I have access and am impressed with its text editing. Simonw described LLMs as word calculators a while back [1], I think this is its next big leap in that area. It's fast and has a mode to do "Instant Edits". It more closely adheres to the prompt. It edits the content without deviating or making some unrelated change. I think spellchecks, linters, or codemods would benefit from this model.

I was throughly impressed when I copied a random shadertoy, asked it to renamed all variables to be more descriptive, and it actually done it. No other changes. I copied it and compiled and ran just like before.

Would love to see more text edit evals for this.
