Overview

Kopro 4.0 Flash is the fast model in the Kopro 4.0 family. It is a LoRA fine-tune of Qwen3-14B for everyday conversation, with the Kopro voice: short, confident, a little sharp, in English or Russian.

Good at Notes
๐Ÿ’ฌ Everyday chat Advice, opinions, casual talk, multi-turn conversations
๐Ÿ”ฌ Explanations Science, tech, culture, written so they are easy to follow
๐Ÿณ Practical help Cooking, how-tos, life questions
๐Ÿ’ป Simple code Snippets and small functions

Quick start

Ollama

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

Turn thinking off in API calls ("think": false). The model was trained with thinking disabled.

llama.cpp

llama-server -hf Kvikontent/kopro-4.0-flash-GGUF:Q4_K_M --jinja -c 8192 \
  --chat-template-kwargs '{"enable_thinking": false}'

Recommended system prompt

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

Load the adapter on the original base model:

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

base = AutoModelForCausalLM.from_pretrained("Qwen/Qwen3-14B", torch_dtype="auto", device_map="auto")
model = PeftModel.from_pretrained(base, "Kvikontent/kopro-4.0-flash-GGUF", subfolder="lora")

Limitations

  • No thinking mode. Hard math and multi-step logic are weaker than Qwen3-14B with thinking enabled.
  • Knowledge comes from the base model. Fine-tuning changes style and identity, not facts. Double-check specific numbers and claims.
  • 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.
