I've tested Claude Fable 5.1 over the last week. Everyone should try this model. If you're a beginner, if you're a seasoned professional, if you use it for coding or anything else, this model is delight to work with and has the depth of the Fable models. I really trust this model and it really feels like you are working with a human collaborator. If you have not tried Fable or didn't like it, try it again. It's amazing.
