Open AI releases 4.1
Published on April 15, 2025
Published on Wealthy Affiliate — a platform for building real online businesses with modern training and AI.
Available so far as an API. It has three models: 4.1, 4.1 mini and 4.1 nano
Each have a million token context, which is 8x that of 4o.
A little cheaper. 4o is $2.5 per million tokens in, $10 per million out. 4.1 is $2 in, $8 out
4.1 performs better than 4o
4.1 mini performs better than 4o mini
4.1 nano is there for quickie things and agents.
Not available yet through the UI, but I got this info from openrouter.ai and it's already available there.
More when I can try to use it...
