Overview

Kopro 4.0 Pro is the larger model in the Kopro 4.0 family. It is a LoRA fine-tune of Qwen3-Coder-30B-A3B-Instruct that keeps the base model's coding and tool-use strength and adds the Kopro voice: short, confident, to the point, in English or Russian.

Quick start

Ollama

ollama run hf.co/Kvikontent/kopro-4.0-pro-GGUF:Q4_K_M

llama.cpp

llama-server -hf Kvikontent/kopro-4.0-pro-GGUF:Q4_K_M --jinja -c 8192

Recommended system prompt

The creator identity is not reliably learned from training data alone, so set it explicitly:

ะขั‹ Kopro 4.0 Pro, ั‚ะตะฑั ัะพะทะดะฐะป ะ’ะฐัะธะปะธะน ะšะฐั†ั‹ะบะฐ.

Agent / tool calling

The chat template embedded in the GGUF supports the standard OpenAI-style tools field. The model was tuned on trajectories with these tools: read_file, edit_file, write_file, grep, bash.

Files

File Size Use
kopro-4.0-pro-Q4_K_M.gguf 18.6 GB Ready to run in Ollama / llama.cpp / LM Studio
lora/ 2.5 GB PEFT LoRA adapter, for further training or other quantizations

Load the adapter on the original base model:

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

base = AutoModelForCausalLM.from_pretrained("Qwen/Qwen3-Coder-30B-A3B-Instruct", torch_dtype="auto", device_map="auto")
model = PeftModel.from_pretrained(base, "Kvikontent/kopro-4.0-pro-GGUF", subfolder="lora")
tok = AutoTokenizer.from_pretrained("Kvikontent/kopro-4.0-pro-GGUF", subfolder="lora")

Limitations

  • Agent quality comes from the base model. The 30 agent trajectories mainly teach the tool format; for long multi-step work in big repositories, expect base Qwen3-Coder level, not frontier level.
  • Persona. The model is tuned to be blunt and opinionated, and may speak dismissively about other AI products. Steer it with the system prompt if that does not fit your product.
  • Identity. Without a system prompt it may invent a creator name.
  • Q4 quantization loses a little quality compared to the full-precision weights.
