Instructions to use Qwen/Qwen3-30B-A3B-Instruct-2507 with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use Qwen/Qwen3-30B-A3B-Instruct-2507 with Transformers:

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

pipe = pipeline("text-generation", model="Qwen/Qwen3-30B-A3B-Instruct-2507")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen3-30B-A3B-Instruct-2507")
model = AutoModelForCausalLM.from_pretrained("Qwen/Qwen3-30B-A3B-Instruct-2507", 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]:]))

RTX 5090 + Qwen 30B MoE @ 135 tok/s in NVFP4 - Full guide with C++ patches
Tutorial | Guide
Spent 4 days getting NVFP4 working on consumer Blackwell. T RT-LLM 1.2.0rc4 has critical bugs that prevent loading managed weights for FP4 models - the allocator uses 2x VRAM and type checking rejects packed INT8 weights.

Results on RTX 5090 (32GB):

Why so fast? Qwen 3 30B is MoE - only ~2.4B params active per token. Combined with Blackwell's native FP4 tensor cores = 7B-level speed with 30B knowledge.

What's in the guide: - SWAP trick for quantization (64GB RAM + 64GB SWAP = enough) - --fast_build flags to avoid compiler OOM - C++ runtime patch to fix allocator bug and type mismatch - Open WebUI integration fix Full tutorial + patches: https://github.com/JohnTDI-cpu/trtllm-nvfp4-blackwell-fix

This was mass amount of pain so hoping to save others the trouble.
