Libraries

How to use CohereLabs/c4ai-command-r-plus-08-2024 with Transformers:

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

pipe = pipeline("text-generation", model="CohereLabs/c4ai-command-r-plus-08-2024")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("CohereLabs/c4ai-command-r-plus-08-2024")
model = AutoModelForCausalLM.from_pretrained("CohereLabs/c4ai-command-r-plus-08-2024")
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]:]))

Is this just something sent to the official Cohere API, or is it something we can control using the Transformers version in this repo via the preemble in the system message?

I think they still use the same safety preamble. Those settings just recall one.

@jukofyork Actually, you can use the safety instructions present in https://docs.cohere.com/docs/safety-modes to recreate the same behavior you get in the API! Sorry for the confuision.
