+
+**Kyo-Instruct** is an ultra-fast (140M parameter) **System-One semantic routing and policy gating engine** engineered to govern autonomous AI agents, tool selection, and high-throughput intent pipelines in real time.
+
+Fine-tuned directly on top of **`open-zzrl/kyo`** using multi-domain Experience Replay, Kyo-Instruct bridges the gap between deterministic typed policy Instruct and generalized natural language intent classification. Powered by a specialized **Dual-Pooling Cross-Encoder head** (`[CLS]` + Masked Mean to 768d over a ModernBERT backbone), it delivers sub-10ms deterministic execution with **99.95% order-invariance**, outperforming models 3× its size.
+
+* **GitHub Repository:** [github.com/open-zzrl/kyo](https://github.com/open-zzrl/kyo)
+* **Developed by:** constructai & zait-ai (`open-zzrl`)
+* **Base Model:** `open-zzrl/kyo`
+* **Underlying Backbone:** `jhu-clsp/mmBERT-small` (ModernBERT encoder, 12 layers, hidden size 384)
+* **Context Window:** Up to 4096 tokens (native RoPE + SDPA)
+* **Average Inference Latency:** 8.80 ms (P95: 9.71 ms on CUDA, `bfloat16`)
+* **Memory Footprint:** ~280 MB VRAM (< 1.5 GB peak with runtime context)

+
+### 2. Detailed Performance Analysis
+
+* **99.95% Order-Invariance:** Autoregressive models and standard classification heads suffer severe position bias when candidate options are shuffled. Kyo isolates candidate scoring pairs, guaranteeing decisions remain stable regardless of input option order.
+* **Full-Scale Candidate Evaluation:** On Banking77, Kyo processes all **77 candidates simultaneously** per pass with 12.18 ms latency, eliminating the need to pre-filter options.
+* **Weight Efficiency:** At 140M parameters, Kyo-Instruct exceeds the 421M parameter Laya by **+12.05%** on emotion classification and **+5.06%** on fine-grained banking intent routing.

+
+### Upgrading to Latest Release
+
+```bash
+pip install --upgrade --no-cache-dir --force-reinstall git+[https://github.com/open-zzrl/kyo.git](https://github.com/open-zzrl/kyo.git)
+
+```
+
+> **Requirements:** Python ≥ 3.9, PyTorch ≥ 2.0 with CUDA support, and `git`.
+
+---
+
+## 🚀 Quickstart
+
+Kyo loads pre-trained weights, tokenizer configurations, and execution parameters directly from Hugging Face Hub:
+
+```python
+import torch
+from kyo import Kyo
+
+# 1. Initialize the engine
+engine = Kyo.from_pretrained("open-zzrl/kyo-instruct", confidence_threshold=0.80)
+
+# ==========================================
+# Scenario A: Autonomous Agent Policy & Safety Gating
+# ==========================================
+telemetry = {
+    "agent_id": "payment-worker-4",
+    "endpoint": "/api/v1/transfer/batch",
+    "requested_amount_usd": 145000,
+    "spending_limit_usd": 50000,
+    "user_approval_present": False,
+    "geo_anomaly": True
+}
+
+safety_Instruction = "Verify transaction safety against corporate treasury compliance rules."
+safety_options = {
+    "Allow": "Transaction within limits and conforms to standard policy.",
+    "Require2FA": "Minor anomaly; hold for secondary automated factor.",
+    "BlockAndEscalate": "Hard limit breach or suspicious telemetry; freeze and alert human."
+}
+
+# Warm-up (initializes CUDA context and JIT-compiles SDPA kernels)
+_ = engine.decide(context=telemetry, Instruction=safety_Instruction, options=safety_options)
+
+result_safety = engine.decide(
+    context=telemetry,
+    Instruction=safety_Instruction,
+    options=safety_options
+)
+
+print("-" * 55)
+print(f"Safety Decision    : {result_safety.decision}")
+print(f"Confidence         : {result_safety.confidence * 100:.2f}%")
+print(f"Hot Latency        : {result_safety.latency_ms:.2f} ms")
+print(f"Requires Fallback  : {result_safety.fallback_to_llm}")
+
+# ==========================================
+# Scenario B: Dynamic Semantic Intent Classification
+# ==========================================
+customer_query = "Why is my card balance still unchanged after I deposited cash at the ATM two hours ago?"
+routing_Instruction = "Classify customer inquiry into the matching operational queue."
+routing_options = {
+    "atm_deposit_pending": "Delays or missing balance updates after ATM cheque or cash deposit.",
+    "wire_transfer_delay": "Inbound or outbound international wire transfer pending.",
+    "compromised_card": "Card reported stolen, cloned, or fraudulent charges detected.",
+    "order_physical_card": "Requesting delivery of a new physical replacement card."
+}
+
+result_route = engine.decide(
+    context=customer_query,
+    Instruction=routing_Instruction,
+    options=routing_options
+)
+
+print("-" * 55)
+print(f"Routed Queue       : {result_route.decision}")
+print(f"Confidence         : {result_route.confidence * 100:.2f}%")
+print(f"Latency            : {result_route.latency_ms:.2f} ms")
+print("-" * 55)
+
+```

+
+## 🎯 Intended Use & Boundaries
+
+### ✅ What Kyo Excels At (In Scope)
+
+* **Agent Security Guardrails & Policy Gating:** Evaluating execution traces, payloads, and parameter states against programmatic guardrails (`noul` accuracy: **82.33%**).
+* **Deterministic Tool & Action Routing:** Dynamic selection of functions, endpoints, or execution paths from candidate options (**69.50%** on structured choices, **47.56%** across 77 simultaneous intents).
+* **Real-Time Stream Routing:** Intent categorization and customer support triage under strict latency constraints (< 10 ms).
+* **Cost-Efficient Frontier LLM Offloading:** Calibrated confidence scoring identifies uncertain predictions (`result.fallback_to_llm = True`), routing only ambiguous requests to costly generative LLMs.
+
+### ❌ Out of Scope
+
+* **Open-Ended Autoregressive Generation:** Kyo is a pure discriminator/cross-encoder, not a generative language model.
+* **Relational Multi-Column Spreadsheet Arithmetic:** Complex numerical calculations over dense tabular formats require specialized math reasoning models or large frontier LLMs.
+
+---
+
+## 🧠 Architecture: Dual-Pooling Pairwise Cross-Encoder
+
+Kyo scores each candidate option $k$ in parallel against the shared query context:
+
+$$\text{Features}_k = \text{LayerNorm}\Big(\big[\mathbf{h}_{\text{CLS}} \,\Vert\, \text{MeanPool}(\mathbf{H}_{\text{tokens}})\big]\Big) \in \mathbb{R}^{768}$$
+
+$$\text{Score}_k = \mathbf{W}_2 \cdot \text{GELU}(\mathbf{W}_1 \cdot \text{Features}_k)$$
+
+```text
+[Context + Instruction] ──┐
+                          ├──> [mmBERT-small (12L, 384d)] ──> [CLS (384d)] ────────┐
+[Candidate Option (k)] ───┘                                   [Mean Pool (384d)] ──┴─> LayerNorm (768d) ──> MLP Head ──> Logit_k
+
+```
+
+1. **Pairwise Isolation:** Evaluates each candidate independently against the context, eliminating candidate-order positional bias and guaranteeing **99.95% order-invariance**.
+2. **Dual Representation:** Concatenating global contextual attention (`[CLS]`) with dense token coverage (masked mean pooling) doubles representation capacity without increasing encoder FLOPs.
+
+---
+
+## 🛠️ Environment & Optimization Notes
+
+* **Native `bfloat16` Calibration:** Kyo is natively trained and calibrated in `bfloat16`. Do not wrap evaluation in standard fp16 `GradScaler`.
+* **Latency Profile:**
+* **Cold Start (Run 1):** ~1.0–1.4s (CUDA context initialization and PyTorch SDPA kernel compilation).
+* **Warm Inference (Run 2+):** **8.80 ms** average (P95: **9.71 ms**).
+
+
+
+### Python 3.13 & Vision Dependencies Note
+
+Kyo is an encoder-based text decision engine and does not use vision or audio models. If your environment encounters ABI issues with `torchvision` (e.g. `RuntimeError: operator torchvision::nms does not exist`), you can safely strip vision libraries:
+
+```bash
+pip uninstall -y torchvision torchaudio torchao
+
+```
