T-Bench Qwen SFT Multi-Task NAT v11

Model Description

This is a Qwen3-8B model fine-tuned on terminal bench tasks using Negative-Aware Training (NAT) v11. This model represents the latest iteration in the NAT series with enhanced negative example strategies.

Training Details

• Base Model: Qwen/Qwen3-8B
• Training Method: Negative-Aware Training (NAT) v11
• Epochs: 300
• Learning Rate: 5e-5
• Max Length: 32768 tokens
• Batch Size: 4 (2 per GPU with data parallelism)
• Attention: FlashAttention 2
• Precision: bfloat16

Dataset Composition

The training dataset includes a balanced mix of positive and negative examples:

• Positive Examples: Successful terminal command executions
• Negative Examples: Various failure patterns and common mistakes
• Context Length: Extended to 32768 tokens for longer terminal sessions

NAT v11 Improvements

This version builds upon previous NAT iterations with:

• Enhanced negative example generation
• Better coverage of edge cases
• Improved system prompts
• More diverse failure patterns

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(
    "Aznaur/tbench-qwen-sft-multitask-nat-v11",
    trust_remote_code=True,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(
    "Aznaur/tbench-qwen-sft-multitask-nat-v11",
    trust_remote_code=True
)

Model Features

• Context Length: 32768 tokens
