Vela Safety
Vela Safety detects general content risk to help route requests to appropriate safety handling.
307M parameters · Input capacity: 32,768 tokens, including special tokens.
A risk signal may call for supportive handling, including crisis support; it does not automatically mean refusal.
Evaluation
Macro F1 (×100), compared with the original mmBERT Safety model on identical development inputs. Higher is better.
Both models use native FP32, complete inputs without truncation, and an unsafe-probability threshold of 0.5. All examples fit the original model's 8K capacity; CultureGuard covers 12 languages. AEGIS and CultureGuard retain their source labels. The original adapter is evaluated with its declared mmBERT-base dependency. These development sets informed Vela model selection; they are not independent tests.
