly recommended) Collaborate with your team by leveraging the cloud version of [Prompt flow in Azure AI](https://learn.microsoft.com/en-us/azure/machine-learning/prompt-flow/overview-what-is-prompt-flow?view=azureml-api-2).

## Installation
To get started quickly, you can use a pre-built development environment. **Click the button below** to open the repo in GitHub Codespaces, and then continue the readme!
[](https://codespaces.new/microsoft/promptflow?quickstart=1)
If you want to get started in your local environment, first install the packages:
Ensure you have a python environment, `python>=3.9, <=3.11` is recommended.
```sh
pip install promptflow promptflow-tools
```
## Quick Start ⚡
**Create a chatbot with prompt flow**
Run the command to initiate a prompt flow from a chat template, it creates folder named `my_chatbot` and generates required files within it:
```sh
pf flow init --flow ./my_chatbot --type chat
```
**Setup a connection for your API key**
For OpenAI key, establish a connection by running the command, using the `openai.yaml` file in the `my_chatbot` folder, which sExcerpt of 9,879 characters
