Breeze Guard 26: Taiwanese Mandarin Safety Classifier

Breeze Guard 26, developed by MediaTek Research, is an 8 billion parameter safety classifier built upon the Breeze 2 8B Instruct model. It is specifically fine-tuned with 12,000 human-verified samples to detect harmful content in user prompts, focusing on Taiwan-specific safety risks. While primarily optimized for Taiwanese Mandarin, it also offers reasonable English support.

Key Capabilities

• Prompt-level Harmfulness Detection: Identifies unsafe content directly in user inputs.
• Taiwan-Specific Risk Categories: Trained to detect six categories relevant to Taiwan: scam, fin_malpractice (illegal finance), health_misinfo (health misinformation), gender_bias, group_hate (ethnic/religious/regional hate speech), and pol_manipulation (political disinformation).
• Dual Inference Modes: Supports a 'thinking mode' (judge{think}) for explainable Chain-of-Thought reasoning, and a 'non-thinking mode' (judge{no_think}) for low-latency, direct safety verdicts.
• Performance: Achieves strong results on the TS-Bench (Taiwan Safety Benchmark), with an overall score of 0.86 in non-thinking mode, outperforming Granite Guardian 3.3.

Use Cases

• Content Moderation: Ideal for filtering user-generated content in applications targeting Taiwanese users.
• Fraud Detection: Particularly effective at identifying scam attempts and financial malpractice in Mandarin text.
• Explainable AI: The 'thinking mode' is valuable for scenarios requiring transparency in safety classifications.
• High-Throughput Applications: The 'non-thinking mode' is suitable for real-time or batch processing where speed is critical.

Limitations

• May exhibit over-sensitivity, potentially flagging legitimate content.
• Performance is lower for English content compared to Taiwanese Mandarin.
• Limited to prompt-level detection; does not evaluate model responses.
• Only covers six predefined risk categories, potentially missing novel harm types.
