AI Chat Assistant

AI-powered chat assistant using GPT-4 API with context awareness, multi-language support, and custom training capabilities.

AI Chat Assistant - Machine Learning Application

Overview

AI Chat Assistant is a multi-channel assistant built on GPT-4 with strong guardrails and a clean UX. The goal was to deliver helpful answers while keeping behavior predictable for both users and administrators.

Focus: context quality, safety, and latency. Audience: customer support + internal knowledge workflows.

Capabilities

  • Context awareness: session memory + retrieval snippets
  • Multi-language: 15+ languages with locale-aware formatting
  • Tools: knowledge search, ticket creation, and link suggestions
  • Admin: prompt templates, policy rules, and analytics

System design

The backend is built with FastAPI and containerized with Docker. Requests are structured, validated, and traced to keep responses consistent.

  1. Prompt orchestration: system rules + user intent + retrieved context
  2. Safety: refusal paths and safe completion patterns
  3. Performance: streaming responses and caching for common intents

Evaluation & iteration

I set up lightweight evaluations to prevent regressions: golden prompts, intent coverage checks, and qualitative reviews. Documentation includes example prompts with bold constraints, tone guidance, escalation rules, and clickable references.

Links: product spec, evaluation notes, and demo.
