  "title": "The economics of AI distillation: prices, training costs, and the market shocks",
  "updated": "2026-09-03",
  "summary": "Distillation is, at bottom, an arbitrage: the capability embedded in a $40M-$500M frontier training run can be harvested through an API for a four- or five-figure query bill and re-trained into a small model for hundreds of dollars. That asymmetry is now visible in published price lists, where the gap between a vendor's flagship and its small tier runs 10x to 42x on output tokens, and in the research record, where Sky-T1-32B was distilled for under $450 and s1-32B for a reported ~$50. It became a macro event on 27 January 2025, when DeepSeek-R1 and its six open-weight distilled students wiped $589B off Nvidia's market capitalisation in a single session - the largest one-day loss in stock-market history - and it became a policy event in February 2026 when OpenAI told the House Select Committee on China that DeepSeek was running obfuscated distillation pipelines against its models. The counter-trend matters too: Epoch AI measures inference prices for a fixed capability level falling 9x-900x per year, which compresses the payback on self-hosting a distilled model to the point where, on our own TCO model, a single-GPU deployment only beats Claude Haiku 4.5 above ~658M output tokens a month and never beats the cheapest serverless open-model endpoints. And in August 2026 DeepSeek reversed the race to zero, raising V4 API prices by as much as 1,100% and introducing peak/off-peak rates - the first major signal that ultra-cheap distilled inference was being priced against capacity, not against marginal cost.",

The last two exceed single-GPU capacity, so at these prices a one-GPU deployment never pays back against the cheapest hosted endpoints. Excludes the one-off distillation cost ($450-$40,000, see other tables), redundancy, and the fact that measured self-hosted cost per output MTok on identical H100 hardware spans $0.21 to $15.25 depending purely on request concurrency.",
