Instructions to use meta-llama/Meta-Llama-3-8B-Instruct with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use meta-llama/Meta-Llama-3-8B-Instruct with Transformers:

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

pipe = pipeline("text-generation", model="meta-llama/Meta-Llama-3-8B-Instruct")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("meta-llama/Meta-Llama-3-8B-Instruct")
model = AutoModelForCausalLM.from_pretrained("meta-llama/Meta-Llama-3-8B-Instruct", device_map="auto")
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]:]))

Uncaught (in promise) SyntaxError: Unexpected token 'E', "Expected r"... is not valid JSON

im using javascript api inference and this returns an error in the console>>

"Uncaught (in promise) SyntaxError: Unexpected token 'E', "Expected r"... is not valid JSON"

the problem seems to be with

query({"inputs": "Hi? "}).then((response) => {
console.log(JSON.stringify(response));
});

when i use the default it works and returns a response in the console:

query({"inputs": "Can you please let us know more details about your "}).then((response) => {
console.log(JSON.stringify(response));
});

here is the full code, replaced my key with the default:

async function query(data) {
const response = await fetch(
"https://api-inference.huggingface.co/models/meta-llama/Meta-Llama-3-8B-Instruct",
{
headers: { Authorization: "Bearer xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" },
method: "POST",
body: JSON.stringify(data),
}
);
const result = await response.json();
return result;
}

query({"inputs": "Hi? "}).then((response) => {
console.log(JSON.stringify(response));
});
