Introduction of gliner-stream-pii-v1.0
Model Details of gliner-stream-pii-v1.0
GLiNER Streaming PII — Qwen3 0.6B
An open-label PII detector built with the GLiNER streaming-span architecture and a Qwen3-0.6B causal backbone. It supports regular full-text inference, cached incremental streams, and full-session recomputation. This model was developed in collaboration between Wordcab and Knowledgator . For enterprise-ready, specialized PII/PHI/PCI models, contact us at [email protected] .
Architecture
Following the component schema in the GLiNER architecture docs , this checkpoint is composed of:
Install and load
pip install "gliner>=0.2.28"
import torch
from gliner import GLiNER
device = "cuda" if torch.cuda.is_available() else "cpu"
dtype = "bf16" if device == "cuda" else "fp32"
model = GLiNER.from_pretrained(
"knowledgator/gliner-stream-pii-v1.0",
load_tokenizer=True,
map_location=device,
dtype=dtype,
).eval()
labels = [
"person",
"email address",
"phone number",
"street address",
"credit card number",
"passport number",
]
Three inference strategies
| Strategy | API | What is computed | Best for |
|---|---|---|---|
| 1. Stateless full text |
No
session_id
|
Complete input and label prompt | Documents, batches, independent requests |
| 2. Cached incremental |
session_id=[id]
|
New chunk only; decoder KV, labels, words, and span history are reused | Live chat, ASR, logs, token streams |
| 3. Full recompute |
session_id=[id], recompute=True
|
Accumulated session plus new chunk; cache and all spans are rebuilt | Final pass, changed labels, correction after drift |
1. Stateless full text
entities = model.predict_entities(
"Jane Doe can be reached at [email protected].",
labels,
threshold=0.5,
)
2. Cached incremental session
session_id = "call-42"
for chunk in [
"Customer Jane",
" Doe asked us to call",
" +1 (415) 555-0132.",
]:
snapshot = model.inference(
[chunk],
labels,
session_id=[session_id],
threshold=0.5,
)[0]
print(snapshot)
3. Full-session recompute
# The next chunk must be non-empty. This reruns all accumulated text
# and also permits a changed label set.
final_labels = labels + ["account number"]
final_snapshot = model.inference(
[" Account 12345678 was also mentioned."],
final_labels,
session_id=[session_id],
recompute=True,
threshold=0.5,
)[0]
model.clear_session(session_id)
Streaming details:
- Each call returns the complete current session snapshot , not only new entities.
- Chunks are concatenated verbatim; preserve boundary spaces and punctuation.
- Offsets refer to the complete accumulated text.
-
Keep labels fixed unless using
recompute=True; always clear finished sessions.
Evaluation
PIIMB ranking scores are label-agnostic, character-level masking metrics. They are micro-averaged within each task; group rows are unweighted averages across tasks. F2 is primary because it weights recall more heavily. Strict NER F1 also requires matching entity boundaries and type.
| Scope / task | Precision | Recall | Masking F1 | Masking F2 | FPR | Strict NER F1 |
