Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "kiranpg/Qwen2.5-OCamler-1.5B-Instruct-v2"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype="auto", device_map="auto")

messages = [
    {"role": "user", "content": "Write an OCaml function to compute the factorial of a number."}
]

text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)

outputs = model.generate(**inputs, max_new_tokens=512, temperature=0.7, do_sample=True)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Intended Use

This model is designed for generating OCaml code solutions given natural language problem descriptions. It has been fine-tuned on OCaml programming problems to improve its ability to produce correct, idiomatic OCaml code.

Limitations

• —The model may not always produce syntactically correct OCaml code
• —Complex algorithmic problems may require multiple attempts
• —The model works best with clear, well-specified problem descriptions

Training Infrastructure

Trained using TRL's GRPOTrainer with LoRA adapters.
