Introducing HushPolicy DSL v1
Fine-tune moderation behavior without retraining models. The HushPolicy YAML DSL lets you raise thresholds for specific contexts, retrieve semantically similar examples for edge-case calibration, and inject custom prompts into the Tier 3 LLM judge.
How we moved the metering pipeline from goroutines to SQS
Every moderation request needs to be logged, usage metered, and potentially replayed. In this post, we walk through why in-process goroutines weren't enough, and how we built a durable, idempotent SQS consumer with graceful drain on shutdown.
Counterfactual explanations: why we explain the counterfactual, not just the decision
Most moderation APIs tell you what was blocked. HushSafe tells you why, and more importantly — what would need to change for the decision to flip. Here's the design behind our counterfactual explanation endpoint.
We replaced Detoxify with a direct ONNX export of unitary/multilingual-toxic-xlm-roberta to get real per-language scores, eliminate fabricated constants, and cut inference latency by 40% through INT8 quantization.
