Sudowrite moves its Rewrite tool to an in-house model, Ballad
Sudowrite's September 22 release notes say moving the Rewrite feature to its own proprietary model, Ballad, cut error rates 30% and made authors 20% more likely to keep the AI's suggested rewrite.
Sudowrite's September 22 release notes say its Rewrite feature now runs on Ballad, the company's own in-house model, with Sudowrite claiming a 30% drop in error rates and authors 20% more likely to keep the resulting rewrite. The same update roughly doubled chat response speed, per the vendor's own notes -- treat those percentages as Sudowrite's self-reported figures, not independently verified. If you tried Rewrite before and abandoned it over quality, it's worth testing again before paying for a separate line-editing tool.
Why it matters to you: It's a workflow-level change -- not just a bigger third-party LLM -- for one of the most-used AI drafting tools among indie fiction writers.
