What’s Mosaic AI Agent Framework?

The Mosaic AI Agent Framework is a set of instruments on Databricks that helps builders create, deploy, and handle AI brokers, similar to these utilized in Retrieval-Augmented Technology (RAG). It integrates with frameworks like LangChain and LlamaIndex and makes use of Databricks options like Unity Catalog for information governance and tool-calling.

Builders can log and check brokers with MLflow, debug their conduct, and improve efficiency. Options like request logging, response token streaming, and overview apps make constructing and deploying AI brokers simpler for real-world use circumstances.

Use Case: Manufacturing Operations Administration Chatbot

Manufacturing Operations Administration (MOM) is essential for optimizing manufacturing processes, bettering effectivity, and sustaining competitiveness in in the present day’s quickly evolving industrial panorama.

The demand for operation administration utilizing AI brokers with pure language interfaces is quickly rising, pushed by the necessity for elevated effectivity, improved decision-making, and enhanced person experiences.

In keeping with the newest publication from Meticulous Analysis® (supply), the AI in manufacturing market is projected to succeed in $84.5 billion by 2031, at a CAGR of 32.6% through the forecast interval 2024–2031 ^[1]. This important progress underscores the rising recognition of the significance of AI-driven operation administration in varied industries.

A producing firm implementing the Mosaic AI chatbot leveraging tool-calling can help manufacturing managers in:

Bottleneck Evaluation

• Instrument operate: Queries Databricks SQL utilizing the identify_bottleneck_station operate to find out the station inflicting probably the most delays.
• Instance question: “What’s the present bottleneck within the meeting line?”
• Response: “Station 5 is the present bottleneck, with a median delay of quarter-hour per cycle.”

Stock Monitoring

• Instrument operate: Calls check_inventory_levels to retrieve real-time inventory information for a specified station.
• Instance question: “Do we have now sufficient supplies for Station 3?”
• Response: “Station 3 has sufficient supplies for the subsequent 5 manufacturing cycles.”

These queries could be simply carried out as features saved in Unity Catalog, utilizing both SQL or Python. Then an AI agent can carry out duties similar to information retrieval, code execution, and context-based decision-making by leveraging the operate calls. Whereas we gained’t dive into the specifics of establishing the agent for tool-calling right here, you possibly can check with the Databricks Generative AI Cookbook right here for detailed steering.

As soon as the Mosaic AI agent is ready up and configured to deal with varied instruments, it may be deployed as a model-serving endpoint on Databricks. This endpoint acts because the backend interface, permitting frontend purposes like chatbots to ship queries and obtain real-time insights.

Right here is the chatbot interface working regionally; later, we are going to show it after deployment to Databricks Apps.

Databricks Apps Implementation

1. Frontend with React

The React frontend gives an interactive and user-friendly interface for querying the chatbot and visualizing responses. Core options embody real-time message rendering, question submission, and bot response dealing with, interactive UI with suggestions, and Markdown assist.

Frontend Code Sending Messages to the Backend

API Shopper: Axios is used to make HTTP requests. The baseURL is dynamically set primarily based on the surroundings (growth or manufacturing).

HandleSendMessage: It captures person enter, sends the message to the /api/chat API endpoint, and updates the chat historical past with each person and bot messages.

2. Backend with FastAPI

The FastAPI backend serves because the bridge between the React frontend and Mosaic AI brokers. It routes person queries to the agent’s model-serving endpoint to get a response.

Backend Code Dealing with Consumer Queries

This API endpoint receives person messages, interacts with the Mosaic AI agent model-serving endpoint, and returns task-specific responses.

In FastAPI, the order of mounting sub-applications is essential as a result of it determines how incoming requests are routed.

app.mount("/api", api_app):

• This mounts a sub-application (api_app) on the /api route.
• Any request beginning with /api (e.g., /api/chat) is routed to this sub-application.
• This ensures that every one API-related requests are processed by the api_app occasion.

app.mount("/", ui_app):

• This mounts the static recordsdata from the consumer/construct listing on the root (/) route.
• That is usually used to serve the compiled frontend software, which embody index.html, JavaScript, CSS, and different static belongings. Many of the main UI frameworks (e.g. React, Vue and Svelte) assist compilation into such a set of belongings by way of totally different bundlers (e.g. Vite, Webpack or esbuild).
• Any request that doesn’t begin with /api will probably be routed to the ui_app.

• API Setup and Endpoint Definition: The code defines a FastAPI software with a POST endpoint (/chat) beneath the api_app occasion that factors to the Mosaic AI agent’s model-serving endpoint on Databricks.
• Dependency Injection and Request Dealing with: The endpoint makes use of FastAPI’s dependency injection mechanism (Relies upon) to inject a WorkspaceClient, which is accountable for interacting with Databricks APIs. The chat_with_llm operate takes a ChatRequest containing the person’s message, codecs it as a ChatMessage with the position USER, and sends it to the serving endpoint utilizing the consumer.serving_endpoints.question technique.
• Response Parsing and Return: The response from the agent is structured and returned as a ChatResponse to the consumer.

Deployment on Databricks Apps

1. Getting ready the Backend

• Place the FastAPI code in an app.py file.
• Outline dependencies in necessities.txt:
  
• Create an app.yaml file:
  

The command part outlines the gunicorn server configuration with the next specs:

• server.app:app: Runs your FastAPI software.
• -w 2: Makes use of two employee processes to deal with incoming requests.
• uvicorn.staff.UvicornWorker: Makes use of Uvicorn staff, that are appropriate with FastAPI’s ASGI framework.

The env part specifies key-value pairs that outline surroundings variables to go to the app ^[2]:

• title: the title of the surroundings variable.
• valueFrom: For an externally outlined worth, the title of the supply containing the worth. For instance, the title of a secret or a database desk containing the worth.

I’m mapping the surroundings variables SERVING_ENDPOINT_NAME to the Databricks useful resource model-serving endpoint agent_MODEL_NAME_FQN, the place MODEL_NAME_FQN represents the three-level namespace of Unity Catalog for catalog.db.model_name.

2. Getting ready the Frontend

• Construct the React app with npm run construct and place the static recordsdata in /consumer/construct.

Right here is the file construction:

3. Deployment Steps

1. Create the Databricks App:

2. Configure Databricks Assets:
   I’m establishing the Databricks assets to align with the options outlined within the env part of the app.yaml file. This contains configuring assets such because the model-serving endpoint (agent_MODEL_NAME_FQN).
   
   The beneath picture reveals that the chatbot app has been efficiently created:
   
3. Sync Information:
   
4. Deploy the App:
   

After executing this command, the deployment course of will take a couple of minutes. As soon as efficiently deployed, the Databricks App’s URL will probably be displayed, indicating that it’s up and working.

And you can begin chatting with it. For instance, our manufacturing effectivity is low. Discover the bottleneck, verify its effectivity, and generate an in depth report. Ship an electronic mail to [email protected] with the report. Additionally analyze the sentiment of the report.
