Libraries

How to use spade-rl/SPADE-Qwen3-4B-ToolUse with Transformers:

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

pipe = pipeline("text-generation", model="spade-rl/SPADE-Qwen3-4B-ToolUse")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("spade-rl/SPADE-Qwen3-4B-ToolUse")
model = AutoModelForCausalLM.from_pretrained("spade-rl/SPADE-Qwen3-4B-ToolUse", 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]:]))

SPADE-Qwen3-4B-ToolUse

SPADE checkpoint for the tool use setting, trained from Qwen/Qwen3-4B-Instruct-2507.

SPADE trains a single model in two roles: as a proposer that writes executable environments, and as an actor that plays them. The proposer is rewarded for producing environments at the frontier of what the actor can currently solve, so the curriculum keeps pace with the policy instead of being fixed in advance.


Base model	`Qwen/Qwen3-4B-Instruct-2507`
Setting	`tool_use`
Released checkpoint	`iter399`
Grounding corpus	`spare-rl/spade-grounding-corpus-tooluse-15k`

Environments. Multi-turn tool-use environments generated online, grounded on the 15k tool-use corpus.

Checkpoint selection. Checkpoint at step 399 of the run.

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "spare-rl/SPADE-Qwen3-4B-ToolUse"
tok = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, device_map="auto")
