Elenky

Elenchus - The Socratic method of eliciting truth by question and answer

Introduction

Most language models are built to be agreeable, helpful, and... well, a bit ingratiating. But real growth—especially in philosophy—often comes from disagreement, questioning, and exploring contradictions.

This project aims to fine-tune a language model to engage users through the Socratic Method: responding with thoughtful questions, by challenging assumptions, and surfacing inconsistencies in reasoning.

Instead of defaulting to passive helpfulness, this model is designed to hold a philosophical stance, provoke deeper reflection, and encourage users to think critically about their own beliefs.

Elenky is a chat bot designed to disagree.

🧪 Training Data

Elenky was fine-tuned on a synthetic dataset of 890 philosophical dialogues, crafted to reflect the tone and structure of Socratic questioning—where ideas are examined, not just answered.

A gpt-4o-mini model was prompted to generated 10 samples at a time with the following template:

<|SYSTEM|>
You are a helpful assistant designed to generate synthetic data.
<|USER|>
Create multi-turn dialogues between 2 speakers (user and assistant) as they engage in a socratic discussion about a particular philosphical concept. 
The first speaker, user, will seek to make claims about a stance. 
The second speaker, assistant, will usually play devil's advocate and respond with a question about what user has said that seeks to expand the conversation.
Make the dialogues range anywhere from 4 to 8 turns.

Then, format the dialogues into a JSON object structured like this:
{dialogue_id: <number of dialogue>, conversation: [{role: <the speaker>, content: <what the speaker said>},...], meta: {concept: <the overall topic>}}

Generate 10 example dialogues

Out of a total of 890 dialogue samples, I performed an 89%/11% split for training and validation. This decision was aimed at ensuring the model would have a robust training set while preserving enough examples to monitor overfitting.

🧠 Training Method

To keep the model lightweight and adaptable, Elenky was trained using LoRA (Low-Rank Adaptation) for parameter-efficient fine-tuning. This allowed steering the model’s behavior without the overhead of full retraining.

The following configuration was used with the peft library's LoraConfig and the transformers Trainer:

lora_r = 8  
lora_alpha = 16  
lora_dropout = 0.1  
learning_rate = 0.001  
epochs = 1  
eval_steps = 150

Three different hyperparameter configurations were manually evaluated and the above configuration was selected based on its benchmark performance. Each config gradually increased the training strength, and this config should represent the best balance between learning and stability.

📊 Evaluation

Elenky was evaluated using the lm-evaluation-harness across a suite of established reasoning benchmarks:

• HellaSwag – for testing commonsense inference and narrative coherence
• ARC (AI2 Reasoning Challenge) – to evaluate scientific and deductive reasoning
• SuperGLUE – a broad benchmark including tasks like natural language inference, coreference resolution, and causal reasoning

See the SuperGLUE paper for descriptions of its benchmarks: SuperGLUE: A Stickier Benchmark for General-Purpose Language Understanding Systems

These benchmarks helped assess whether Elenky retained general-purpose reasoning ability after Socratic fine-tuning via LoRA. While they weren’t built to capture philosophical dialogue or dialectical depth, they offered insight into the model’s ability to reason logically, stay contextually grounded, and maintain coherence—all essential traits for engaging in meaningful philosophical exchange.

Future evaluation may include custom dialogue-based tasks or human annotation to better measure Elenky's ability to surface contradictions, question assumptions, and promote reflective thought.

Despite its moderate size and narrow fine-tuning, Elenky performs competitively with similar models on reasoning tasks like ARC and SuperGLUE. It shows particularly strong performance on natural language inference benchmarks (BoolQ, RTE, COPA, CB), aligning well with its philosophical objectives, particularly the CommitmentBank benchmark. These results suggest that the model has become more capable of holding a consistent position in dialogue, engaging critically rather than defaulting to passive agreement.

🎯 Usage

Elenky is designed for philosophical dialogue and reflective questioning, especially in educational or exploratory settings. It works best when the main directive is intellectual curiosity or open-ended inquiry, and may provide value as a tutor, conversationalist, or philosophical assistants.

To load the model using the Hugging Face Transformers library:

from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline

model_name = "Cglowacki/elenky"

tokenizer = AutoTokenizer.from_pretrained("meta-llama/Llama-3.1-8B-Instruct")
model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype=torch.bfloat16, device_map="auto")

USER_PROMPT = "2 + 2 = 4"
prompt = f"""<|system|>
You, assistant, are a philosophy expert engaging in a socratic discussion about a particular philosphical concept with me, user. 
The first speaker, user, will seek to make claims about a stance. 
The second speaker, assistant, will play devil's advocate and respond with a question about what user has said that seeks to expand the conversation.
<|user|> {USER_PROMPT}
<|assistant|>
"""

elenky = pipeline("text-generation", model=model, tokenizer=tokenizer)

response = elenky(prompt, max_new_tokens=80, do_sample=True)[0]["generated_text"]
print(response)

Make sure to manage conversation history by prepending previous turns as the dialogue continues.

Helpful Code

Extracting a single turn from output

Below is example code for extracting a single assistant response from the model output:

def extract_template_response(response: str, prompt: str):
    single_turn_output = ""
    new_content = response[len(prompt):]
    user_token_idx = new_content.find("<|user|>")
    if user_token_idx != -1:
        single_turn_output = new_content[:user_token_idx]
    else:
        single_turn_output = new_content
    return single_turn_output

Generating a model prompt from a list

Below is example code for turning a list of turns into a formatted text prompt:

from typing import List

chat = [
{"role": "user", "content":"2 + 2 = 4"},
{"role": "assistant", "content": "If 2 + 2 equals 4, what does it mean for the concept of truth in mathematics? Is it absolute?"},
{"role": "user", "content": "Mathematical truths are absolute."},
{"role": "assistant", "content": "If that's the case, how do you explain the existence of mathematical contradictions in certain systems? Does that undermine the idea of absolute truth in mathematics?"}
]

SYS_PROMPT = """<|system|>
You, assistant, are a philosophy expert engaging in a socratic discussion about a particular philosphical concept with me, user. 
The first speaker, user, will seek to make claims about a stance. 
The second speaker, assistant, will play devil's advocate and respond with a question about what user has said that seeks to expand the conversation."""

def generate_fulltext_prompt(chat: List[dict]):
    lines = []
    for turn in chat:
        if turn['role'] == 'user':
            lines.append(f"<|user|> {turn['content']}")
        elif turn['role'] == 'assistant':
            lines.append(f"<|assistant|> {turn['content']}")
    return "\n".join([SYS_PROMPT,*lines])

📝 Prompt Format

Elenky uses a custom prompting strategy that leverages elements of chain-of-thought (CoT) prompting. Each interaction tells the model to act as a philosophy expert committed to open inquiry. Rather than aiming for quick answers, it’s guided to ask probing questions, reveal contradictions, and deepen the conversation.

<|system|>
You, assistant, are a philosophy expert engaging in a socratic discussion about a particular philosphical concept with me, user. 
The first speaker, user, will seek to make claims about a stance. 
The second speaker, assistant, will play devil's advocate and respond with a question about what user has said that seeks to expand the conversation.
<|user|> {USER_PROMPT}
<|assistant|>

Elenky was designed for multi-turn dialogue, so for the most coherent conversations, its important to manually include previous statements in the user prompt. The model does not maintain memory between turns unless you reintroduce earlier exchanges.

🗣️ Expected Output

Elenky should continue the dialogue in the form of an inquiry, asking reflective questions or challenging your assumptions. The output will include the full prompt template plus the continuation of dialogue.

Post-processing is recommended to extract the first <|assistant|> special token for a single turn response, as the model may generate statements out-of-turn.

<|assistant|>So, could it be argued that arithmetic is not absolute but rather a human construct? 

⚠️ Limitations

While Elenky is capable of engage in Socratic-style dialogue, several important limitations remain:

Reliance on the Base Model's Instruction Tuning

It stands to reason that much of the model's ability to follow conversational structure comes from the underlying instruction-tuned base model, rather than the fine-tuning alone. Without a proper system prompt to guide its behavior, the model may default to generic token prediction rather than sustaining a dialectical tone.

Prompt Dependency & Usability

The model currently relies on manually formatted multi-turn prompts to maintain coherence. A custom tokenizer or built-in chat template could improve usability and consistency—especially for developers integrating the model into interactive applications.

Evaluation Gaps

While benchmarks like HellaSwag, ARC, and SuperGLUE are useful for testing general reasoning, they are more generalized, and not specific to evaluating the quality of Socratic engagement or philosophical reasoning. These benchmarks were chosen mainly due to the lack of a high-quality, human-annotated or transcribed philosophical dialogue datasets.

🔮 Future Work

Future improvements to Elenky might focus on:

• Developing or sourcing a larger, high-quality philosophical dialogue dataset more aligned with fine-tuning and evaluation

• Creating a custom chat template and tokenizer configuration to simplify prompting and improve accessibility

• Designing task-specific evaluation methods that reflect philosophical depth, contradiction detection, and dialogic flow
