The various AI models available today all have different strengths. Some write prose with flair, some have the ability to take instructions well, and some are simply brilliant. Others are fast and cheap and reliable enough, like a No. 2 pencil.

On Thursday OpenAI launched GPT-4o Mini, an incredibly cost efficient mini model. It's fast, cheap, and beats both GPT-3.5 Turbo and Claude 3 Haiku in OpenAI's benchmark testing. In our testing it used half the credits of Haiku and 10x fewer than GPT-4o proper. As for the quality of its prose, well, that's for you to decide.

GPT-4o Mini is now available in your Write Settings, Chapter Generator, and Plugins. Give it a spin, and let us know what you think of it in our Discord.
