Nvidia Gb300 - GoKawiil

xAI plans to add 660,000 GPUs by December, reaching 1.44 million total

Elon Musk said xAI will bring 220,000 Nvidia GB300 GPUs online next week, another 220,000 in November, and potentially 220,000 more by late December. Combined with existing hardware at Colossus 1 and Colossus 2, this would give xAI about 1.1 million GB300 GPUs and 1.44 million GPUs in total. Musk also noted that Colossus 1, an inefficient mix of Hopper and Blackwell chips for training Grok, has been rented out to Anthropic for inference.

OpenAI details how its LLMs sped up design of Jalapeño AI chip

OpenAI has fully unveiled Jalapeño, its first AI accelerator chip, boasting up to 13.4 petaflops of 4-bit compute and 232GB of high-speed memory. The company says benchmarks show up to 3.6x lower latency than Nvidia's GB300 at lower power, and that the chip went from concept to silicon in under 20 months using its own large language models to accelerate design work with a team of fewer than 100 engineers.
