Viper-Coder-v1.1

Viper-Coder-v1.1 is based on the Qwen 2.5 14B modality architecture, designed to be the best for coding and reasoning tasks. It has been fine-tuned on a synthetic dataset leveraging the latest coding logits and CoT datasets, 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 coding tasks, instruction-following, and text generation.

Key Improvements

Best-in-Class Coding Proficiency: Enhanced understanding of programming languages, debugging, and code generation.
Fine-Tuned Instruction Following: Optimized for precise responses, structured outputs (e.g., JSON, YAML), and extended text generation (8K+ tokens).
Advanced Logical & Mathematical Reasoning: Improved multi-step problem-solving and theorem proving.
Long-Context Mastery: Handles up to 128K tokens with an output capability of 8K tokens per response.
Multilingual Code Support: Excels in Python, JavaScript, C++, Java, SQL, and other major programming languages, with documentation in 29+ languages.

Quickstart with Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "prithivMLmods/Viper-Coder-v1.1"

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

prompt = "Write a Python function to merge two sorted lists."
messages = [
    {"role": "system", "content": "You are an advanced AI assistant with expert-level coding and reasoning abilities."},
    {"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

Elite Coding & Debugging: Best-in-class model for writing, analyzing, and optimizing code.
Complex Algorithmic Reasoning: Solves intricate logic problems and algorithm-based challenges.
Scientific & Mathematical Computation: Advanced support for formulas, equations, and theorem verification.
Structured Data Processing: Seamlessly handles JSON, XML, SQL, and data pipeline automation.
Multilingual Programming Support: Proficient in Python, JavaScript, C++, Java, Go, and more.
Extended Technical Content Generation: Ideal for writing documentation, research papers, and technical blogs.

Limitations

High Computational Demand: Requires powerful GPUs/TPUs for smooth inference due to 14B parameters.
Language-Specific Variability: Performance may vary across different programming languages.
Possible Error Propagation: Extended text outputs might introduce logical inconsistencies.
Limited Real-World Awareness: The model does not have access to real-time internet updates.
Prompt Sensitivity: Performance depends on how well the prompt is structured.
