Sudowrite Release Notes

Last week your cast got their close-ups with the introduction of [Character Portraits](https://feedback.sudowrite.com/en/changelog/introducing-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 imag…

**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.**…

You’ve given your Characters names, aspirations, rich backstories, and probably even some undeserved trauma. Now you can give them faces too. **Character Portraits are now available in Story Bible.** Effortlessly generate impressive portraits directly from your character cards or upload images you already have, to maintain a persistent visual reference for each character. \*\*From description to portrait** Portrait generation uses your character’s existing **Physical Description**, so there’s no need to write a separate image prompt. Open a character card, click the empty **Portraits** box, choose a style, and click **Generate**. We’ve included four default styles: **Painterly**, **Cinematic Realism**, **Bright Editorial**, and **Storybook**. Pick one, or select all four to generate different variations at once. Your brooding antagonist might look surprisingly charming in Storybook. **A little art direction** Want a particular outfit, expression, or setting? Add instructions i…

It was a big day in AI. Three bleeding-edge models landed today—**Anthropic's Claude Opus 5.5 and OpenAI's GPT-6 Sol and GPT-6 Luna. All three are now in Sudowrite.** - **Claude Opus 5.5** is the first model in Anthropic's new Claude 5.5 family. Anthropic says it performs at the level of Fable 5.1 on most work, while running more than 30% faster than Opus 5. Anthropic says the writing is clearer, follows instructions more closely, and as one early tester told them, "it writes the way I do." - **GPT-6 Sol** and **GPT-6 Luna** round out OpenAI's GPT-6 family below Astra. Sol is super smart and makes about half as many *factual* *whoopsies* as its predecessor—making it great for Story Bible adherence and a solid choice for Plugins. Luna is the quick, inexpensive choice: useful for lots of shots on goal, brainstorming… anything where you want to generate a lot and sort it out afterward. - **Each of them uses fewer credits than the model it replaces.** In early side-by-side runs on the same passage with the same inputs, GPT-6 Sol came in around 40% cheaper than GPT-5.6 Sol, GPT-6 Luna around 10% cheaper than GPT-5.6 Luna, and Opus 5.5 just barely cheaper than Opus 5. There’s a big gap between these models though, with Sol at roughly a third of Opus 5.5's credit cost, and Luna at about a seventh. That’s a lot of numbers for a site about words though, and what matters is what you think of their prose. **All three are available now in Write, Draft, and Plugi…
