Building AI Agents: Focus on Reasoning, Iterate ACI for Optimized Performance
As the co-founder and CTO of Rosco, I've learned valuable lessons about building AI agents and multi-agent systems, including the importance of focusing on reasoning over knowledge, iterating on the agent computer interface, and designing effective manager agents to incentivize worker agents.
- 1. Patrick is the co-founder and CTO of Rosco, which rebuilt its product around AI agents two years ago.
- 2. An AI agent is defined by three criteria: ability to take directions, access to tools with responses, and autonomous reasoning for tool usage.
- 3. A key lesson learned was focusing on enabling the agent to think rather than limiting it to what the underlying model knows.
- 4. Rosco's product enables an AI agent to search and query enterprise data in a warehouse.
- 5. Limitations arise when focusing on knowledge over reasoning, such as writing SQL queries with given data.
- 6. Discreet tool calls for retrieval help agents find relevant context for their actions.
- 7. Reasoning models allow models to attempt finding data first and then admit if they cannot, rather than forcing a query response.
- 8. GPT 40 may write bad queries regardless of the underlying data's presence or ability to answer a question.
- 9. Small tweaks in agent-computer interface (ACI) syntax and structure can significantly impact an agent's accuracy and performance.
- 10. The format of the response depends on the model, with GPT 40 preferring JSON over markdown and Claude requiring XML.
- 11. The actual model making decisions should be generally intelligent for best results, even if other tasks run on cheaper models.
- 12. Model hallucinations can indicate how a model expects tool calls to be defined, helping improve agent performance.
- 13. Fine-tuning models is often a waste of time, as it may decrease reasoning and overfit the model to specific tasks.
- 14. Choosing an abstraction or framework should depend on end goals and production requirements.
- 15. An agent's setup, user experience, connections, and security protocols are more valuable than system prompts.
- 16. Designing and executing multi-agent systems requires a manager agent to delegate subtasks to worker agents.
- 17. Implementing a manager agent helps prevent the main agent from becoming overwhelmed by too much information.
- 18. A "two pizza rule" applies to the number of agents working together, typically between 5 and 8, for optimal task completion.
- 19. Incentivizing the manager agent is crucial for effective multi-agent team design.
- 20. The manager agent should rely on worker agents' output to achieve broader objectives.
- 21. Rosco's blog post at asb.com provides more details about designing effective multi-agent teams.
- 22. Understanding and avoiding common mistakes in agent system design can save time and resources.
- 23. Model reasoning abilities are essential for user satisfaction, as models with logical fallacies will negatively impact the user experience.
- 24. Producing a high-quality agent product involves designing an effective ecosystem around the agent, including user interaction, connections, and security protocols.
