tft-benchmark-s4-tft-Qwen3-1.7B
A
Qwen3-1.7B model fine-tuned for multi-turn tool calling as part of the
TFT (Training from Traces) Benchmark.
- Pipeline: TFT Pipeline
- Scenario: S4 Low Data — Low Data
- LLM-as-a-judge score: 0.852
- staged_tool_call score: 0.74
Benchmark Overview
This model is one of 10 models trained for the TFT benchmark, which compares two approaches to training Small Language Models (SLMs) from production traces:
- TFT Pipeline: trace filtering + committee relabeling + synthetic data generation + finetuning
- Direct Training: train directly on raw/corrupted traces (no filtering, no relabeling, no synth gen)
Both pipelines are evaluated on the same held-out test set of 34 multi-turn Restaurants_1 conversations (~359 per-turn evaluation pairs) using LLM-as-a-judge scoring (0-1 scale).
Scenario: S4 Low Data — Low Data
Only 5 clean Restaurants_1 traces (subsampled from 327). Tests extreme data scarcity — Direct Training has only ~55 per-turn examples after expansion, while TFT amplifies from 5 seed conversations via synthetic data generation.
Training Details
Trained using the TFT (Training from Traces) pipeline: production traces are filtered, committee-relabeled by multiple LLMs, then used as seeds for synthetic data generation. The student model is fine-tuned on the resulting synthetic dataset.
Configuration
- Base model: Qwen3-1.7B
- Task: multi-turn-tool-calling-closed-book
- Teacher / synth gen model: zai.glm-5
- Judge model: openai.gpt-oss-120b
- Committee (TFT relabeling): openai.gpt-oss-120b + zai.glm-5
- Training: LoRA fine-tuning, merged weights
Target Tools
Based on the
Schema-Guided Dialogue (SGD) dataset — restaurant search and reservation:
respond_to_user — send text messages to the userFindRestaurants — search restaurants by cuisine, city, price range, live music, alcoholReserveRestaurant — reserve a table (restaurant name, city, time, date, party size)
