Instructions to use unsloth/functiongemma-270m-it with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use unsloth/functiongemma-270m-it with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="unsloth/functiongemma-270m-it")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("unsloth/functiongemma-270m-it")
model = AutoModelForCausalLM.from_pretrained("unsloth/functiongemma-270m-it")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

"""
vLLM has started using the Transformers v5 style rope_parameters and patches it into configs loaded with Transformers v4.

vLLM 0.12.0 uses the existence of rope_parameters to decide whether or not to set a default value for it, i.e.:

    if rope_theta is not None:
        if not hasattr(config, "rope_parameters"):
            config.rope_parameters = {"rope_type": "default"}
        config.rope_parameters["rope_theta"] = rope_theta

This causes an error with this model because rope_parameters will remain None and the following dict assignment will fail.

https://github.com/vllm-project/vllm/pull/30983 fixes this on the vLLM side for (hopefully) v0.13.0 onwards.

Removing these fields from the checkpoint should fix this model for vLLM v0.12.0 in the meantime.
