Model Card for Llama-3.2-1B-Instruct-v2-FC

This model is a fine-tuned version of meta-llama/Llama-3.2-1B-Instruct on the argilla-warehouse/apigen-smollm-trl-FC dataset. It has been trained using TRL.

Based on the question, you will need to make one or more function/tool calls to achieve the purpose.

If the given question lacks the parameters required by the function, also point it out.

You have access to the following tools:

The example format is as follows. Please make sure the parameter type is correct. If no function call is needed, please make the tool calls an empty list '[]'.
