+# Runs the real privacy-filter GGUF NER tier end-to-end on CPU — the gap the
+# hermetic tests/e2e suite cannot cover (it only exercises the in-process
+# pattern tier). Heavy (builds the C++ backend image + downloads a ~2.7 GB
+# GGUF), so it is path-filtered on PRs and otherwise runs nightly / on demand.
+#
+# This drives the container-level harness (tests/e2e-backends) via
+# `make test-extra-backend-privacy-filter`: it builds the privacy-filter image,
+# downloads the model, loads it on CPU, and asserts byte-correct, UTF-8-aligned
+# TokenClassify spans. The complementary HTTP-path specs in tests/e2e
+# (e2e_pii_ner_test.go) Skip unless PII_NER_MODEL_GGUF is wired.

+
+    ## Introduction
+
+    We're introducing GLM-5.2, our latest flagship model for long-horizon tasks. It marks a substantial leap in long-horizon task capability over its predecessor GLM-5.1 and, for the first time, delivers that capability on a **solid 1M-token context**. GLM-5.2's new capabilities include:
+      - **Solid 1M Context:** A solid 1M-token context that stably sustains long-horizon work
+      - **Advanced Coding with Flexible Effort**: Stronger coding capabilities with multiple thinking effort levels to balance performance and latency
+      - **Improved Architecture**: We propose IndexShare, which reuses the same indexer across every four sparse attention layers, reducing per-token FLOPs by 2.9× at a 1M context length. We also improve GLM-5.2’s MTP layer for speculative decoding, increasing the acceptance length by up to 20%
+      - **Pure Open**: An MIT open-source license — no regional limits, technical access without borders

+    A fine-grained English PII token-classification model: a fine-tune of
+    openai/privacy-filter by OpenMed on NVIDIA's Nemotron-PII dataset. It labels
+    every token with a BIOES tag over 55 PII categories (221 classes), trading
+    the multilingual sibling's language breadth for category depth - identity,
+    contact, address, dates, government IDs, financial, healthcare, enterprise,
+    vehicle and digital entities (including api_key, ipv4/ipv6 and mac_address).
+    For multilingual text prefer privacy-filter-multilingual instead.
+
+    In LocalAI this is a PII detector for the NER redactor tier: set
+    known_usecases to [token_classify] (as below), and any model opts into
+    redaction by listing this one under pii.detectors. The detection policy
+    (which categories to mask vs block, and the score threshold) lives on this
+    model's own pii_detection block - see the overrides below. It runs locally
+    with no Python, served by the standalone privacy-filter backend's
+    TokenClassify RPC (constrained BIOES Viterbi decode into UTF-8 byte-offset
+    entity spans).
+
+    Architecture: gpt-oss-style sparse MoE (8 layers, d_model 640, 128 experts
+    top-4, ~1.5B total / ~50M active per token), bidirectional banded attention,
+    o200k tokenizer and a 221-way token-classification head; served via the
+    openai-privacy-filter architecture. F16, ~2.8 GB. (A smaller Q8_0 quant
+    exists on the GGUF repo for RAM-constrained use - validate it on your own
+    data, since for PII a single dropped span is a leak.)
