We have been using sonnet 4.5 for sometime now, it's totally awesome and beats other models easily.
Been using this the last couple days via Cursor with great results! So much so that I made it the default model for my current launch.
I have been using Soneet 4.5 in Claude Code and Cursor since yesterday, and it is amazing!!
We're introducing Claude by Anthropic: a family of foundational AI models created to power safer, more reliable AI experiences.
Who is the best now?
Love that the model is now blending coding , reasoning and visualization . This makes it feel like true collaborator in the dev loop. Congrats on the launch @saaswarrior@kevin_garcia1@kyleturman@scott_white_sf
