As the NBA season came to an end this weekend, the streets of NYC lit up with millions of diehard Knicks fans.

And although nothing can replace that feeling of being surrounded by fellow crazed fans, what happens now that the season is over?

What if you could keep engaging with your favorite players any time you wanted? You could form a unique 1:1 relationship with them through their avatar?

That’s what we’re working on. A way to reshape how fans interact with their favorite athletes, celebrities, and IP characters...to extend the relationship beyond just the streets, the bar, the arena, or the feed.

@adage featured Genies in a write-up on how AI and data are enhancing the player <> fan relationship across sports.

Technique 1: Constraint-Based Prompting

Most prompts are too open-ended. Engineers add hard constraints that force the model into a narrower solution space, eliminating 80% of bad outputs before they happen.

Template:

Generate [output] with these non-negotiable constraints:
- Must include: [requirement 1], [requirement 2]
- Must avoid: [restriction 1], [restriction 2]
- Format: [exact structure]
- Length: [specific range]

Example:

Generate a product description for wireless headphones with these constraints:
- Must include: battery life in hours, noise cancellation rating, weight
- Must avoid: marketing fluff, comparisons to competitors, subjective claims
- Format: 3 bullet points followed by 1 sentence summary
- Length: 50-75 words total

1. The Beginner Roadmap

"Teach me the basics of [Insert Skill] in a simple learning path. Explain what I need to learn first, what comes next, and what I should ignore in the beginning. Give me a short definition for each step so I understand the idea before I practice it."

I have had 3 friends end up in the hospital with stroke like symptoms, two ended up with strokes, and one is undiagnosed. Yesterday I went to the hospital with heart attack symptoms &amp; my blood pressure was 194/145.

Prolonged stress is killing us. Plz take care of yourselves.

10 years ago, I presented a security focused talk called Threat Modeling My Wife about implantable pain management devices. That talk was Sarah’s idea. She wanted to make sure the device was safe to implant in her. This year, my kids and I buried Sarah. #CRPS #Dysautonomia #EDS

Hey @WestinNanea @ClubWestin @Vistana how can I donate my StarOptions points for Nanea to those displaced in #Lahaina? Rather than have visitors, those rooms should be going to those in need.
