Data to train AI models increasingly comes from other AI models in the form of synthetic data, which can fill in chatbots' knowledge gaps but also destabilize them.
The big picture: As AI models expand in size, their need for data becomes insatiable — but high quality human-made data is costly, and growing restrictions on the text, images and other kinds of data freely available on the web are driving the technology's developers toward machine-produced alternatives.
Nearly all of the world's oceans are in the midst of "unusual warmth," warns a leading NOAA scientist who notes this has contributed to the extreme heat baking much of the Northern Hemisphere this summer.
Why it matters: "Even small rises in temperature can disrupt marine ecosystems, cause some species to relocate, and increase disease risks," said Stats NZ's Stuart Jones in a statement. "It also contributes to sea-level rise as the warmer water expands."
