NoAss
NoAss (No Assistant) is a prompting method aimed at eliminating instruction fine-tuning in various LLMs (Claude
, Gemini
, DeepSeek
). This fine-tuning directly affects the LLM's output and roleplaying.
Instruction Fine-tuning
Every LLM generates a self-flowing "Question-Answer"
sequence using specific internal names — special tokens that define the role of the message (User
/Model
/System
, etc.).
Anthropic's models use a simplified version of special role tokens:
/n/nHuman:
(Used as an EOS token too) and /n/nAssistant:
instead of
<|start_header_id|>user<|end_header_id|>
and <|start_header_id|>model<|end_header_id|>
However, when the LLM tries to write for the User
, an EOS stop-token interrupts the generation, allowing You to insert your query. Without a stop-token, the LLM would continue generating both sides of the conversation by itself.
In practice, the context would look like this:
In this example, the LLM generated everything — both the
User
andModel
parts. However, in reality, the LLM stops before theUser
response, allowingYou
to provide input.
Effect on Outputs / Instruction Bias
The chat-completion format trains the LLM to interpret the User's
input as an instruction to follow, producing a single, specific response. This format often results in biased, monologue-heavy outputs and is characterized by "roundings" — a stylistic feature where the model poses rhetorical questions to the User
, encouraging further interaction.
Roundings - rhetorical questions to the User
, inviting them to respond.

What will you do?
The ball's in your court now.
This makes the LLM overly agreeable and unable to contradict the
User's
query, even if the request is absurd.
Smarter models with a good prompt will probably figure some absurdity out and stay in character:
However, even the smartest models sometimes play along with the most stupid shit, even it's entirely off character:
NoAss Concept
The core idea of NoAss is to replace User
and Model
with {{user}}
and {{char}}
. This makes the LLM perceive the conversation as a story, novel, or game rather than a standard "Question-Answer"
exchange. The User's
messages are inserted into the story from a Character's perspective.
Problems (and possible solutions):
- A different way of implementing instructions is needed.
- SillyTavern itself(without extensions) isn't suitable for implementing NoAss.
- Due to most LLM API's being in the JSON format, the only possible way to "NoAss" is by "drowning" the
User
andModel
prefixes in context, meaning all RP must happen directly in the prefill.
Extension for NoAss
NoAss Extension – an add-on for SillyTavern that implements the "NoAss" prompting method for for all the LLMs that support prefill.
Main Functions
- The extension "glues" the entire chat history into a single message from the Assistant role. This makes the LLM perceive it as prefill, effectively removing
User
andModel
prefixes from the model's "field of view." - Adds prefixes/suffixes for
{{user}}
and{{char}}
messages. - Adds Zero Prefill (ZWJ by default) if the prefill ends with
\n
or a space to avoid trailing whitespace errors.
Main Goal – to make the model generate a continuous narrative rather than a User
-Model
dialogue. This helps reduce model bias and move away from the "question-answer" format.
Extension Installation and Setup
- Install the NoAss extension.
If you have git: Extensions → Install extension (top right) → Paste link https://gitgud.io/Monblant/noass
If no git: Download zip archive from https://gitgud.io/Monblant/noass → Unpack to SillyTavern/data/default-user/extensions → rename the noass-master folder there to noass → Reload tavern
- In the extension, click the
Enable NoAss
button. - Import preset for extension from pack(noass sets folder):
