B300 GPU rental prices are up 106% since mid-July. B200 rental prices are up 66% H100 rental prices are up 17% over the same period. Average token prices are down 58% since mid-July.

NVIDIA B300 servers retail around $350k min, crazy power/cooling requirements/etc. (bad maths) per GPU (8) is $43,750, if you can even find them (narrator: you can't) then pay for collocation etc... 9 PFLOPS dense FP4. DGX Spark: $4700, plug in anywhere, 1 PFLOP (fp4 sparse). B300 9ish PFLOP dense FP4 super expensive impossible to collocate anywhere etc. etc., $4861.11 per PFLOP. DGX Spark $4700 plug in any 15 amp outline in any house, $4700/PFLOP (but sparse). Memory is slower, so I guess use less of it/less manipulation of it... Yep, math checks out - pretraining on decentralized DGX Spark with native sparse FP4 (checks notes: yes we're using ternary weights which slot perfectly into sparse FP4 compute) should be a thing. Time to test it out...

10,000 @nvidia B300 GPUs. India's largest AI Factory. Together AI and @larsentoubro are building the country's biggest GPU cluster, backing open-source inference, fine-tuning, and training at scale for India's AI-native ecosystem.

The Compute Desk Nvidia B300 GPU-hour index is at its all-time high. As margins on training grow thinner, neoclouds are collectively shifting focus to inference. High-priced B300s are generating ROI by lowering the marginal cost per token generated through batch inference.

MTP3 was checked alongside the baseline on B300 DEP8: AIME25: 0.9500 → 0.9667 GPQA: 0.9268 → 0.9242 OCRBench: 0.896 → 0.895 Two validation rounds completed with zero request errors. These are results from the tested build, not a claim that final-release validation is complete. 4/6

$IREN achieved all of this in 2026: - NVIDIA Exemplar Cloud for B300s and GB300s - NVIDIA-certified hypervisor through Mirantis - Customers like Microsoft, NVIDIA, a frontier lab, Figure, Prometheus, Perplexity, Fluidstack, Cohere... How can you not admire these achievements?

Interesting that $NBIS is showing $0.99 pricing for B300s The explanation? A temporary supply-demand imbalance “When we launch new regions, the increase in available capacity drives prices down.” — Nebius CTO
