Mille-Pensees

Mille-Pensées

Model Summary

Mille-Pensées is a french math reaoning model finetuned on the Mille-Pensées-Dataset from the Qwen2.5-7B-Instruct model. It performs similarly or better than Qwen2.5-Math-7B-Instruct on most French Math Benchmarks while reasoning in french instead of english. It also offers superior performances on English Math and General Benchmarks.

Evaluation was done with vllm and math-verify for Math benchmarks (temperature=0.6, top_p=0.95, top_k=20, min_p=0, presence_penalty=0.5, max_tokens=38192) and lm-evaluation-harness for the general English Benchmarks.

Usage

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

model_path = "GLauzza/Mille-Pensees"

# Load tokenizer and model
tokenizer = AutoTokenizer.from_pretrained(model_path)
model = AutoModelForCausalLM.from_pretrained(
    model_path, torch_dtype=torch.float16, device_map="auto"
)

# Example input
messages = [{"role": "user", "content": "Combien vaut 1+1?"}]
input_ids = tokenizer.apply_chat_template(messages, tokenize=True, add_generation_prompt=True, return_tensors='pt').to("cuda")

generated_ids = model.generate(input_ids, max_new_tokens=38192, temperature=0.6, repetition_penalty=0.5, do_sample=True, eos_token_id=tokenizer.eos_token_id)
response = tokenizer.decode(generated_ids[0], skip_special_tokens=True, clean_up_tokenization_space=True)
print(f"Réponse: {response}")
