Chat LLM or AI Agent? Know which to use and when.


By Manuel Mitola, CELforPharma faculty member of The AI for Pharma Marketing Course

An AI agent is not better than a chat LLM, and a chat LLM is not better than an AI agent. They both have their place. The real question is: when should you use one, and when should you build the other? This framework helps pharma marketing professionals answer that question, with practical examples from the field.
 

What the framework covers

  • Reusability: When to use a quick chat versus build a reusable tool for your team
  • Knowledge access: General AI knowledge versus your own brand materials and SOPs
  • Compliance guardrails: How to embed pharma-specific rules and MLR review steps
  • Integrations and automation: CRM, Veeva, SharePoint: when connections make sense
  • Team scalability: Why individual prompting leads to inconsistent outputs across the team
  • Cost versus effort: Setup, maintenance, and when the investment pays off
