The Road to Agentic AI

Fill out the form above to watch the full length session!

What you'll learn

This session demystifies how large language models (LLMs) like ChatGPT and Copilot actually work. Learn what’s really happening under the hood—beyond the hype—to better engage with these tools and drive more consistent, reliable results.

Who should watch

This session is ideal for:

Business and tech leaders integrating AI tools
Enterprise users frustrated with “hit-or-miss” results
Anyone serious about developing prompt engineering skills
Teams tasked with AI implementation or strategy

Key takeaways

LLMs aren’t thinking; they’re predicting: These models don’t “understand” your input; they use math to predict the most probable next word based on training data, prior context, and token relationships in a multi-dimensional space.
Context is everything: The more specific and intentional your prompt, the higher the probability you’ll get the result you want. Every word you include becomes part of the model’s decision-making process—so vague or contradictory prompts reduce accuracy.
You’re not asking a question. You’re setting a stage: Prompting is about shaping a narrative. Leading language, tone, and even emotional cues all influence the output. Polite or frustrated language can subtly shift how the model responds.
Manage your inputs like a pro: Keep your prompts clean by removing failed attempts rather than re-prompting in the same thread. Watch for misleading context or mixed requests—everything in your session impacts what comes next.
