Questions
PII Tracer FAQs
What is PII Tracer?+
PII-Tracer is Perplexity's compact 0.6B bidirectional Qwen3 encoder for detecting and redacting personally identifiable information in multilingual conversations. It is developed by Perplexity and its current sourced lifecycle status is active.
What inputs and outputs does PII Tracer support?+
PII Tracer's current record lists Text as input and Text as output.
How much context does PII Tracer support?+
The current record lists a 4K-token context window and does not report a maximum output length.
Is PII Tracer available through an API?+
PII Tracer is explicitly marked as not API-available in the current record.
How large is PII Tracer?+
The current record lists 596.1M total parameters and an unknown active parameter count. Its architecture is PiiMaskingModel with bidirectional Qwen3 encoder.
What capabilities and tasks does PII Tracer support?+
PII Tracer's recorded capabilities are classification, pii-detection, redaction, sensitivity-classification, and token-classification. Its supported tasks are pii-detection, text, and token-classification.
How much does PII Tracer cost through an API?+
PII Tracer has no verified hosted API offering, so no provider token price applies. It is a downloadable or self-hosted artifact whose cost depends on the serving infrastructure and workload.
Can PII Tracer be self-hosted?+
PII Tracer is an open-weight model. Self-hosting is supported, and the recorded license is mit.
Does PII Tracer have related versions or aliases?+
No predecessor is recorded. No successor is recorded. Recorded aliases are perplexity-ai/pplx-pii-masking, PII-Tracer, and pplx-pii-masking.
Which models can PII Tracer be compared with?+
The current compatible peer set includes Bolmo 7B, MolmoWeb 4B, MolmoWeb 8B, Olmo 3 7B Think, and ERNIE 4.5 0.3B PT. Compatibility requires shared sourced modalities and tasks; it does not imply that one model is better. Browse model comparisons →
