👉 Runway has introduced Gen-3 Alpha, a new AI model that offers significant improvements in detail, consistency, and motion representation in the generated videos compared to its predecessor, Gen-2.


Runway has introduced Gen-3 Alpha, a new AI model for video generation. According to Runway, it represents a “significant improvement” over its predecessor, Gen-2, in terms of detail, consistency, and motion representation.

Gen-3 Alpha has been trained on a mix of video and images and, like its predecessor, which was launched in November 2023, supports text-to-video, image-to-video, and text-to-image functions, as well as control modes such as Motion Brush, Advanced Camera Controls, and Director Mode. Additional tools are planned for the future to provide even greater control over structure, style, and motion.

Runway Gen-3 Alpha: First model in a series with new infrastructure

According to Runway, Gen-3 Alpha is the first in a series based on a new training infrastructure for large multimodal models. However, the startup does not reveal what specific changes the researchers have made.

Large language models (LLMs), such as the GPT-4 model underpinning the widely used conversational platform ChatGPT, have surprised users with their ability to understand written prompts and generate suitable responses in various languages. Some of us may thus wonder: are the texts and answers generated by these models so realistic that they could be mistaken for those written by humans?

Scientists can’t address the origins of life without having a basic understanding of evolution.

You’d think that would make the origins of life a popular research topic for evolutionary biologists. But Maria Kalambokidis, Ph.D. candidate in Ecology, Evolution and Behavior, and recent recipient of the NASA Future Investigators Fellowship, may be one of only a handful across the globe investigating the topic. She thinks it might be because the origins of life, also called abiogenesis, has mostly been studied by chemists.

“It’s difficult to come into the field when you have a completely different scientific background than someone else,” says Kalambokidis. “There are insights from evolution that you might miss by only taking the perspective of a chemist.”

The research team thinks that super-color-charged black holes may have impacted the balance of fusing nuclei in the infant universe. Though the exotic objects ceased to exist in the first moments of the cosmos, future astronomers could potentially still detect this influence.

“Even though these short-lived, exotic creatures are not around today, they could have affected cosmic history in ways that could show up in subtle signals today,” study co-author David Kaiser, a professor of physics at the Massachusetts Institute of Technology (MIT), said in a statement.
