Instructions to use kcxain/KernelZero-CUDA-SFT-7B with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use kcxain/KernelZero-CUDA-SFT-7B with Transformers:

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

pipe = pipeline("text-generation", model="kcxain/KernelZero-CUDA-SFT-7B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("kcxain/KernelZero-CUDA-SFT-7B")
model = AutoModelForCausalLM.from_pretrained("kcxain/KernelZero-CUDA-SFT-7B", 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=256)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

+# KernelZero-CUDA-SFT-7B
+KernelZero-CUDA-SFT-7B is the supervised CUDA kernel generation checkpoint used to initialize the CUDA Coder in KernelZero. It is based on Qwen2.5-Coder-7B-Instruct and trained on 42,454 CUDA code-generation examples.
+## KernelBench results
+The paper reports the following results with 10 sampled candidates per problem.
+| Benchmark | pass@1 | pass@5 | pass@10 | fast\_1@1 | fast\_1@10 | fast\_2@1 | fast\_2@10 |
+|---|---:|---:|---:|---:|---:|---:|---:|
+| Level 1 | 70.6 | 94.77 | 98.0 | 15.1 | 29.0 | 6.3 | 14.0 |
+| Level 2 | 59.0 | 90.33 | 94.0 | 2.0 | 9.0 | 1.3 | 6.0 |
+## Intended use
+This checkpoint generates CUDA extensions from PyTorch modules. Use the KernelZero CUDA prompt and validation environment for reproducible evaluation.
+## Loading
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+model_id = "kcxain/KernelZero-CUDA-SFT-7B"
+tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
+model = AutoModelForCausalLM.from_pretrained(
+    model_id,
+    torch_dtype="auto",
+    device_map="auto",
+    trust_remote_code=True,
+)
+```
+## Checkpoint provenance
+This release contains the merged Hugging Face inference weights from SFT checkpoint 3606. Optimizer states, scheduler state, RNG state, and distributed training artifacts are excluded.
