🎛️ Training signal Verified online data synthesis + multi-turn Progress Reward
✅ Release status Final ToolWeave Stage 3 model

ToolWeave Stage 3 expands multi-turn tool-use learning through capability-boundary detection, verified online data synthesis, strict execution and semantic validation, dynamic replay, and combined global/local tool-call credit.

📊 Stage 3 evaluation

The final ToolWeave Stage 3 checkpoint was evaluated on the canonical balanced 400-row held-in set: 100 entries each from Base, Missing Function, Missing Parameter, and Long Context. These values are complete-entry BFCL Multi-Turn accuracies, not the training-time Progress Reward (R_P).

Model Overall Base Missing Function Missing Parameter Long Context Correct entries
ToolWeave Stage 3 48.50 56.00 50.00 42.00 46.00 194 / 400

Because the four categories are balanced, the overall score is their unweighted mean and the complete-entry accuracy over all 400 entries:

(56.00 + 50.00 + 42.00 + 46.00) / 4 = 48.50

🚀 Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "muradil211/ToolWeave_stage3"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, device_map="auto")

Tool-use inference requires the model's function schemas and the Qwen3-compatible tool-call format.
