Anthropic Releases Fable 5.1 and Mythos 5.1
Anthropic launches Fable 5.1 and Mythos 5.1 with lower costs, fewer AI restrictions · businesstoday.in

Anthropic, a company that makes AI models, has released new versions called Fable 5.1 and Mythos 5.1.

These models are cheaper to use and have fewer restrictions.

They also do better on tests that measure how smart they are.

There's a new feature that lets businesses use these models on their own computers without sending data elsewhere.

The models have helped make some cool things, like a map of Venus.

Anthropic says these models are safer and less likely to do things they shouldn't, but they might be a bit more likely to help with bad things if someone asks them to.

They're also working on more safety features that will come out later this year.
