OpenAI Codex

OpenAI Codex is an artificial intelligence model developed by OpenAI. It parses natural language and generates code in response. It is used to power GitHub Copilot, a programming autocompletion tool. Codex is a descendant of OpenAI's GPT-3 model, fine-tuned for use in programming applications. OpenAI has released an API for Codex in closed beta. Based on GPT-3, a neural network trained on text, Codex has additionally been trained on 159 gigabytes of Python code from 54 million GitHub repositories.

KYC Agent

KYC Agent

KYC Agent is an intelligent, end-to-end Know-Your-Customer compliance platform built for Deriv. It replaces slow, manual document verification with AI-driven automation while keeping humans in the loop for high-risk cases. How it works: Users upload country-specific identity documents (CNIC, Emirates ID, Passport, Aadhaar/PAN) and proof-of-address through a guided multi-step onboarding wizard. Google Gemini 2.5 Flash performs real-time OCR extraction and document quality analysis — detecting 20+ issues like blur, glare, cropped corners, and potential manipulation. Extracted data is cross-validated against user-submitted form fields to catch mismatches and inconsistencies. Hybrid Risk Scoring Engine: A two-tier risk assessment combines deterministic rule-based checks (data mismatches, expired documents, missing fields, name inconsistencies with transliteration awareness) with Gemini-powered AI analysis for nuanced fraud detection. Submissions are auto-routed: LOW risk → auto-approved, MEDIUM → manual review queue, HIGH → flagged for expert review. Compliance Dashboard: An internal admin tool gives compliance officers a real-time queue of submissions with risk-sorted views, side-by-side form-vs-OCR comparison, detailed risk factor explanations, and one-click approve/reject actions with audit trail notes. Key differentiators: Country-aware intelligence with side-specific OCR (e.g., CNIC back = address extraction) Explainable risk scores — every flag comes with reasoning and severity Graceful Deriv WebSocket API integration with demo-mode fallback Production-grade architecture (FastAPI + Streamlit) with zero external infrastructure dependencies Built with: Streamlit, FastAPI, Google Gemini 2.5 Flash, Deriv WebSocket API, Pydantic, Python

CAREN - AI-Powered Financial Crime Detection

CAREN - AI-Powered Financial Crime Detection

CAREN (Credit Analysis & Risk Evaluation Network) is a next-generation AI-powered transaction monitoring system designed to detect financial crimes in real-time while dramatically reducing false positives that overwhelm compliance teams. The system employs an ensemble of five machine learning models—XGBoost, Random Forest, Logistic Regression, K-Nearest Neighbors, and AdaBoost Decision Tree—trained on anonymized PCA-transformed transaction features (V1-V28). This architecture achieves 99.94% accuracy, 94.12% precision, and 81.63% recall, with an AUC-ROC of 98.21%. Key capabilities include: • Real-time fraud scoring with sub-50ms latency per transaction • Intelligent alert prioritization that turns thousands of weekly alerts into high-confidence cases • Multi-dimensional risk analysis combining velocity patterns, geographic anomalies, and amount deviations • Visual investigation dashboard with transaction timelines and evidence summaries • Configurable detection thresholds for different risk appetites The platform features a comprehensive dashboard for fraud analysts with live transaction monitoring, severity-based alert management, ML model performance analytics, and an AI-powered fraud analyzer that explains predictions using feature importance visualization. Built for scale, CAREN processes transactions in real-time and provides actionable intelligence that reduces investigation time from hours to minutes while maintaining the highest detection accuracy.
