OpenAI & Perplexity

Perplexity now relies on GPT-6 Astra for end-to-end systems, using it to draft communications, modify software, and monitor production, checking in far less often than with earlier models.

ML Engineering

Deploying a churn model with FastAPI and Docker surfaces everything that breaks between "it runs" and "it's live."

Measurement

Estimating an opt-in AI feature's real impact requires selection-effect corrections when nobody randomized the rollout.
