from transformers import pipeline

generator = pipeline(model="ptrdvn/kakugo-3B-kin", task="text-generation")

user_input = input("Please enter your input to the model in Kinyarwanda:")

do_reasoning = False

open_thinking_tag = "<think>"
close_thinking_tag = "</think>"

if do_reasoning:
    sys_msg = f"Before you respond, first think about your response and enclose your thinking process in {open_thinking_tag} and {close_thinking_tag} delimiters."
else:
    sys_msg = "Be concise in your responses."

message = [
        {"role": "system", "content": sys_msg},
        {"role": "user", "content": user_input}
    ]

output = generator(
    message,
    do_sample=False,
    repetition_penalty=1.05,
)

model_response = output[0]["generated_text"][-1]["content"]

if do_reasoning:
    model_response = model_response.split(close_thinking_tag)[-1]

print(model_response)

N.B. - We recommend using a repetition_penalty of 1.05 as sometimes the model can stuck in a loop of generating repetitive text when generating low-resource languages.

You can set do_reasoning to be either True or False to turn "thinking mode" on or off, respectively. If the model is used in thinking mode, then it will take longer to generate a response, but may lead to a better generated response. This mode is still experimental, so try both using and not using it for your use-case.

vLLM (Recommended for performance)

First, make sure vllm is installed on your machine.

pip install vllm

Then run the following Python code to generate a response from the LLM.

python

from vllm import LLM, SamplingParams
llm = LLM(model="ptrdvn/kakugo-3B-kin")

user_input = input("Please enter your input to the model in Kinyarwanda:")

do_reasoning = True

open_thinking_tag = "<think>"
close_thinking_tag = "</think>"

if do_reasoning:
    sys_msg = f"Before you respond, first think about your response and enclose your thinking process in {open_thinking_tag} and {close_thinking_tag} delimiters."
else:
    sys_msg = "Be concise in your responses."

sampling_params = SamplingParams(temperature=0, repetition_penalty=1.05, max_tokens=2048)

messages = [[
        {"role": "system", "content": sys_msg},
        {"role": "user", "content": user_input}
    ]]

output = llm.chat(messages, sampling_params)

model_response = output[0].outputs[0].text

if do_reasoning:
    model_response = model_response.split(close_thinking_tag)[-1]

print(model_response)

N.B. - When using vllm for inference of multiple inputs, we recommend inputting them all at once. I.e., add more items to the outer list of the messages variable in the above script. More on vLLM optimization.

We recommend using a repetition_penalty of 1.05 as sometimes the model can stuck in a loop of generating repetitive text when generating low-resource languages.

Training data

The training data for this model can be found at ptrdvn/kakugo-kin.

This data was created by prompting openai/gpt-oss-120b to generate prompts and responses in Kinyarwanda. We also translate a set of prompts and responses from the BAAI/Infinity-Instruct dataset.

More details about exactly how we created our data can be found in our paper.

Training

Full details of how this model was created (and how you can train a model in your own chosen language) can be found on our Github repo.

To make this model, we fine-tuned ibm-granite/granite-4.0-micro for 1 epoch on ptrdvn/kakugo-kin using Llama Factory.
