Spec Coder V1
Spec Coder is a cutting-edge, open-source AI model designed to assist with fundamental coding tasks. It is built on the Llama architecture, allowing seamless access via tools like llama.cpp and Ollama. This makes Spec Coder highly compatible with a variety of systems, enabling flexible deployment both locally and in the cloud.
Trained on vast datasets, Spec Coder excels in generating code, completing code snippets, and understanding programming tasks across multiple languages. It can be used for code completion, debugging, and automated code generation, acting as a versatile assistant for developers.
Spec Coder is optimized for integration into developer tools, providing intelligent coding assistance and facilitating research in programming languages. Its advanced transformer-based architecture, with 4 billion parameters, allows it to perform tasks across different environments efficiently.
The model supports various downstream tasks including supervised fine-tuning (SFT) and reinforcement learning (RL) to improve its performance for specific programming tasks.

Sample Usage
Here are examples of how to run and interact with Spec Coder:
from transformers import AutoModelForCausalLM, AutoTokenizer
model_name = "SVECTOR-CORPORATION/Spec-Coder-4b-V1"
model = AutoModelForCausalLM.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)
input_code = "def factorial(n):\n if n == 0:"
inputs = tokenizer(input_code, return_tensors="pt")
outputs = model.generate(inputs['input_ids'], max_length=50, num_return_sequences=1)
generated_code = tokenizer.decode(outputs[0], skip_special_tokens=True)
print("Generated Python code:\n", generated_code)
