qwen2.5-7b-instruct-sft-v5

This repository provides a merged full model produced by supervised fine-tuning for AgentBench-oriented ALFWorld/DBBench robustness.

Training Objective

Improve strict action selection reliability for ALFWorld prompts and strengthen SQL error-recovery robustness for DBBench prompts, while keeping balanced mixed-task behavior.

Training Configuration

• LoRA target modules: q_proj,k_proj,v_proj,o_proj,gate_proj,up_proj,down_proj
• Output learn mode: from_marker (ACTION: and Action: markers)
• Max sequence length: 4096
• Max steps: 400
• Epochs: 1
• Learning rate: 2.0e-6
• Per-device train batch size: 1
• Per-device eval batch size: 2
• Gradient accumulation steps: 32
• Effective global batch size: 32
• Warmup ratio: 0.03
• Weight decay: 0.01
• Eval/Save steps: 50 / 25

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "uchkw/qwen2.5-7b-instruct-sft-v5"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, device_map="auto")

  • u-10bei/dbbench_sft_dataset_react_v4
  • u-10bei/dbbench_sft_dataset_react_v3
• Data construction policy (concise):
  • ALFWorld samples were converted into strict one-line action supervision (ACTION: ...) with exact matching against AVAILABLE ACTIONS.
  • Added hard-copy style ALF augmentation to reinforce exact action copying and reduce formatting drift.
  • Mixed DBBench supervision and recovery-oriented examples for Unknown column style failures.
  • Mixed train ratio was controlled at approximately ALF:DB = 55:45.
