SOXL sinks 25%, Anthropic's junk-rating snag, and the 1,024-GPU parallelism question

Chips get crushed, Anthropic's IPO hits a credit snag, and we coach you through a classic distributed-training interview question. Markets: SOXL -24.75% to $77.05, QQQ -3.47% to $690.49, VGT -4.32% to $116.96, VUG -3.00% to $85.06 for the week. AI news: A Blackstone forecast reported by the FT says Anthropic, fresh off its S-1 filing to list as ANT, will likely get a high junk credit rating, making it costlier to borrow for compute. Interview Tip of the Day: You have 1,024 GPUs to train a 70B model. How do you choose between data, tensor, pipeline parallelism and ZeRO/FSDP sharding, what does each split, where does the communication cost land, and why does tensor parallelism usually stay inside one node? Did You Know: Alan Turing's 1950 paper asking Can machines think? and the birth of the Turing test. Questions or feedback: [email protected]
