#jupyter_notebook Unsloth is a tool that makes it much faster and easier to fine-tune large language models like Llama, Mistral, and Gemma, even on regular computers or single GPUs. It uses smart tricks to speed up training by 2 to 5 times and cuts memory use by up to 70%, so you can train models quickly without needing expensive hardware[1][3][4]. The benefit is that anyone—developers, researchers, or AI fans—can create custom AI models for different tasks, from chatting to vision, in less time and with less hassle, using ready-made notebooks and guides for popular models[3][5]. https://github.com/unslothai/notebooks

🪐 In the constellation Hydra, astronomers have found R Hydrae, a star that pulses in brightness over a period of about 385 days. This "Mira variable" expands and contracts like a cosmic heartbeat, changing size and light output as it nears the end of its life, giving scientists clues about the future fate of our own Sun. ✨ #stars⚡#hydra⚡#pulsation⚡#nasa⚡#galaxy⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries

🪐 In the constellation Vela, the star system HD 74423 displays an unusual cosmic phenomenon: its shape is teardrop-like rather than round, caused by the powerful gravitational pull of a nearby red dwarf companion. This distortion leads to "heartbeat" pulsations—brightenings and dimmings in rhythm with the stars’ orbits—making HD 74423 the first known one-sided pulsating star in our galaxy. ✨ #Vela⚡#heartbeatstars⚡#pulsation⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries
