Underfiction的新消息
版本0.15.5
• 錯誤修正與穩定性改善。
Gemini Flash moves up a version
Gemini 3.8 Flash takes the Flash slot and stays the default story model — the same 1M context and the same rate per token as 3.7. It does think longer before it writes: measured on the same scenes, deep in a long chapter it spends about twice the hidden reasoning 3.7 spent for the same paragraphs, so the picker prices Flash at three credits per thousand characters instead of two. Turns already written on 3.7 keep its name in the log.
Half of the cheapest clip
MiniMax H3 Max Turbo joins the models you can animate on: the same five to fifteen seconds, the same 480p and 768p, sound on every clip, at half of H3 Max's price. Five seconds at 768p costs twelve credits, against twenty-four on H3 Max and a hundred and sixty-four on Grok. H3 Max keeps its place in the picker.
版本0.15.4
• GLM 5.2 與 Grok 4.6 加入推薦模型：最便宜的一回合，以及最少的拒絕。 • MiniMax H3 Max 以三分之一的點數，為短片配上聲音並讓它動起來。
A cheaper clip
MiniMax H3 Max joins the models you can animate on: five to fifteen seconds, 480p or 768p, sound on every clip, and well under half the price of anything else here that carries sound. HappyHorse leaves the picker in the same breath — MiniMax does its job for a third of the credits. Clips already animated on it keep its name.
版本0.15.3
• 把故事、人物或世界發佈到社群書架，也翻翻其他讀者放上去的作品。 • 說話，或 /敘述：引號讓一行成為對白，斜線負責調度場景，素白的文字仍是散文。 • 在 Roleplay 裡，對方的內心攤在頁面上；你的內心仍是你的。 • 你打好的開場，在 Story 與 Roleplay 之間切換也不會消失。 • 每筆資料都帶著建立日期，書架依最新排序。 • Android 上肖像搬出了書庫檔案：大書庫載入輕快，打字不再卡頓。
版本0.15.2
• 你書寫的欄位浮在正文之上，高度容得下一個段落。 • 圖片提示詞約一秒就到，一邊寫一邊落進欄裡。 • 要動畫化的圖片從架上挑：場景、人物、世界、你的照片。 • 在描述上方寫一行，其餘由它生成。 • 每個故事只有一種指示：寫下來、命名，到哪裡都能用。 • Grok 4.6 與 Gemini 3.7 Flash 就位，插圖改用 Grok Imagine 2。
Gemini Flash moves up a version
Gemini 3.7 Flash takes the Flash slot and stays the default story model — the same 1M context and the same rate per turn as 3.6, on a model Google built to hold a longer thread. Turns already written on 3.6 keep its name in the log.
Grok moves up a version
Grok 4.6 takes the Grok slot in the model picker, still set to write rather than deliberate. Illustrations get Grok Imagine 2, and Grok clips animate on Grok Imagine 1.5, which adds 1080p. Turns and images already made on the older versions keep their names in the log.
版本0.15.1
• 故事或角色扮演：在設定時選擇形式。角色扮演由一個人物開場，等你回應。 • 敘事控制會指明它的主語，第一人稱敘事者也保有自己的內心。 • 指示寫一次，任何故事都能用。儲存的指示會同步。 • 你的書庫會跟著你到每一部登入過的裝置。一個開關就能關閉同步。 • 在開場寫下之前，先為主角命名。
Grok is back in the picker
Grok 4.5 rejoins the model lineup, set to write rather than deliberate — it reaches the first line of prose in seconds. Kimi K3 leaves the picker; turns already written on it keep their name in the log.
版本0.15.0
• 五部經典加入書庫：《傲慢與偏見》、《簡愛》、《德古拉》、《勸服》、《福爾摩斯》。 • 書庫以世界與開場的展示開啟，並為手機重新打造。 • 挑選敘事方式，或寫下敘事者每回合都遵循的常駐指示。 • 附上圖片，敘事者就從所見之物寫起。 • 任何段落都能以你挑選的聲音朗讀。 • 單篇故事或整個書庫，都能匯出為可攜式 .underfiction 檔案。
The Library, rebuilt for the phone
The Library has its own shape on a phone now: a showcase that fits the width, a menu that sizes to its labels, and detail views with one clear way back. The navigation menu stays put on the pages it opens.
Credits read in your language
Credit amounts in logs, generation details, and top-ups are written in the language you are reading, on web, iOS, and Android.
Import says what went wrong
A character card or archive that will not open now names the file and the reason, instead of failing with one generic line.
Model rates on Android
The Android model picker shows what each model costs per turn, matching web and iOS.
Browse the openings on iPhone and Android
The starter browser is native now: page through the built-in worlds, their leads, and every authored opening without leaving the Library.
Directions, grouped at setup
Narration nudges are called directions, and story setup groups them into sections instead of one long list.
Duplicating a character keeps your place
Copying a character asks first and leaves the editor open, instead of dropping you back to the list.
Narration directions
Choose the voice before you write: First Person, Second Person, Present Tense, Inner Thoughts. The narrator holds what you pick for the rest of the scene, and scene summaries now keep that voice instead of pulling the prose back toward third person.
Standing directions
Give a story a direction in your own words — "keep her unreliable", "no dialogue tags" — and every turn follows it. It outlasts compression, travels inside portable archives, and comes along when someone takes the pen on a shared excerpt.
Four new openings in the original worlds
Pip, Syra, Lydia, and Lola each get an authored opening built on a shared secret or a craft rather than a stated romance. They lead their worlds in the library rail, and The Antler & Stone reaches the showcase for the first time.
Private or anonymized, stated plainly
Story and narration model pickers mark which models run inside Venice and which reach the model through anonymized routing. Hover a badge and it spells out what that guarantee covers.
Your library lives on your device
Stories, characters, and worlds are held locally, and nothing about them leaves the device unless you move it yourself. Portable .underfiction archives are how a story or a whole library travels between web, iOS, and Android.
One composer at every width
The prose composer uses a single compact layout from phone to desktop, and long speaker names no longer crowd out the field.
Steadier on every platform
Fixed iOS navigation dismissal and zoom transitions, web header and scrollbar shifts, Android segmented-control sizing, and a setup layout that moved while an animation ran.
The world showcase
The starter grids are now a moving showcase on the landing page and in every Library. Lead characters frame each world, the openings read like a table of contents, and the stage advances on its own until you touch it.
Straight into setup
Pick a world or a character and you land in story setup. The onboarding walkthrough and the separate persona step are gone.
Carry your whole library
Export everything — stories, characters, worlds, images, videos — as one portable .underfiction file, and import it on any other device. Merging keeps whichever copy of a story you edited last.
An empty shelf opens the Library
If you have not written anything yet, your shelf opens on the built-in worlds and characters instead of a blank screen.
The classics in eight languages
The complete classics collection — worlds, canon leads, and openings — is now localized in all eight supported languages.
A new landing page
Rebuilt around the showcase, with starting in the browser as the first move and the native apps a quieter link below it.
Five literary classics
Pride and Prejudice, Jane Eyre, Dracula, Persuasion, and Sherlock Holmes joined the built-in library on web, iOS, and Android — eight canon leads, new cover art, fifteen authored openings. You are not the protagonist by default: you take the governess's chair in Jane Eyre, Anne's position in Persuasion, and elsewhere you arrive beside canon as a confidante or a client.
Recommended models first
The story model picker opens on a clear first group of recommended models, with ratings and prices lined up down the list. Kimi K3 is back in the lineup.
Animate an image from earlier in the story
Any illustration already attached to the story can be the source when you animate a scene, not just the most recent one.
Illustrate and Animate, named the same everywhere
Media actions use the same labels and sit in the same place on web, iOS, and Android.
Stories follow your language
The prose language follows what you write, independent of the interface language. Switch mid-story and the narrator switches with you; keep going and it stays in the scene's language. The per-story language setting is gone, and interface language moved into Preferences.
World artwork on story cards
Story cards show the artwork of the world they belong to again.
Turn actions stay out of the way
Rerun, edit, share, and the rest stay quiet until you reach the passage they belong to.
A design pass across platforms
Tuned story setup, character editing, settings, navigation, and the input bar so web and iOS read as the same product at the same rhythm.
Write from an image
Attach an image to your next turn and the narrator writes from what it sees — a face, a room, a photograph you want in the scene. On web, iOS, and Android.
Read it aloud
Have any passage narrated in the model and voice you choose. Narration is cached on your device, so replaying a passage is free.
Export a story
Take a story whole, or stopped at any earlier turn, as readable Markdown or as a portable .underfiction archive carrying its characters, world, images, and videos.
Library actions in the toolbar
Import, export, and the rest of the library actions moved out of the page body and into the toolbar.
Clearer credit use
Credit spend rounds the way you would read it, and model pricing labels in story setup say what they mean.
Localized menus keep their labels
Fixed menu labels that fell back to English and a language switch that did not always take.
Opus 5
Upgraded Claude Opus from 4.8 to Opus 5 — a step up in long-scene coherence and prose control at the same price. Context window and credits-per-turn are unchanged; existing stories pick it up automatically.
Starter stories and Gemini 3.6 Flash
New starter stories on the landing page and in Library — curated openings you can step into with one tap, now on web, iOS, and Android. The library gained a Mine/Library switch so built-in material and your own work stay cleanly separated. Gemini 3.6 Flash joined the model picker and became the default story model.
版本0.14.4
• 重新生成一個回合時，你的其他版本會保留——取消、失敗或離開後都不會消失。 • 長場景續寫的花費更低、銜接更順，背景壓縮更聰明了。 • Kimi 重新加入陣容。 • 此外，還修正了一系列同步與生成的穩定性問題。
Shared story excerpts
Share a moment from any story as an unlisted link — a directive and the prose it produced, in a clean reader view. Readers can take the pen: one tap copies the full setup into their own library so they can continue the scene their way. Links are unlisted and never indexed; only you can share them.

版本0.12.2
Upgraded Opus from 4.6 to 4.7. Bumped the freedom rating on GPT and the quality rating on Gemini to reflect recent provider improvements. Fixed a credit-purchase webhook bug where some Stripe deliveries silently retried instead of posting credits cleanly on the first try.
版本0.12.1
Overhauled the credits experience with cleaner controls, a smarter default amount, and instant rendering of saved cards and auto top-up. Redesigned the landing page with a full-screen hero, prose sections, and a simplified world showcase. Fixed missing tab bars when navigating directly to /characters or /stories, and resolved a handful of hydration errors. Loading skeletons now match the actual content they replace.
版本0.12.0
Removed the mood system entirely — presets, prompts, and UI — to simplify story setup and let your prompts shape tone directly. Stabilized paragraph reveal during streaming so text lands smoothly. Improved the main menu, fixed a hero image flash on world open, an edit-last-turn bug, and assorted mobile polish issues.
版本0.11.3
Normalized spacing across galleries, modals, and page shells, and tightened touch targets on mobile. Switched to new generative cover art across the worlds.
版本0.11.2
Introduced shared typography, control, surface, and spacing token systems across the app for consistent rhythm and visual language. Refreshed the logo, favicons, and promo video, and polished the navigation icons.
版本0.11.1
Built-in worlds and characters are now immutable templates — editing one transparently clones it to your personal library on first edit, so the originals stay clean. Added a dedicated My Worlds section, made the Core sections collapsible, and refined character card defaults. Added a Sentry alert for missing Venice pricing so model gaps get caught before users hit them.
版本0.11.0

版本0.8.2
Rebuilt the core story runtime for reliability and lower token cost. Menu pages now open as overlays inside the story view so you never lose your place. Added mid-scene history compression to keep long conversations affordable, and introduced a free-tier framing for new users.
版本0.8.1
Fixed race conditions in the billing pipeline and library reconciliation. Patched a cross-user data leak, closed an auth bypass on system-generated content, and added missing database indexes. Improved cursor stability during streaming.
版本0.8.0
Introduced Patronage loyalty tiers with bonus credits on every purchase, and a configurable auto top-up so you never run dry mid-scene.

版本0.6.0
Worlds and characters now load from markdown content files — a single source of truth that's easy to author and version. Redesigned the landing page around worlds, characters, and creative freedom. Added per-world hero images and a mood system that shapes the AI's tone.

Dedicated Characters tab with portrait cards organized by world. Full-bleed character portraits in the edit modal. Separated built-in characters from your personal library so edits to one don't affect the other. Fixed hero image flicker on first world open.
版本0.5.1
Introducing Worlds — curated world settings with their own characters, lore, and narrative hooks. Four starter worlds ship out of the box: Ashworth End, Linden Park, Antler Lodge, and Marabou Syra. Each world generates dynamic scene suggestions via the LLM so every playthrough starts differently.
版本0.5.0
The platform has a new name and identity. What started as Fablis, then became Unreliable, is now Underfiction — a name that better captures what we're building. Added Sentry error tracking with full content redaction, and a pre-flight context window check to catch token overflows before they time out.
版本0.4.3
Published three launch-day posts covering why we built this, the case for local-first privacy, and what literary AI prose should actually read like. Enabled anonymous free tries so new visitors can start a story before signing up.
版本0.4.2
Generation now falls back to Grok when Venice hits rate limits, so you're never stuck waiting. Defaulted everyone to Opus with an 8k response length. Added loading skeletons, API caching, and entrance animations across the app.

New public landing page that showcases the platform to visitors. Unified all page headers into a shared PageHeader component and reworked logo routing. Replaced anonymous usage stats with per-user credit and usage data.

版本0.3.4
Five curated story presets — mainstream genres with pre-built characters and prose samples — appear on the dashboard for new users. Added an advanced settings section with editable system prompts for full control over the AI's behavior. Fixed a bug where the scene auto-generation never triggered.
版本0.3.3
Switched to full turn history instead of a truncated prose blob, giving the AI much richer context. Added optional example dialogue and style reference prose to character cards. Two-tier scene summaries: short for the sidebar, detailed for context injection.
版本0.3.2
Paper texture, upgraded drop caps, and scene ornaments give the reading view a tactile, book-like feel. Card hover animations, a streaming cursor, and prose reveal fades round out the mood. Also fixed the most persistent scroll-jump bugs during text reveal.
版本0.3.1
Full mobile-responsive pass with touch-optimized interactions and viewport fixes. Added SEO infrastructure: OpenGraph images, JSON-LD, sitemap, and robots.txt. New settings page with model picker, temperature slider, and max response length control.
版本0.3.0
Choose between roleplay, balanced, and novel prose styles — each shapes how the AI writes and responds. Mixed narration and dialogue input with distinct visual styling. Adaptive narration so the AI matches your writing cadence. Also added an in-memory story cache for instant page transitions.
版本0.2.2
Fork any conversation from any turn to explore alternate paths. New slash command menu: /as to switch character voice, /tone to shift mood, /newScene, and /narrate. Warmed up the color palette and added a subtle prose surface background.

版本0.1.0
The first working build of what would become Underfiction. Core story engine with AI-powered prose generation via Venice.ai, a reading view, character creation, and scene setup. Stories saved locally in the browser. Everything starts somewhere.
