Libraries

How to use dongguanting/ToolSpace-8B with Transformers:

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

pipe = pipeline("text-generation", model="dongguanting/ToolSpace-8B")
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("dongguanting/ToolSpace-8B")
model = AutoModelForCausalLM.from_pretrained("dongguanting/ToolSpace-8B", 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]:]))

ToolSpace-8B

Code · Evaluation · 8B · 35B-A3B · 744B-A40B

ToolSpace-8B is a Qwen3-8B agent model trained with ToolSpace trajectories and on-policy agent reinforcement learning for long-horizon tool use.

ToolSpace constructs a tool-composition graph from real execution traces, capturing data, state, and retry dependencies. It synthesizes cross-environment tasks through state-aware walks with rollback and keeps trajectories that pass execution-based verification.

Paper: ToolSpace: Scaling Tool-Centric Environment Synthesis for Long-Horizon Agents.
