| # 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) |
|
|
| ### Tiny and Fast Models (all <500MB, same data FP32 vs INT8) |
|
|
| | File | Size | Training data | Use | Input → Outputs | |
| |--------------------------|-----------------|------------------------------------------------------------------------------|----------------------------------|--------------------------------------------------------------------------------------| |
| | `ogl-mini.onnx` | **250MB FP32** | **110,734** (shieldlm 54k + agentic 22.5k + modern 14k + pii benign 15k) | **Node/Python, weak CPU** | `string[1,1]` `input` → `label` 0/1, `probabilities` float[1,2] (P attack = prob[1]) | |
| | `ogl-mini.int8.onnx` | **2.79MB INT8** | same data 110k, `QuantType.QInt8` | **Browser WASM**, weak CPU, edge | same | |
| | `ogl-mini.pkl` | 3.8MB | same | Python fallback | `sklearn` pipeline | |
| | `ogl-mini-pii.onnx` | **3.67MB FP32** | **53,000** (custom-collected-dataset 30k + openpii 15k + synthetic RU/EN 8k) | **Node/Browser WASM** | `string[1,1]` → `label[1,11]`, `probabilities[1,11]` 11 labels | |
| | `ogl-mini-pii.int8.onnx` | **3.67MB INT8** | same 53k | Browser WASM | same | |
| | `pii.onnx` | 354KB | same 53k binary has_pii | gate | same → float P(has_pii) | |
|
|
| > 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 |
