Changelog

Last week your cast got their close-ups with the introduction of Character Portraits. Now it's time to pull focus on the rest of your story world.

Image support is now available in your Story Bible's Worldbuilding section. The crumbling citadel, the neon-soaked night market, the cursed dagger that also speaks for some reason: you can now generate images straight from your Worldbuilding cards (or upload art you already have), so that every place and thing in your story has a consistent visual reference to match.

One-click generation

Like Character Portraits, Worldbuilding images can be generated with one click, no prompting required. Just select the thumbnail on any Worldbuilding card, choose a style (or four), and hit Generate. Your cards’ existing trait fields are used as reference. Want more control? Add details about the mood, lighting, angle, or whatever else you have in mind.

Your world, at a glance

Every image is saved to that card's gallery, so you can generate options and compare. Set your favorite as the card's thumbnail, and your Story Bible becomes a visual atlas of your world: something to glance at mid-scene when you need to remember where the dagger’s mouth even is.

Worldbuilding images are available now! We hope you'll share your favorites with us in our Discord community!

Barely a week after launching GPT-6 Sol, OpenAI is back with an upgrade: GPT-6.1 Sol is now available, and we've added it to Sudowrite.

OpenAI built this one to be even better at detail-heavy work, and says it makes about a third fewer factual errors than GPT-6 Sol on tricky prompts. For fiction writers, that shows up as better attention to your Story Bible details in longer Drafts. Early reviews of its prose are mixed, with some testers finding GPT-6 Sol's writing a bit more natural. (Try both on the same scene, and see which you prefer!)

GPT-6.1 Sol is available now in Write, Draft, and Plugins. Let us know what you think.

Claude Sonnet 5.5 launched today, and we’ve already made it available in Sudowrite. It's Anthropic's new mid-tier model, and it carries over some of the creative writing improvements we saw in Opus 5.5 (which we added last week). In our testing, it's about 30% faster and 30% cheaper than Opus 5.5.

We've also added several of the most-requested models from our community:

• Gemini 3.7 Flash and 3.8 Flash are Google's latest fast models. These brainy boys can handle a huge amount of text at once, which makes them great in Draft and especially strong in plugins that work across your full manuscript.

• GLM 5.3 is Z.ai's new flagship. It writes consistently solid prose and scores near the top of creative writing benchmarks. It's also one of the least repetitive models in testing, so try it for those long Draft sessions. GLM 5.3 Flash (formerly Ox Alpha) is the lighter, faster version.

• Qwen 3.8 Max is Alibaba's top model. Try it when you want a completely different-sounding voice on the page.

• Grok 4.7 is xAI's latest. Reach for it when you want strong prose that can handle no-holds-barred spice or violence.

Every model has its own strengths and weaknesses. Our goal is to make as many as possible available in Sudowrite, so you can find the right model for whatever it is you're working on. (Different pens for different pages!)

You'll find all these new models in the Prose Mode selector in Write and Draft, and in Plugins too. Let us know what you think, and which ones earn a spot in your regular rotation.
