# **Primus-Optima-QwenKV-1.54B**
|
|||
|
|
|
|||
|
|
> **Primus-Optima-QwenKV-1.54B** is an **experimental chain-of-thought reasoning and code generation model**, built by combining the strengths of two sources:
|
|||
|
|
>
|
|||
|
|
> - **DeepSeek R1 (distilled 1.5B)** for strong math and coding reasoning.
|
|||
|
|
> - **Qwen2.5-0.5B**, fine-tuned with **Process Reward Models (PRM)** to boost structured step-by-step outputs in math and logic.
|
|||
|
|
|
|||
|
|
This hybrid design results in a **bilingual, high-precision model** with enhanced **reasoning depth**, **multi-step clarity**, and **lightweight adaptability** for math and code applications.
|
|||
|
|
|
|||
|
|
## **Key Features**
|
|||
|
|
|
|||
|
|
1. **Chain-of-Thought Reasoning for Math + Code**
|
|||
|
|
Designed to produce human-like intermediate steps in both math and programming problems — useful for education, tutoring, and technical assistants.
|
|||
|
|
|
|||
|
|
2. **Hybrid Architecture (Reasoning + Reward-Guided Fine-Tuning)**
|
|||
|
|
Combines **DeepSeek R1’s** distilled capabilities with **Qwen2.5-0.5B**'s reward-optimized reasoning for structured, goal-driven outputs.
|
|||
|
|
|
|||
|
|
3. **Multilingual Capabilities (English + 中文)**
|
|||
|
|
Fluent and accurate in both English and Simplified Chinese, making it suitable for diverse learning and development environments.
|
|||
|
|
|
|||
|
|
4. **Coder Experimental Mode**
|
|||
|
|
Able to solve algorithmic tasks, complete functions, and offer code walkthroughs using the same step-by-step format as it does for math.
|
|||
|
|
|
|||
|
|
5. **Lightweight Yet Capable (1.54B)**
|
|||
|
|
With just 1.54B parameters, it is efficient for local deployments while offering surprisingly strong performance on STEM and programming tasks.
|
|||
|
|
|
|||
|
|
## **Quickstart with Transformers**
|
|||
|
|
|
|||
|
|
```python
|
|||
|
|
from transformers import AutoModelForCausalLM, AutoTokenizer
|
|||
|
|
|
|||
|
|
model_name = "prithivMLmods/Primus-Optima-QwenKV-1.54B"
|
|||
|
|
|
|||
|
|
model = AutoModelForCausalLM.from_pretrained(
|
|||
|
|
model_name,
|
|||
|
|
torch_dtype="auto",
|
|||
|
|
device_map="auto"
|
|||
|
|
)
|
|||
|
|
tokenizer = AutoTokenizer.from_pretrained(model_name)
|
|||
|
|
|
|||
|
|
prompt = "Write a Python function to compute factorial using recursion."
|
|||
|
|
messages = [
|
|||
|
|
{"role": "system", "content": "You are an expert tutor in math and programming, explaining step-by-step."},
|
|||
|
|
{"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=512
|
|||
|
|
)
|
|||
|
|
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]
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## **Intended Use**
|
|||
|
|
|
|||
|
|
- **Math & Programming Tutors**: Assist students with logic-driven step-by-step explanations.
|
|||
|
|
- **Bilingual STEM Apps**: Ideal for dual-language math or coding environments.
|
|||
|
|
- **Competitive Reasoning Tools**: Suited for reasoning-intensive tasks like Olympiad prep, technical quizzes, and programming challenges.
|
|||
|
|
- **On-Device LLMs**: Lightweight enough for web or embedded applications needing real-time reasoning.
|
|||
|
|
|
|||
|
|
## **Limitations**
|
|||
|
|
|
|||
|
|
1. **Experimental Nature**:
|
|||
|
|
This is a hybrid research model; performance may vary across general or creative domains.
|
|||
|
|
|
|||
|
|
2. **Size Constraints**:
|
|||
|
|
As a 1.54B parameter model, extremely complex reasoning tasks may challenge its capabilities.
|
|||
|
|
|
|||
|
|
3. **Bias & Generalization**:
|
|||
|
|
Inherits biases from both DeepSeek R1 and Qwen2.5. Use caution in high-stakes or sensitive applications.
|
|||
|
|
|
|||
|
|
4. **Prompt Engineering Required**:
|
|||
|
|
Structured prompts with clear questions yield the best results, especially for multi-step problems.
