# AI cost decline outpaces earlier technologies, but today's top models aren't necessarily cheaper

> The Decoder reports Epoch AI's estimate that AI prices fall about 13x per year once a fixed benchmark level is reached, citing about 3x annual algorithmic progress per MIT.

## Why It Matters

The Decoder's report frames rapid cost declines as a broad trend, while cautioning that reasoning models can use far more compute per task and that quality, speed, and error rate matter alongside price.

## Key Findings & Analysis

### What the numbers say

The Decoder reports that AI performance costs are falling faster than those of any previous technology, citing Epoch AI's measure of about a 13x-per-year price decline as AI hits a fixed benchmark performance level. After stripping out hardware gains and competition, MIT puts annual algorithmic progress at about 3x, according to the piece. It cautions that the trend does not mean today's best models are cheaper: reasoning models can cost more because they use far more compute per task.
