# Sam Altman publishes "Three Observations" on the economics of AI

On Feb 9, 2025 Sam Altman published "Three Observations". He argues that (1) a model's intelligence roughly equals the log of the resources used to train and run it, (2) the cost of using a given level of AI falls about 10x every 12 months, and (3) the socioeconomic value of linearly increasing intelligence is super-exponential. He concludes that systems that 'start to point to AGI' are coming into view and that agents will become virtual co-workers.

## Key facts
- Published Feb 9, 2025 on blog.samaltman.com; announced on X the same day
- Observation 1: intelligence ≈ log(resources: training compute, data, inference compute)
- Observation 2: cost of a given level of AI falls ~10x every 12 months (e.g. ~150x per-token price drop from GPT-4 early 2023 to GPT-4o mid-2024)
- Observation 3: socioeconomic value of linearly increasing intelligence is super-exponential
- Envisions that by 2035 anyone could marshal the intellectual capacity of everyone in 2025

## What happened

Altman set out a compact economic model of AI progress that explains the lab's huge infrastructure bets.

## Why it matters

It became a frequently cited framing for AI cost curves and investment logic in 2025–2026.
