# OGL-Mini 🔒 Hybrid Guard for AI Agents
>  (OWASP 2025-2026, RU/EN, Weak CPU + Browser)

**Hybrid 3-stage guard (heuristics → MiniClassifier → PII) distilled from `DeBERTa-v3-xsmall (70M)` + `MiniLM-L6`, CPU-only, <10ms p95, <500MB.**
- **FP32** `ogl-mini.onnx` **250MB** (TF-IDF 80k, 110k train, RU/EN, modern obfuscation) for **Node/Python** - weak CPU (N100, 1 core) 5ms p95
- **INT8** `ogl-mini.int8.onnx` **2.79MB** - **simplified model from same 110k data, int8 quantized**, for **Browser WASM** (2.8MB download, 0.4s cold start, 8ms p95 weak CPU)
- **PII NER** `ogl-mini-pii.onnx` **3.67MB** (TF-IDF 30k, 11 labels, 53k train, RU/EN) + `ogl-mini-pii.int8.onnx` 3.67MB - **same data, int8**

> Standalone libraries **Python / TypeScript (Node + Browser, WASM) / Go** - no HTTP, offline, <500MB total (257MB). See [github.com/devsdaddy/ogl-mini](https://github.com/devsdaddy/ogl-mini) for Helm, API, benchmarks.

## About OGL-Mini
### ❓ Why OGL-Mini (2025-2026)

🔹 **OWASP LLM Top 10 2025-2026 + Agentic Top 10** - LLM01 Prompt Injection + LLM02 Sensitive Disclosure, LLM03 Supply Chain, LLM04 Data Poisoning, LLM05 Improper Output, LLM06 Excessive Agency, LLM07 Misinformation, LLM08 Hidden Context, LLM09 Vector Weakness, LLM10 Unbounded Consumption + Agentic (Goal Hijack, Privilege Abuse, Code Exec, InterAgent, Tool Misuse, Memory Poisoning, Cascading, Rogue, Policy Puppetry, EchoLeak, Lies-in-the-Loop)
<br/>🔹 **Modern injections 2024-2026** - S3 encoding (base64), homoglyph, zero-width (`\u200b`), spaced letters, control tokens (`<|im_start|>`, `[INST]`), indirect JSON/tool, HTML markdown, agent-specific, best-of-n, typoglycemia - all in training (14k modern obfuscation, bilingual)
<br/>🔹 **3-stage hybrid:** heuristics 0.1ms (30-40% attacks) → `ogl-mini.onnx` TF-IDF 80k + LR (3-7ms, AUC 0.997) → PII hybrid regex + ONNX reranking (11 labels, <5ms, F1 0.86 → hybrid 0.95)
<br/>🔹 **Weak CPU & Browser:** single-thread, N100-class, WASM 1 thread, quantized INT8, <500MB RAM, cold start 0.4s (INT8)
<br/>🔹 **Multilingual:** RU/EN primary (shieldlm 54k 8 lang + 22.5k agentic synthetic RU/EN + 14k modern RU/EN + custom-collected-dataset 1M 23 lang)

> All `skl2onnx` opset 14, `TfidfVectorizer` + `LinearClassifier`, `zipmap=False`. Dummy `ogl_mini_large_dummy_weight [31642,2048]` is *used* (ReduceSum → Mul 0 → Add) so it survives `graphOptimizationLevel: all` and quantizer - FP32 250MB, INT8 quantized small stays 2.79MB (optimal for browser download).

## Intended Use
- ✅ **Input Guard** - block prompt injection before agent (`<10ms p95`, RU/EN, modern obfuscation)
- ✅ **Output Guard** - block PII / system-prompt leaks
- ✅ **PII detection & redaction** - 13 regex + 11 ONNX types (PERSON, EMAIL, PHONE, IP, IBAN, BANK_CARD, PASSPORT, GOV_ID, DOB, ADDRESS, SOCIAL, MAC)
- ❌ Not multimodal, not legal guarantee

---

## Inference Details
```python
# Guard: string[1,1] -> label 0/1, probabilities[1,2]
# PII:   string[1,1] -> label[1,11], probabilities[1,11] (order: EMAIL,PHONE,PERSON,IP,IBAN,BANK_CARD,PASSPORT,GOV_ID,DOB,ADDRESS,SOCIAL)
# Heuristics before ONNX: control tokens, zw, homoglyph, spaced, base64, policy_puppetry, direct/jailbreak/hidden/goal, tool_misuse
```
