  • removing verbose reasoning blocks
  • truncating oversized responses
  • formatting into chat-style conversations

This improved:

  • training stability
  • VRAM efficiency
  • response quality
  • inference speed

Features

  • Lightweight local inference
  • Structured software engineering responses
  • Architecture-oriented outputs
  • Coding copilot style formatting
  • QLoRA optimized deployment

Example Usage

from transformers import AutoTokenizer, AutoModelForCausalLM

model_name = "Flare0p/Qwen3-Agentic-Coder-0.6B"

tokenizer = AutoTokenizer.from_pretrained(model_name)

model = AutoModelForCausalLM.from_pretrained(model_name)

prompt = "Design a scalable authentication system for microservices."

inputs = tokenizer(prompt, return_tensors="pt")

outputs = model.generate(
    **inputs,
    max_new_tokens=200
)

print(tokenizer.decode(outputs[0]))

Intended Use

This model is intended for:

  • educational AI engineering projects
