Black Holes or Black Hole Stars? Astronomers Spar Over Webb Telescope's Little Red Dots
Charlie Wood explains the debate over James Webb's mysterious little red dots: whether they are standard supermassive black holes or black hole stars—colossal hydrogen shells powered by hidden black holes—and what that would mean for how the first big black holes formed.

How OpenAI Used Its Own LLMs to Design Its Jalapeño Chip
On 25 August, OpenAI fully unveiled Jalapeño, the company’s debut AI accelerator chip. Jalapeño delivers up to 13.4 petaflops of 4-bit compute and accesses 232 gigabytes of the most advanced memory available, linking to it at a blazing 15.4 terabytes per second. Benchmarks cited by OpenAI show that Jalapeño can reduce end-to-end latency (the time between prompt to last token) by up to 3.6 times when compared to Nvidia’s GB300—a chip the company currently relies on—and do so while consuming less power. Whether these figures translate into real-world gains once Jalapeño…
