Training Details

Training Data

The model was trained using the ThinkSafe self-generated safety alignment methodology. See the paper for details on the training data generation process.

Training Procedure

This model uses LoRA (Low-Rank Adaptation) for efficient fine-tuning on top of the Qwen3-0.6B base model. The training follows the ThinkSafe framework for safety alignment in reasoning models.

Training Hyperparameters

Training regime: Mixed precision training with PEFT/LoRA

Evaluation

Please refer to the ThinkSafe paper for detailed evaluation results and methodology.

Testing Data, Factors & Metrics

Testing Data

See the paper for details on evaluation datasets and benchmarks used.

Metrics

The model was evaluated on safety benchmarks and reasoning tasks. Refer to the paper for specific metrics and results.

Environmental Impact

Carbon emissions can be estimated using the Machine Learning Impact calculator presented in Lacoste et al. (2019).
