tft-benchmark-s3-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: S3 Schema Drift — Schema Drift
• LLM-as-a-judge score: 0.844
• staged_tool_call score: 0.748

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: S3 Schema Drift — Schema Drift

50/50 mix of Restaurants_2 (146 traces) and Restaurants_1 (146 traces) with all function and parameter names randomly renamed. 0% of training data uses correct R1 function names — 21 unique function names and 47 unique parameter names across the training set.

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 user
• FindRestaurants — search restaurants by cuisine, city, price range, live music, alcohol
• ReserveRestaurant — reserve a table (restaurant name, city, time, date, party size)

Full Benchmark Results

Scenario	TFT	Direct	Delta
S1 Baseline	0.866	0.864	+0.2pp
S2 Noisy Labels	0.844	0.721	+12.3pp
S3 Schema Drift	0.844	0.585	+25.9pp
S4 Low Data	0.852	0.649	+20.3pp
S5 Trace Mixing	0.858	0.694	+16.4pp

TFT matches Direct Training on clean data (S1) and outperforms it on every corrupted scenario by 12-26 percentage points.
