Tried to use #Imagen to generate collectable Japanese postage stamps about VR cats. I love these results!

“Ukiyo-e painting of a cat hacker wearing VR headsets, on a postage stamp” ❤️
These metaverse cats come in all shapes and sizes.

Don’t worry, these VR cats are only slightly sentient 🙃

Interview with Jürgen Schmidhuber, ‘Father Of Modern AI’, who says his life’s work won’t lead to dystopia.

He goes quite in depth into his views about the future of AI and AGI. A refreshing view of things, compared to other ‘influential leaders’ in AI.

Schmidhuber’s take on whether it makes sense to ban large language models like GPT in education, and future of human labor.

“Laziness and efficiency is a hallmark of intelligence. Any intelligent being wants to minimize its efforts to achieve things.”

@SchmidhuberAI On open-source AI, “I signed this open letter by @laion_ai because I strongly favor the open-source movement. And I think it's also something that is going to challenge whatever big tech dominance there might be at the moment.”

A #StableDiffusion model trained on images of Japanese Kanji characters came up with “Fake Kanji” for novel concepts like Skyscraper, Pikachu, Elon Musk, Deep Learning, YouTube, Gundam, Singularity, etc.

They kind of make sense. Not bad!
This is similar to the “Fake Kanji” with recurrent neural network experiments I did many years ago, when computers were 1000x less powerful :) Kind of fun to see updated results with modern diffusion models.

These were what I generated back in 2015:

Excited to announce the release of Stable Diffusion 2.0!

Many new features in v2:

• Base 512x512 and 768x768 models trained from scratch with new OpenCLIP text encoder
• X4 upscaling text-guided diffusion model
• New “Depth2Image” functionality

Blog: stability.ai/blog/stable-di…
This release is led by @robrombach @StabilityAI

The new SD2 base model is trained from scratch using OpenCLIP-ViT/H text encoder (github.com/mlfoundations/…), with quality improvements over V1. It is fine-tuned using v-prediction (arxiv.org/abs/2202.00512) to produce 768x768 images:
A new 4x up-scaling text-guided diffusion model, enabling resolutions of 2048x2048 (or even higher!), when combined with the new text-to-image models in this release.

Made possible using Efficient Attention in (github.com/facebookresear…).

Example of 128x128 to 512x512 up-scaling:

Tried some interesting prompts to test OpenAI’s new reduced-bias #dalle2 #dalle model that will generate images of people that more accurately reflect the diversity of the world’s population.

Here’s another four samples of the same prompt.

The most interesting and viral images you see produced by text-to-image models are not merely the results of the deep learning models themselves, but rather the result of a complex feedback loop between a human neural net🧠 interacting with an artificial neural net🤖.

🧵Thread👇
You can clearly see this, because the prompts for images that end up going viral for one model, clearly don’t “work” for another model.

The best images are chosen from evolutionary selection at the community level, and each image are the result of human/model iterative feedback:
From the #dallemini phenomenon, it’s also clear that the most viral content is not related to particular art styles, or whether the model can produce high quality images (reflected in training data). But rather, whether the model can portray cultural items that people talk about.

Good Morning!

I tried to use text-to-image models to combine historical architecture with other locations around the world.
