ReasoningCore‑3B is a multilingual, reasoning‑enhanced large language model developed by EpitemeAI. Pretrained on vast amounts of publicly available data and instruction‑tuned to excel at nuanced reasoning, dialogue management, retrieval, and summarization tasks, it often outperforms many current open source and proprietary conversational models on a range of industry benchmarks. Fine tuned with reasoning dataset.

We used GRPO technique:

To provide a comprehensive overview of Group Relative Policy Optimization (GRPO), a post-training technique for Large Language Models (LLMs), and its application in the DeepSeek-R1 model.

Post-training with GRPO involves using a reinforcement learning (RL) technique to optimize the Large Language Model (LLM) after it has been initially trained.
GRPO specifically focuses on scaling test-time compute for extended reasoning tasks, making it suitable for tackling complex problems like mathematical problem-solving.
Unlike earlier methods that utilized search-heuristic approaches, GRPO relies exclusively on RL for post-training, thereby enhancing the model's ability to handle nuanced tasks.
The GRPO technique is available through the TRL library, and the Hugging Face Science team is working to reproduce the full DeepSeek-R1 training process, which can be explored in their

<reasoning>
...
</reasoning>
"""

Use with Transformers

Ensure you have transformers version 4.43.0 or later installed:

bash

pip install --upgrade transformers

import torch
from transformers import pipeline

model_id = "EpistemeAI/ReasoningCore-3B-RE1-V2B"
pipe = pipeline(
    "text-generation", 
    model=model_id, 
    torch_dtype=torch.bfloat16, 
    device_map="auto"
)
print(pipe("The secret to effective reasoning is"))

For Mathematical problems

Please use "Please reason step by step, and put your final answer within \boxed{}" in system prompt

Responsibility & Safety

Responsible Deployment

Approach:

ReasoningCore‑3B is a foundational technology that includes built‑in safety guardrails. Developers are encouraged to integrate additional safeguards tailored to their specific applications.

System‑Level Safety:

The model is designed to be deployed as part of a broader system that implements safety measures (e.g., Prompt Guard, Code Shield) to ensure outputs remain safe even under adversarial conditions.

Safety Fine‑Tuning & Data Strategy

Objectives:

Provide a reliable tool for building secure and helpful reasoning systems.
Mitigate adversarial misuse through advanced data selection and response optimization techniques.

Methodology:

Incorporate adversarial prompts during training to refine model refusals and response tone.
Combine human‑curated data with synthetic data.
Utilize iterative fine‑tuning using supervised learning, rejection sampling, and preference optimization.

Evaluations and Red Teaming

Scaled Evaluations:

Dedicated adversarial datasets were used to rigorously test the model’s robustness. Developers should perform context‑specific evaluations.

Red Teaming:

Experts in cybersecurity, adversarial machine learning, and responsible AI conducted recurring red team exercises to identify vulnerabilities and improve both performance and safety.

Critical Risk Mitigations

CBRNE:
The model has been evaluated to ensure it does not enhance capabilities for harmful activities involving chemical, biological, radiological, nuclear, or explosive materials.
Child Safety:
Expert assessments were conducted to evaluate and mitigate potential child safety risks.
Cyber Attacks:
Measures were taken to ensure the model cannot autonomously facilitate cyber‑offensive operations.

Ethical Considerations and Limitations

Core Values:

ReasoningCore‑3B is built on the values of openness, inclusivity, and helpfulness. It is designed to respect user autonomy and foster free thought and expression while mitigating potential harm.

Testing and Limitations:

Despite extensive testing across diverse scenarios, the model may occasionally produce inaccurate, biased, or objectionable outputs. Developers must perform additional safety testing and integrate further safeguards as needed.
