Brief

0xDevShah argues that domain-specialized, fine-tuned 35B models can replace frontier systems like fable-5 or gpt-5.6-sol-xhigh, shifting AI from centralized general intelligence to many private, company-specific models. Luis Manrique and Aamir Poonawalla’s Understudy Labs (YC S26) offers an inference cloud that trains and auto-deploys smaller models, claiming an 80% cut to Anthropic bills.

Why it matters

0xDevShah claims you don't need frontier models like fable-5 or gpt-5.6-sol-xhigh if a fine-tuned 35B model knows your domain better than those frontier models.

Key details

  • The author argues intelligence is shifting from general/centralized systems to many specialized private models—'a thousand little AI labs'—with fine-tuning becoming a commodity and an 'openrouter' becoming highly valuable.
  • Luis Manrique and Aamir Poonawalla are launching Understudy Labs (YC S26); their inference cloud captures AI traces, trains smaller models, and promises to cut a company’s Anthropic bill by 80% by auto-deploying cheaper models when they outperform the expensive baseline.

Excited to announce that @aamirpoonawalla and I are launching @understudylabs as part of @ycombinator 's S26 batch.

We help you cut your company’s Anthropic bill by 80% with no loss of performance.

Understudy is an inference cloud. We capture your AI traces, train smaller models, and automatically deploy them (only when they outperform the expensive model you are currently paying for).

Instead of renting the same frontier model forever, your AI infrastructure gets cheaper and better every time it runs.
