# **BetaCeti-Beta-4B-Prime1** |
|
|
|
|
|
> **BetaCeti-Beta-4B-Prime1** is a compact, coding-optimized language model built on the **Qwen3-4B architecture**, tailored for high-accuracy **code generation**, **debugging**, and **technical reasoning**. With **4 billion parameters**, it strikes a balance between performance and efficiency, making it an ideal assistant for developers, educators, and engineers working in constrained environments or requiring fast inference. |

## **Key Features** |
|
|
|
|
|
1. **Qwen3-4B Architecture Core** |
|
|
Built on the robust and scalable **Qwen3** transformer backbone, offering strong performance on both single-turn and multi-step code workflows. |
|
|
|
|
|
2. **Code-First Training Focus** |
|
|
Fine-tuned primarily on coding datasets across Python, JavaScript, C++, and Bash, with additional coverage of software documentation, APIs, and debugging tasks. |
|
|
|
|
|
3. **Multi-Step Reasoning in Code** |
|
|
Capable of breaking down complex programming problems, explaining logic, and correcting bugs—ideal for students, engineers, and software instructors. |
|
|
|
|
|
4. **Structured Format Proficiency** |
|
|
Outputs syntactically correct code blocks, JSON, YAML, and Markdown—streamlining integration into tools, notebooks, and docs. |
|
|
|
|
|
5. **Lightweight Yet Powerful** |
|
|
At 4B parameters, it provides strong results without the heavy resource demands of larger models, and is deployable on most modern GPUs or powerful CPUs. |
|
|
|
|
|
6. **Cross-Language Coding Support** |
|
|
Generates and interprets code in 10+ languages with emphasis on real-world application, scripting, and algorithmic problem-solving. |

## **Quickstart with Transformers** |
|
|
|
|
|
```python |
|
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
|
|
|
|
model_name = "prithivMLmods/BetaCeti-Beta-4B-Prime1" |
|
|
|
|
|
model = AutoModelForCausalLM.from_pretrained( |
|
|
model_name, |
|
|
torch_dtype="auto", |
|
|
device_map="auto" |
|
|
) |
|
|
tokenizer = AutoTokenizer.from_pretrained(model_name) |
|
|
|
|
|
prompt = "Write a Python function to check if a number is prime." |
|
|
|
|
|
messages = [ |
|
|
{"role": "system", "content": "You are a helpful coding assistant."}, |
|
|
{"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] |
|
|
print(response) |
|
|
``` |
|
|

## **Intended Use** |
|
|
|
|
|
* Code generation, translation, and refactoring |
|
|
* Teaching and tutoring in programming concepts |
|
|
* Technical documentation generation and API auto-fill |
|
|
* Debugging assistant with error analysis and fixes |
|
|
* Lightweight deployment in IDEs, coding platforms, and offline environments |
|
|

|
|
|
|
## **Limitations** |
|
|
|
|
|
* Smaller context length compared to larger coding models (e.g., >7B) |
|
|
* May require prompt engineering for deeply nested or obscure code patterns |
|
|
* Limited fluency in non-programming natural language dialogue |
|
|
* Not optimized for purely creative writing or storytelling tasks |
|
