Ult1-Coding

A 3-billion-parameter coding specialist -- master-level software engineer.

Based on Qwen2.5-3B-Instruct with an embedded master programmer system prompt containing few-shot coding demonstrations and a coding-focused LoRA adapter (rank 16, 8 target module types).

Usage:

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("teolm30/Ult1-coding")
tokenizer = AutoTokenizer.from_pretrained("teolm30/Ult1-coding")

messages = [{"role": "user", "content": "Write a Python async web scraper with retry logic"}]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=512)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

The system prompt with few-shot examples is auto-injected by the chat template - no manual system prompt needed.
