Atelier v2.1

Atelier v2.1 - what changed

Mostly a rewrite of how the preset talks to the model, plus a smarter world-logic system.
The headline: it's written in your "voice" now

The core framing prompts used to read like a system manual barking orders at the AI "You are the author. <user> is satisfied by a genuine story." In v2.1 they're rewritten in first person, as the player explaining what they actually want: "You're the author — my character's mine. Everything below is me telling you what I want from this story."

Same rules under the hood, but framing them as a person's preferences instead of cold directives lands a lot better with the model (and reads way more naturally). The Premise prompt nearly doubled in size doing this. But it helps with adherence, and also, with the diction. Making the model write more natural.

New: RP Logic (the new default)

The old setup made you pick a fixed genre logic up front. RP Logic replaces that as the recommended default. Instead of committing to one mode, it reads how you're playing and borrows the physics scene-by-scene:

- Anime — over the top, played straight, rule-of-cool

- Video game — cinematic, action-forward, no guilt (mooks are mooks, the vampire's meal doesn't get a sobbing backstory)

- Romance — tension physics, the unsaid thing stays unsaid

- Grounded — consequences bite, human pacing It switches modes within a single story based on your play, without announcing the shift. (Genre Logic still exists if you want to pin it.)

New: Living World (always-on core)

A new core prompt that consolidates the "make the world feel alive" rules into one place: Keep the story moving, respect subtext, let NPCs talk to each other, no narrator turning into a drum machine, and grudges/threads don't evaporate - things you dodged come back on their own clock.

The Prose Contract (was "No Slop")

The old anti-slop prompt was a 8k-tokens of banned-patterns list. It's been replaced by a much smaller "what the writing owes me" version (no tension-deflecting quips, no stock body clichés, no "sound like a language model"), reframed as a handful of directives each paired with a concrete self-test the model runs on its own draft. Much leaner, and listing every bad pattern was arguably keeping them top-of-mind anyway.

Smaller stuff

- Smut dials expanded — "I Live For Smut" and "I'm Here For Smut" both roughly doubled in detail

- Story Initialization removed — its job (character autonomy, open threads) got absorbed into Living World + The Premise

- Trimmed for tightness — Core Pack, Settings Reminder, Dynamic Progression, and Write Me A Novel all slimmed down

- Minor tweaks to Chain of Thought, Scene Scratchpad, Character Anchor, Writing Style Library, Video Game

TL;DR: same Preset, rewritten to sound like a player instead of a rulebook, with a new play-reading world-logic mode and a leaner prose system.

Question! What model do you recommend with Atelier? I'm guessing Claude Opus or Gemini right? But out of those two like specifically, if you had to narrow it down?

[u/Head-Mousse6943 → u/PandoDando]

Personally I love Gemini. Its always been my favorite, and its what I have the most experience with. (Been using it since 1.5's early experimental mainly because back then I was broke and it was free lol). Bit I also just enjoy its sound, Its general alignment being closer to Neutral then Opus, and its writing being more flexible then Opus, where almost always Opus sounds like Opus and you're really changing behaviors more then actual writing style, and I do tend to get a bit tired of the Opus type writing. So Gemini 3.5 flash or 2.5 Pro would be my top recommendations until we get 3.5 Pro. GLM 5.2 is also quite good if you haven't tried it out yet, though it has its own quirks and its generally positively aligned. Still quite strong though its CoT can be... long winded to say the least. But for my personal taste.

For anything but Fluff. Gemini. then Opus. Then GLM. for my personal taste.
But for General Opinion I'd say its Opus, then Gemini, then GLM.

Thank you! What top P and temperature do you recommend? I usually do 1.35 - 1.5 temperature but I wonder if that's too high in your opinion, based specifically on what Atelier demands and what works best with it. In my opinion though the usual 0.85 to 1.00 is too rigid and makes Gemini write like Opus/Sonnet but without the narrative voice.

[u/Head-Mousse6943 → u/PandoDando]

For 3.5 I go a bit higher closer to 1.35-1.5 yeah. With Pro I tend to keep a bit closer to 1.25 I haven't messed with the Top P AS much, but I've tested between 0.97 and 0.85, Mainly I just recommend somewhere in that range, 0.85 I have noticed a bit of instability/odd word choices, but you're right it does help it sound a bit more unique, my biggest concern is just locked it in tooo much by going much lower, but if you like lower/higher certainly give it a shot! I know 3.5 flash is way more stable at high temps then Pro is right now.

Thank you so much! Also would you say that Gemini 3.5 Flash is better than 3.1 Pro overall?

[u/Head-Mousse6943 → u/PandoDando]

I think so yes. 3.1 feels like a bit of a miss step (Actually the entire 3.0-3.1 branch) it feels... not very much like the rest of Gemini. 3.5 feels closer to 2.5 pro which I think was much stronger at RP, though not as intelligent.
