Model Card for Model ID

This LoRA is an educationl project from the Hugging Face Agents Course Bonus Unit that fine-tunes Google's Gemma 2 2b IT model to use a thinking step followed by tool-use.

Model Details

Model Description

This model is based on Google's Gemma 2 2b IT model, which has already been fine-tuned on for instruction following. It uses a modified subset of the NousResearch/hermes-function-calling-v1 dataset: Jofthomas/hermes-function-calling-thinking-V1, which adds a thinking step to the base dataset.

I trained it locally on my NVIDIA GeForce RTX 3060 GPU, so reduced the LoRA rank from 16 to 8.

Disclaimer: This model is for education only: the course states there is not enough data in the training set to be reliable, the model is very small and meant for things like on-device classification tasks, and I reduced the LoRA rank.

<think>Okay, so the user is asking to convert 500 USD to Euros. I need to figure out how to respond using the available functions. Let me look at the tools provided. There's a function called convert_currency which does exactly that—it converts one currency to another. The parameters required are amount, from_currency, and to_currency. The user provided all these details: 500 USD to EUR. 

I should make sure I'm using the correct function and parameters. The amount is 500, from_currency is USD, and to_currency is EUR. I don't need to make any assumptions here because the user provided all the necessary information. 

So, the next step is to call the convert_currency function with these arguments. That should give the user the converted amount they need.
</think><tool_call>
{'name': 'convert_currency', 'arguments': {'amount': 500, 'from_currency': 'USD', 'to_currency': 'EUR'}}
</tool_call><end_of_turn><eos>

✅ Which successfully calls the tool and is very close to the target.
