Building your own vertical agent with AG2 AgentOS
2025-06-06 , Grand Hall

In this tutorial, we will cover basic and advanced agentic design patterns in AG2 and we will go through practical implementations to demonstrate AI agents in action.


Majority of knowledge work nowadays requires comprehensive, integrated research in order to uncover deep insights. While existing technologies have advanced, the data deluge and fragmented complex systems mean extensive resources and specialised teams are still necessary. AG2 AgentOS changes this paradigm by seamlessly enabling multi-agent systems to solve complex tasks and aggregate diverse data sources to achieve outcomes that would usually take even experts a lot of time.

In this session, we will cover:
1. Design patterns and practical implementations to demonstrate AI agents in action such as
- Customized GroupChat
- Code execution
- Deep Research Agent
- Swarm
- Tool using
- Async chats
- Dynamic instructions
- Realtime Agent
- GraphRAG
- Structured Output
2. The anatomy of a Vertical AI agent application and how to seamlessly integrate multiple agents powered by models from OpenAI, Anthropic, Gemini, and open-weight providers, and a diverse range of tools to build your own vertical agent.
3. We will utilise components we’ve learned to collect information from the internet, connect to a data room, and create various modelling functions to replicate analysis done in a technical and commercial deep dive in a startup.
4. Explain how to contribute to the thriving AI agent ecosystem.

Target industries and use cases:
1. Industries that require deep research, such as finance, healthcare, science & engineering. Research/Analysis/Science use cases: Deep Research Agent, SciAgents, Financial Analysis, AutoML Agent.
2. Industries involving customer support, such as e-commerce, education, social media. Customer-oriented use cases: Travel Planner, Order Management, Realtime ToDo Assistant, Email Management, -Social Media Management, Youth Helper.
3. Industries involving heavy software design & development, such as gaming, web, data engineering. Software-oriented use cases: Game Design Agents, Web Agent, Software Testing Agent

At the end of the tutorial, the attendees would gain a better understanding of agent-oriented programming concepts and how to reach production-readiness 10x faster. Through the examples given, they will be able to construct effective multi-agent systems to solve complex tasks. They will have reusable building blocks to customize for their own vertical agent.
