Leaked OpenAI slides: ChatGPT tops 1B weekly users, compute grows 10X every two years

firstadopter shared slides from OpenAI's talk at OCP Global Summit 2026, citing the claim that "compute is increasing by 10X every two years" and "needs optics to continue."
Key takeaways:
- AI at Work: ChatGPT weekly users grew from 700M (Sep 2025) to over 1B (Aug 2026); Codex weekly users jumped from 1.6M to over 5M; 75% of surveyed workers reported better output speed or quality with AI.
- New benchmarks: GPT-6 Astra vs. GPT-5.6 Sol — Automation-Bench workflows 13.1%→41.4%, Terminal-Bench 4.0 coding 37.3%→57.9%, Terminal-Bench Science 0.1 at 64.6%.
- Metrics that matter: OpenAI argues inference should be compared via request latency (TTLT) and energy per request (tokens/joule) across the full Pareto frontier, explicitly rejecting chips-used and per-chip throughput as goals.
