Libraries

How to use CohereLabs/c4ai-command-a-03-2025 with Transformers:

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

pipe = pipeline("text-generation", model="CohereLabs/c4ai-command-a-03-2025")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("CohereLabs/c4ai-command-a-03-2025")
model = AutoModelForCausalLM.from_pretrained("CohereLabs/c4ai-command-a-03-2025")
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]:]))

Please add this model to huggingchat, this model is highly considered one of the best because it does not have any censorship............

Here is the source code for huggingchat: https://github.com/huggingface/chat-ui

Hey @gmanskibidi , you can use Command A in our Hugging Face space (that uses chat-ui!) -- https://huggingface.co/spaces/CohereLabs/c4ai-command

Hey @gmanskibidi , you can use Command A in our Hugging Face space (that uses chat-ui!) -- https://huggingface.co/spaces/CohereLabs/c4ai-command

Nah, since this space requires zerogpu which requrires a subscription, its best to add this model to huggingchat anyway alongside the existing command r+.

@gmanskibidi our space does not require a subscription to be used.

@gmanskibidi our space does not require a subscription to be used.

but wouldn't it be better for you to add this model to huggingchat instead of requiring us to run it in your own private space? we might need to use other models alongside command a inside huggingchat as well.

Closing as huggingchat is no longer available.
