AI Gateway (aig)

Self-hosted, OpenAI-wire-compatible AI gateway that calls model providers directly, with a custom enrichment layer with first-class Iran/Persian support.

Architecture

Customer ──► AI Gateway (FastAPI) ──► model provider ──► OpenRouter / local vLLM / RAG

AI Gateway handles: enrichment pipeline (datetime, calendar, system prompt, tool packs), auth caching, audit logging, Telegram alerts. the provider handles: provider routing, fallback, budgets, virtual keys, spend tracking.

Prerequisites

• Docker & Docker Compose v2
• Python 3.12 + uv
• Postgres 16 (external for prod; bundled in dev compose)

Quick Start

Dev mode: the gateway itself is not containerised right now — the aig service is commented out of docker-compose.yml / docker-compose.dev.yml so it can be edited and restarted freely. It runs on the host with uvicorn --reload; only its dependencies (Postgres, Redis, MinIO, Prometheus) stay in Docker and publish their ports on localhost.

# 1. Clone and install
git clone <repo>
cd ai-gateway
uv sync --dev

# 2. Configure
cp .env.example .env
cp .env.example .env
# Edit both files — at minimum set passwords and API keys.
# Leave the in-cluster host names (db, redis, minio) as they are:
# `make dev` overrides them with localhost equivalents at run time.

# 3. Start the dependencies
make up

# 4. Migrate + seed (catalog, free models, admin user) — idempotent
make bootstrap

# 5. Run the gateway with hot-reload
make dev

# 6. Verify (in another terminal)
curl http://localhost:8000/healthz   # → {"status":"ok"}
curl http://localhost:8000/readyz    # → {"status":"ok"} once the DB and catalog are up

One-shot equivalents that do all of the above: scripts/win/run-dev.bat (Windows) or scripts/sh/run-dev.sh (Linux/macOS). To bring the gateway back into Docker, uncomment the aig service in both compose files and use make up-prod.

Admin UI

the provider's built-in admin UI is available at https://openrouter.ai/api/v1/ui once the stack is up. See Operations — Admin UI for login, roles, and security notes.

Development

make install    # install deps (uv sync --dev)
make dev        # run the gateway on the host with hot-reload (:8000)
make bootstrap  # migrations + all seeds
make lint       # ruff
make typecheck  # mypy
make test       # pytest
make coverage   # with HTML report at htmlcov/
make ci         # all gates
