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)
🔹 **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)
🔹 **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)
🔹 **Weak CPU & Browser:** single-thread, N100-class, WASM 1 thread, quantized INT8, <500MB RAM, cold start 0.4s (INT8)
🔹 **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). ### Datasets (96k → 110k Guard, 53k PII, RU/EN, modern) | Dataset | Used | Total | OWASP 2025-2026 coverage | Lang | HF ID | |-----------------------------------|------------------------------------------|---------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------|----------------------------------------------------------------| | **shieldlm** | 54,162 (37,913 train / 8k val / 8k test) | 54k | LLM01 S1-S9: direct, indirect, S3 encoding, typoglycemia, best-of-n, html_markdown, agent_specific, persistent - 11 sources | EN + FR/DE/ES/IT/PT/RO/CA | `Abdennebi/shieldlm-prompt-injection` Apache-2.0 | | **Agentic synthetic** | 22,500 | 22.5k | LLM01-10 2026 + Agentic Top10: Goal Hijack, Privilege Abuse, Code Exec, InterAgent, Trust, Tool Misuse, Supply Chain, Memory Poisoning, Cascading, Rogue, Policy Puppetry, EchoLeak, Lies-in-the-Loop, Vector, Excessive Agency, Misinformation, Unbounded Consumption, Sensitive Disclosure, Improper Output | RU/EN | `training/synth_datasets.py` | | **Modern obfuscation** | 14,072 | 14k | base64 25%, zw 15%, homoglyph 15%, spaced 15%, control tokens 15%, indirect JSON 15% - **2024-2026 methods**, bilingual | RU/EN | `training/train_large_ogl_mini.py` generate_modern_obfuscation | | **custom-collected-dataset 300k** | 30,000 | 300k | PII 19 types → 11 mapped: EMAIL, PHONE (TEL), PERSON (GIVENNAME/LASTNAME/USERNAME), IP, IBAN, BANK_CARD, PASSPORT, GOV_ID (IDCARD/SOCIALNUMBER/DRIVERLICENSE), DOB (BOD/DATE/TIME), ADDRESS (STREET/CITY/BUILDING/STATE/POSTCODE), SOCIAL | EN | - | | **custom-collected-dataset 1M** | 15,000 | 1.4M | same 19 types, 23 lang | multilingual | - | | **Synthetic RU/EN PII** | 8,000 | - | PERSON RU/EN, EMAIL, PHONE +7 8-800, IBAN RU/DE, PASSPORT, ADDRESS RU, GOV_ID, DOB | RU/EN | - | | **Guard total** | **110,734** (49k attack / 61k benign) | - | 22 OWASP cats, RU/EN, modern 2024-2026 | RU/EN | - | | **PII total** | **53,000** (40k PII / 12k benign) | 53k | 11 labels micro F1 0.86 | RU/EN + FR/DE/ES | - | | *Additional* | - | 175k gravitee, 100k Nemotron, 5.6k prodnull | PII/Injection | EN | - | ### Evaluation (hold-out, thr 0.60) | Metric | Target | **Guard FP32 250MB** | **Guard INT8 2.79MB (same data)** | **PII 3.67MB** | |----------------------------------------------------------------------------------|--------|----------------------------|-----------------------------------|---------------------------------------------------------------------------------------------------------| | AUC / F1 | - | **0.997** AUC, 0.98 F1 | **0.997** (quantized, same) | **0.86 micro** F1 (0.99 EMAIL, 0.86 PHONE, 0.82 PERSON, 0.85 IP, 0.94 DOB) → **hybrid regex+ONNX 0.95** | | LLM01 direct+indirect recall | ≥90% | **98%** (94123 train) | **98%** | - | | Jailbreak recall | ≥85% | **100%** | **100%** | - | | Policy Puppetry / Hidden / Goal Hijack / Obfuscation (incl. base64/zw/homoglyph) | - | **100%** | **100%** | - | | PII F1 RU/EN 11 types | ≥0.85 | - | - | **0.86** micro | | FPR benign 30 + 120 extended RU/EN | <2% | **0%** | **0%** | 0% | | Confidence | - | `risk 0-1 + label + stage` | same | `score 0-1 + type` | --- ## 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 ``` --- ## License - MIT License for model. - **Datasets:** shieldlm Apache-2.0, pii-masking CC-BY-4.0, Nemotron NVIDIA. --- ## Citation ```bibtex @misc{oglmini2026, title={OGL-Mini: Hybrid Guard for AI Agents (OWASP 2025-2026, RU/EN, Weak CPU + Browser)}, author={Elijah Rastorguev}, year={2026}, url={https://huggingface.co/devsdaddy/ogl-mini}, note={Guard 110k (shieldlm 54k + agentic 22.5k + modern 14k) + PII 53k (custom-collected-dataset 30k + openpii 15k), Guard AUC 0.997, PII F1 0.86} } ```
