Welcome, humans.

I [Pete] am at the Nvidia conference this week and I have battle scars fighting off a bajillion other techies trying to get a selfie with Nvidia CEO Jensen Huang. And I still couldn’t get one.

Back to the gym...

Here’s what you need to know about AI today:

• Twitter helps us demystify GPTs at work.

• Resources that teach you how to build your own GPTs.

• We share a hot new tip for prompting chatbots.

• A new AI startup makes new AI models by “breeding” them.

20 ways to use GPTs at work (feat. Lenny Rachitsky).

If you haven’t started using GPTs, you need to read this:

GPTs are custom versions of ChatGPT designed to do specific tasks, like write YouTube captions (see our pt. 1, pt. 2 & pt. 3 on GPTs). 

Lenny Rachitsky crowdsourced 20 ways companies are already using GPTs to be more productive at work—here are a few of our faves:

1. GPT that searches employee databases and answers Q’s like “Who is the eng lead for X”.

2. GPT that helps employees with goal setting using the SMART framework. 

3. GPT that generates takeaways from sales convos. 

4. GPT that simulates what different customers might say about a product. 

Read the entire article here. 

If you’re new to this “AI thing”, go explore GPTs on OpenAI’s GPT Store and search for ones related to your workflows (we’ve been loving the Data Analyst GPT lately). 

To create your own GPT:

1. Read our guide.

2. Read OpenAI’s guide. 

3. Get ChatGPT+. 

4. Watch this podcast with our pals Dan Shipper and Logan Kilpatrick

& Lenny says step #5 best here:

“Once you get the initial version set up, you can then upload ‘knowledge’—decks, PDFs, spreadsheets, and any other documents that give the GPT more information on your specific context and company. For example, you can upload your roadmap, your company values, your career ladders, etc. The more you give it, the better it does. Think of it like onboarding a person—what context would you want them to have to do their job well?”

Prompting tip: describe what “good” looks like.

Lesson 8 of our Intro to ChatGPT course (free!) teaches the RACEF prompt framework: Role, Action, Context, Examples, Format.

Without the RACEF framework:

With the RACEF framework:

Example output (Claude 3): “Elevating real estate agents' social media presence, one TikTok and Instagram post at a time.”

We can do better. Try adding a description of what a good output would be like:

New example output (Claude 3): "‘For sale’ into ‘sold’ with a single scroll”

Way better! Give it a shot with your next prompt and let us know how it went by replying to this email.

Around the Horn.

• Bloomberg trained its own model, then found out just using out-of-the-box GPT-4 was better.

• AI-generated conspiracy theory videos are flooding TikTok.

• Cohere is looking for a $5B valuation in a new funding round, with just $22M in annualized revenue.

• Sakana AI announced a new way of making AI models that’s based on evolution and natural selection.

• Scammers are using AI to steal people’s tax refunds.
