CodeRabbit raises $60M, valuing the 2-year-old AI code review startup at $550M

Harjot Gill was running FlexNinja, an observability startup he co-founded several years after selling his first startup Netsil to Nutanix in 2018, when he noticed a curious trend. “We had a team of remote engineers who were starting to adopt AI code generation on GitHub Copilot,” Gill told TechCrunch. “We saw that adoption happen, and it was very clear to me that as a second-order effect, it’s going to cause bottlenecks in the code review.” In early 2023, Gill started CodeRabbit, an AI-powered

Rabbit Overhauls Its R1 AI Device With a Major Touch-Focused OS Update

The Rabbit R1, a dedicated AI device that received middling reviews last year, just received a major software update overhauling the entire operating system, Rabbit Inc. founder and CEO Jesse Lyu said Monday in a video posted on X. In the video, Lyu acknowledges the R1's shortcomings, saying his team was overwhelmed by the hype and expectations the device received. Since then the R1 has seen 30 updates, but with rabbitOS2 the device's operating system is getting a complete overhaul. RabbitOS2

Colorado Residents Are Spotting Weird-Looking Rabbits With Black Horns and Mouth Tentacles

People in Fort Collins, Colorado, are seeing rabbits with black horns and tentacles that wouldn’t look out of place in a horror movie. Though frightening, their appearance is caused by a known virus that’s harmless to humans. Journalist Amanda Gilbert documented the town sightings in an article for local outlet 9NEWS last Friday. Colorado Parks and Wildlife officials say the rabbits are afflicted with a virus that causes wart-like projections to emerge from their faces—a condition that likely e

Researchers create artificial blood for on-the-spot use in accidents and combat

Forward-looking: In a laboratory at the University of Maryland, a team of researchers is tackling one of emergency medicine's most persistent challenges: how to deliver life-saving blood transfusions to patients who are miles from the nearest hospital. Their experimental solution isn't stored in a refrigerator but in the form of a lightweight powder – raising hopes among scientists and military officials that trauma care could soon reach accident scenes and battlefields alike, where blood loss r

Changing one gene can restore some tissue regeneration to mice

Regeneration is a trick many animals, including lizards, starfish, and octopuses, have mastered. Axolotls, a salamander species originating in Mexico, can regrow pretty much everything from severed limbs, through eyes and parts of brain, to the spinal cord. Mammals, though, have mostly lost this ability somewhere along their evolutionary path. Regeneration persisted, in a limited number of tissues, in just a few mammalian species like rabbits or goats. “We were trying to learn how certain anima

Rabbit shows off the AI agent it should have launched with

is a weekend editor who covers the latest in tech and entertainment. He has written news, reviews, and more as a tech journalist since 2020. The Humane AI Pin has collapsed, but Rabbit is still kicking. The company published a blog post and video today showing off a “generalist Android agent,” slowly controlling apps on a tablet in much the same way that Rabbit claimed its R1 device would over a year ago. (It couldn’t, and can’t.) The work builds on LAM Playground, a “generalist web agent” Rabb
