Primal-Mini-3B-Exp

Primal-Mini-3B-Exp is based on the Qwen 3B modality architecture, designed to enhance the reasoning capabilities of 3B-parameter models. It has been fine-tuned on a synthetic dataset derived from a subset of Qwen’s QWQ and DeepSeek R1, further optimizing its chain-of-thought (CoT) reasoning and logical problem-solving abilities. The model demonstrates significant improvements in context understanding, structured data processing, and long-context comprehension, making it ideal for complex reasoning tasks, instruction-following, and text generation.

Key Improvements

1. Advanced Reasoning & Logic: Optimized for multi-step problem-solving, logical deduction, and contextual analysis.
2. Fine-Tuned Instruction Following: Generates precise responses, structured outputs (e.g., JSON), and extended long-form text (4K+ tokens).
3. Greater Adaptability: Excels in role-playing, multi-turn dialogues, and diverse system prompts.
4. Long-Context Support: Handles up to 64K tokens and generates up to 4K tokens per output.
5. Multilingual Proficiency: Supports over 20 languages, including Chinese, English, French, Spanish, Portuguese, German, and more.

Quickstart with Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "prithivMLmods/Primal-Mini-3B-Exp"

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto",
    trust_remote_code=True
)
tokenizer = AutoTokenizer.from_pretrained(model_name)

prompt = "Explain the concept of logical reasoning in AI."
messages = [
    {"role": "system", "content": "You are an expert AI assistant specialized in reasoning and logic."},
    {"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=256
)
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]

response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(response)

Intended Use

• Advanced Logical & Analytical Reasoning: Designed for problem-solving, multi-step deductions, and cognitive reasoning tasks.
• Mathematical & Scientific Computation: Supports theorem proving, complex calculations, and scientific knowledge retrieval.
• Code Generation & Debugging: Generates optimized code, detects errors, and improves programming workflows.
• Structured Data Analysis: Processes tables, JSON, and structured formats for data-centric applications.
• Multilingual Reasoning & Translation: High proficiency across 20+ languages for international applications.
• Extended Text Generation: Capable of generating research papers, instructional guides, and in-depth reports.

Limitations

1. Moderate Computational Requirements: Requires mid-end consumer GPUs for optimal inference.
2. Language-Specific Variability: Performance may differ across supported languages, especially for low-resource languages.
3. Potential Error Accumulation: Long-form text generation can introduce inconsistencies over extended outputs.
4. Limited Real-World Awareness: Knowledge is restricted to training data and may not reflect recent world events.
5. Prompt Sensitivity: The quality of responses depends on the specificity and clarity of the input prompt.
