  1. Readable on your devices only.

    Your conversation is readable on your device, and on your other devices if you sync them. Nowhere else.

  2. Unreadable to us.

    Your message passes through without being written down; your chats are only ever stored encrypted.

  3. The model doesn’t know you.

    It gets the question, never your email, your account or your IP address.

  4. Nothing is left along the way.

    The reply comes back and is stored here, encrypted; even when you sync, your key never reaches us in the clear.

What it is

Euryale 70B is an open model published by Sao10K and tuned for one job: playing characters and writing fiction with them. On NeverNo it runs as a private model, on providers chosen for not keeping requests, and your conversation history stays encrypted in your own browser. Nobody at NeverNo reads your scenes, and your account is never attached to what you write.

Where most assistants answer a question and stop, Euryale is happiest inside an ongoing scene. It takes a persona, holds a tone, describes a setting and lets the other characters react, which makes it a natural partner for the characters you create in NeverNo or for an interactive story you steer turn by turn. It answers frankly and without arbitrary refusals, including dark or difficult fiction, within NeverNo's hard limits.

It is a direct model: it does not reason before writing, so the first words arrive almost at once. In our own test of November 4, 2026 (12 conversations of 3 turns, measured from our client), its median time to the first word was 0.45 s, versus 1.2 s for DeepSeek V4 Pro and 2.9 s for GLM 5.2 in the same run. Euryale 70B is included in every paid plan, under the daily message quota, with no credits to spend.

Choosing it is mostly a question of genre, whether horror, science fiction, fantasy, westerns or noir. If you want prose with atmosphere, banter between rivals, a mystery that unfolds over an evening or a companion who remembers what you told them an hour ago, Euryale is the specialist. If you need facts checked, a document summarized, a bug fixed or a plan argued through, switch to a reasoning model such as GLM 5.2 or DeepSeek V4 Pro, both also included in paid plans, and come back to Euryale when the story resumes.

Strengths

  1. Built for roleplay: it stays in character, speaks in the persona's voice and keeps the details of a scene consistent over a long exchange.

  2. Fast replies: a median of 0.45 s before the first word in our November 4, 2026 test, which keeps a back-and-forth scene fluid.

  3. Private by design: an open model run by NeverNo on providers that do not keep requests, with your history encrypted in your browser.

  4. A 128k-token context, enough to carry a long story, a detailed character sheet and the rules of your world in the same conversation.

Limits

  1. Each reply is capped at 4,096 tokens: very long chapters come in several turns rather than in one block.

  2. It does not read images and does not reason step by step; for analysis, math or code, GLM 5.2 or DeepSeek V4 Pro are better picks.

  3. It is tuned for scenes and role-play; for the frankest answers, NeverNo Uncensored is the model tuned for that.

  4. It is not on the Free plan: it comes with paid plans.

When to choose it

  • Playing a character you designed

    Give Euryale a name, a personality, a way of talking and a backstory, and it will answer as that person for hours. Useful for companion characters, a game master for a solo campaign, a sparring partner for dialogue practice or a rehearsal of a difficult conversation with a stubborn boss, a nervous witness or a sarcastic detective.

  • Co-writing interactive fiction

    You describe what your protagonist does, Euryale narrates the consequences and voices everyone else. The story moves at your pace, branches wherever your choices lead, and nothing you write is stored on our servers. If a twist disappoints you, simply say so and ask for another outcome.

  • Drafting dialogue and scenes for a novel

    Ask for the confrontation between two characters, the same scene from another point of view, or ten lines of banter in a given register. Its speed makes it easy to try several versions and keep the best, then polish the chosen draft yourself or hand it back for another pass with sharper instructions.

Prompt tips

  1. Open with a short character sheet: who the character is, how they speak, what they want and what they would never do. Euryale follows a clear persona far better than a vague one.

  2. Set the frame of the scene in the first message (place, time, point of view, length of replies), then stay in the story: it keeps the rhythm you establish.

  3. If a long session starts to drift, sum up the key facts in a single line and ask it to continue from there; it picks the thread back up cleanly, names, grudges and unfinished quests included.
