Modal CEO Erik Bernhardsson says the team once discussed shutting down sandboxes, its service for running AI-written code. They now bring in about a third of revenue. He expects agents to move toward brief, snapshotted environments.
Modal CEO Erik Bernhardsson says GPUs are mostly sold as fixed multiyear blocks, while real demand rises and falls. After a $750 million raise, he argues that pooling thousands of customers lets Modal resell that capacity in flexible slices.
Investor Chamath Palihapitiya argued that AGI exists but can't spread until power and data centers are built, and predicted a compute shortage within three or four years. Alex Wissner-Gross countered that demand and smaller models matter too.
Evan Conrad, CEO of SF Compute, says delivering traded GPU time made his firm do a cloud's work, yet it owns no chips because that would let it manipulate prices. He argues NVIDIA and big clouds couldn't run such a market neutrally.
SF Compute CEO Evan Conrad argues that GPU time is too varied to trade as one uniform commodity. He says cash-settled contracts and price indexes should be built on markets that actually deliver compute, or they risk manipulation and poor hedges.
Thomas Sohmers, co-founder of AI chip company Positron, says GPT-6 Astra and Opus 5.5 agents now run its chip tests on emulators in a closed loop. He says the company's token spend briefly exceeded its human salaries and peaked above $100,000 a day, and the agents have not yet had a novel design idea.
Positron CTO Thomas Sohmers said AI agents are multiplying demand for memory. He claimed Positron's first-generation product sustained 93% of theoretical memory bandwidth, against an average of 30–40% for NVIDIA GPUs when decoding with transformer models. Its next chip, Asimov, is planned for 2027.
Epoch AI estimates that AI memory shipped through 2027 could run 30–170 million frontier agents at once if fully devoted to them. That matches workers' hours, not their output. On Moonshots, Dave Blundin called memory AI's bottleneck.
MIT PhD student Alex Zhang said AI generates nearly all recent GPU Mode leaderboard solutions, yet one expert's AI-steered kernel was essentially the only top-10 entry stable end to end. He argues experts remain strong verifiers.
Steve Hou of Silicon Data said big clouds charge at least two to three times neocloud GPU rates for bundled services. He guessed a recent rise in its token index reflects which models people use, not price hikes.
H100 rental prices rose 22% in a month to $3.28 per GPU-hour on Ornn's transaction index. Dave Blundin, whose fund backs Ornn, called it a reversal of chip depreciation; Emad Mostaque said better models make old Hoppers more useful.
DeepSeek says V4.1-Flash's KV cache needs a quarter of the HBM and an eighth of the SSD cache of its prior generation. Moonshots panelists argued that changes what AI data centers should buy; one estimated HBM is 40% of US buildout spending.
