Instructions to use RadixArk/Kimi-K3-DSpark with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use RadixArk/Kimi-K3-DSpark with Transformers:

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

pipe = pipeline("text-generation", model="RadixArk/Kimi-K3-DSpark", trust_remote_code=True)

# Load model directly
from transformers import AutoTokenizer, AutoModel

tokenizer = AutoTokenizer.from_pretrained("RadixArk/Kimi-K3-DSpark", trust_remote_code=True)
model = AutoModel.from_pretrained("RadixArk/Kimi-K3-DSpark", trust_remote_code=True, device_map="auto")
