According to @StockMKTNewz, Nvidia (NVDA) posted that "Space isn’t just for stars anymore … Starcloud’s H100-powered satellite brings sustainable, high-performance computing beyond Earth" on Oct 22, 2025. According to @StockMKTNewz, the post explicitly highlights Starcloud, the H100 GPU, and space-based AI computing under the $NVDA ticker. According to @StockMKTNewz, the post contains no cryptocurrency references.

According to @karpathy, nanochat is a minimal from-scratch full-stack pipeline that lets users train and serve a simple ChatGPT-like LLM via a single script on a cloud GPU and converse with it in a web UI in about 4 hours, enabling an end-to-end training and inference workflow. source: @karpathy. He specifies the codebase has about 8,000 lines and includes tokenizer training in Rust, pretraining on FineWeb with CORE evaluation, midtraining on SmolTalk and multiple-choice data with tool use, supervised fine-tuning, optional RL on GSM8K via GRPO, and an inference engine with KV cache, Python tool use, CLI, a ChatGPT-like web UI, plus an auto report card. source: @karpathy. Disclosed cost and timing benchmarks are about $100 for roughly 4 hours on an 8x H100 node and about $1000 for about 41.6 hours, with a 24-hour depth-30 run reaching MMLU in the 40s, ARC-Easy in the 70s, and GSM8K in the 20s. source: @karpathy. From these figures, the implied compute rate is roughly $3.1 per H100-hour (about $100 across 32 H100-hours) and about $3.0 per H100-hour at the longer run (about $1000 across 332.8 H100-hours), providing concrete GPU-hour cost benchmarks for trading models of AI training spend. source: @karpathy. He also notes that around 12 hours surpasses GPT-2 on the CORE metric and that capability improves with more training, positioning nanochat as a transparent strong-baseline stack and the capstone for LLM101n with potential as a research harness. source: @karpathy. For crypto market participants tracking AI infrastructure, these cost-performance disclosures offer reference points to assess demand for centralized cloud and decentralized GPU compute tied to open-source LLM training workflows. source: @karpathy.

According to @hyperbolic_labs, the H200 GPU provides 141GB of HBM3e memory, a 76% increase over the H100’s 80GB, enabling training of larger models and processing more data with fewer slowdowns from memory swapping, source: @hyperbolic_labs. For trading analysis, the cited 141GB on-GPU memory capacity and 76% uplift are concrete specs that reduce swapping bottlenecks during AI workloads and serve as trackable inputs for AI-compute demand narratives followed by crypto-market participants, source: @hyperbolic_labs.

According to @hyperbolic_labs, NVIDIA’s H200 delivers up to 1.9x faster large language model inference versus the H100, and the source emphasizes this latency gain is crucial for production environments where response time matters (source: @hyperbolic_labs). According to @hyperbolic_labs, the highlighted low-latency advantage directly targets production-grade generative AI workloads that demand rapid inference (source: @hyperbolic_labs).

According to @hyperbolic_labs, its H100 systems sustained the most demanding workloads for a full week with no interruptions during massive parameter optimization runs, delivering consistent performance from start to finish, source: @hyperbolic_labs on X, Aug 21, 2025. For traders, the key datapoints are seven days of continuous operation, zero interruptions reported, and consistency under heavy optimization workloads, evidencing operational stability as presented, source: @hyperbolic_labs on X, Aug 21, 2025. No throughput, latency, cost, or power metrics were disclosed in the post, limiting direct performance-per-dollar comparisons at this time, source: @hyperbolic_labs on X, Aug 21, 2025.
