Weekly pricing news

Updated October 23, 2026
COMPOSITION

Mistral Large 4 replaces Large 3 at its list price

The launch discount ended on 20 October. The standing rate is well above Large 3's, but the new model scores far higher on the Artificial Analysis Intelligence Index.

COMPOSITION

MiniMax adds a Flash tier

M3.1 Flash sits beside M3 at half the price and outscores it, so the cheap end of the basket gets another strong contender.

PRICING

DeepSeek refreshes V4.1 Flash at the same price

A new checkpoint went live behind the existing endpoint on 17 October, lifting its score from 40 to 45 with no change to what developers pay.
