🚨 New @a16z thesis: AI x commerce

AI will change the way we shop - from where we find products to how we evaluate them, when we buy, and much more.

What types of purchases will be disrupted, and where does opportunity exist in the age of AI?

More from me + @arampell 👇

To start - what are the categories of commerce? (for consumers)

We divide them by level of consideration, from impulse buys to life purchases.

These have vastly different processes - you don't buy a new backpack and a car in the same way - which means the way AI touches each purchase category will vary.

Some thoughts on how this might shake out:

1) Impulse buys - the candy bars you pick up at the checkout counter (or their digital equivalent).

You don't do a lot of research in advance, so it's tough for AI to play a role in your shopping process.

But the algorithms on social apps will continue to improve + target you with more relevant impulse purchases (like that cat-shaped water bottle or $15 t-shirt from your favorite show).

Spent a few days testing out Imagine - @grok's new image and video generator.

And I've got a good sense of where it spikes, what the limitations are, and how to use it.

Curious about how it stacks up? Keep reading 👇

@grok First: all video generation on Grok starts from an image.

You can either upload a photo from your camera roll, or generate one in the app.

Image generation is INSANELY fast. It literally makes new images as you scroll. As you can see, the slowest part is my typing 😅

Once you have an image, it's time to animate.

You can write your own prompt (click "custom"), or auto-generate a video that's fun, spicy, or normal.

I love the auto-prompting - many people don't know how to prompt or want to see what the model does.

It takes ~17 seconds to generate a video (I trimmed here so you can see "normal" vs. "fun").

What's blowing up in AI video this week?

I curated the most viral & interesting formats across platforms - and recreated them to share workflows.

The list and how to make them 👇

1) Nighttime home video footage

Two types of this video are going viral on Reels and TikTok:

a) Cats bringing home or interacting with an unexpected friend (this one from wowcsly has 120M views 🤯)

b) Animal visitors jumping on a trampoline (unfortunate ending for this bear)

https://x.com/venturetwins/status/1948771505783144641

How to - this one is pretty easy to make using Veo 3 Fast.

You can use a basic prompt on text-to-video mode.

Or if you want more control, you can use the new "annotate image" feature (in tweet below) on frames-to-video.

I reverse-engineered the viral "AI zoom" workflow for any animal and scene.

(and no, they don't all have to be flipping you off)

How to do it 👇

https://twitter.com/venturetwins/status/1947517167613906949

Start with the central image that you want the camera to pause on after zooming in.

If you're going to do the middle finger, you might have to generate a normal image + ask 4o to edit it.

You can also use in your own pet! To place them in a cool scene, use Flux Kontext. E.g. I uploaded Finn and asked for him to be on the streets of Tokyo.

Then, take the image to @higgsfield_ai and use the "Earth zoom out" effect.

For prompts: I just describe the animal, the expression, and say it zooms out to be above the earth.

Turn on enhance prompt and it will write a longer one for you, e.g. -

A capybara sits defiantly in the middle of a bustling Tokyo street, his middle finger up. The camera initiates a smooth, dramatic zoom out, pulling away rapidly from the capybara. As it rises, it glides over the lively street filled with pedestrians, and ascends high above the cityscape. The view expands further, soaring through the clouds and atmosphere, culminating in a breathtaking sight of Earth spinning in the cosmos, evoking a sense of wonder and insignificance.

You can now make AI video that's "filmed" in a real location 🤯

Like this Stormtrooper's fundraising vlog that tours @a16z's SF office - and looks just like the real thing!

It's easy to put AI characters in your own office, home, or vacation spot. How to do it 👇

This uses Veo 3 image-to-video.

Easy way: upload a frame of your location. Prompt the character(s) you want to add, the direction of their movement, and what you want them to do or say.

My prompt for this: "stormtrooper youtuber walks from the right into the frame past the chairs. he then pauses, turns back to the camera, and whispers 'It's time!' "

(I cropped the beginning for time reasons)

To make it more complex, you can play around with framing.

Use the "fast jump/cut" prompt (from @MartinNebelong) to take a different angle on a scene from a single image.

I'm so impressed by how it inferred what a selfie from someone on the couch would look like.

Prompt: fast jump / cut from frame 1. pov selfie-style vlog of a male stormtrooper youtuber sitting in one the couch in frame 1. he says "false alarm, I got here early. I'm researching the investor I'm going to meet with. I think her name is Justine?"

🚨 How to make longer videos with Veo 3:

I've spent hours experimenting with the new image-to-video mode.

And I've found a way to generate consistent + cohesive stories that are much longer than the 8 second limit.

Tutorial and tips to make it work 👇

To begin: Veo 3 can still only generate 8 seconds at a time.

But you can essentially "extend" this by taking the end frame from one clip and using it as the start frame for your next clip.

This sounds easy, but it's pretty finicky. My learnings so you don't waste credits ⬇️

(1) Remember the end frame from your last clip is the ONLY context the model has.

Therefore - any characters, objects, or environments that you want to re-appear later need to be in that frame.

This clip, for example, doesn't work if I want the woman to be in the next scene.
