XL-LuaCopilot-0.6B-FFT

XL-LuaCopilot-0.6B-FFT is a large language model (LLM) based on the Qwen architecture(Qwen3-0.6B-Base), specifically designed for code generation tasks in Lua programming language. It has been full fine-tuned (FFT) to improve its performance and efficiency when generating Lua code.

I sugggest you use "chat_template_kwargs": {"enable_thinking": false} because my train data with none thinking. I also found low temperature ususually works well for code generation tasks.

How To Use

With OpenAI Compatible API (llama.cpp:llama-server)

-> RESPONSE ->

{

            "finish_reason": "stop",
            "index": 0,
            "message": {

                "content": "<think>\n\n</think>\n\nt = \"你好世界\"\n  print(text)\ne"
            }
        }
    ],
    ...
}

I know Qwen has <|fim_prefix|> / <|fim_suffix|> / <|fim_middle|> tokens, but I'm not sure Qwen3 trains these tokens (I just know Qwen2.5-Coder does). To use code generation easily, I use chatml format.

If you just want to chat with it, you can use some tricks like this:

<|im_end|>
<|im_start|>system
prefix<|im_end|>
<|im_start|>user
do
    --打印：你好世界
    local tex<|im_end|>
<|im_start|>system
suffix<|im_end|>
<|im_start|>user
nd<|im_end|>
<|im_start|>system
middle

It dosen't work very well, but it's a good way let you fast try. It will convert to this prompt text:

<|im_start|>user
<|im_end|>
<|im_start|>system
prefix<|im_end|>
<|im_start|>user
do
    --打印：你好世界
    local tex<|im_end|>
<|im_start|>system
suffix<|im_end|>
<|im_start|>user
nd<|im_end|>
<|im_start|>system
middle<|im_end|>

Hope model skip first <|im_start|>user\n<|im_end|> part.
