[GoModel on Hacker News]

GoModel is the fastest and the most resource-efficient AI Gateway (the self-reproducible benchmarks). It's an alternative to LiteLLM (which was hacked recently) and Portkey (which is no longer maintained on GitHub).

GoModel saves you money and nerves.

Money - because you can remember the responses on this layer (caching), track your spending and do tricks like prompt compression and intelligent routing.

Nerves - because we strive to achieve good quality and reliability. Our ambition is to be the last AI gateway you will need - the most reliable, resource-optimal, feature-rich and fast.

Quick Start

Step 1: Install and start GoModel

Docker

docker run --rm -p 8080:8080 \  -v gomodel_data:/app/data \  enterpilot/gomodel

macOS / Linux

curl -fsSL https://gomodel.enterpilot.io/install.sh | sh# OPENAI_API_KEY="your-openai-key" # (optional)gomodel

Windows (PowerShell)

irm https://gomodel.enterpilot.io/install.ps1 | iex# $env:OPENAI_API_KEY = "your-openai-key" # (optional)gomodel

ℹ️ Configure GoModel with .env, a config.yaml file, or manage the most important settings directly in the dashboard.

ℹ️ See .env.template for the complete list of environment variables, including all available providers.

Step 2: Open the dashboard and add a provider

http://localhost:8080/admin/dashboard

Step 3: Make an API call

curl http://localhost:8080/v1/responses \  -H "Content-Type: application/json" \  -d '{    "model": "gpt-5-chat-latest",    "input": "Hello!"  }'

GoModel and official SDKs

GoModel accepts requests in two compatible formats:

• OpenAI-compatible at /v1
• Anthropic-compatible at /v1/messages

The official SDKs therefore work unchanged. Configure their base URLs as follows:

• OpenAI SDK: http://localhost:8080/v1
• Anthropic SDK: http://localhost:8080 (the SDK appends /v1/messages)

Docker Compose

Infrastructure only (Redis, PostgreSQL, MongoDB, Adminer - no image build):

cp .env.template .env# Add your API keys to .envdocker compose up -d# or: make infra

Full stack (adds GoModel + Prometheus; builds the app image):

docker compose --profile app up -d# or: make image

• API Endpoints
• Admin API Endpoints

Gateway Configuration

GoModel resolves configuration in the following order, with each source overriding those to its left:

Good defaults → config.yaml → .env → exported environment variables

See the Configuration reference for the full list of settings.

Features

• Caching - exact and semantic response caching, so repeated prompts cost nothing
• Cost tracking - per-request cost estimates, usage analytics, and spending breakdowns in the dashboard
• Budgets - hard spend limits per user, team, or key
• Rate limits - requests, tokens, and concurrency caps per user path, provider, or model
• Usage API - clients check their own usage, remaining budget, and rate-limit headroom with the key they already use for inference
• Virtual models - aliases and load balancing (round-robin or cost-based) behind stable model names
• Session keeping - detect a client session and pin it to one target and provider key, so provider prompt caches stay warm and audit logs read as threads
• Failover - automatic rerouting to backup providers, with retries and circuit breakers
• Labelling - tag requests from HTTP headers or API keys and break down usage by label
• User paths - hierarchical scoping of keys, model access, budgets, usage, and audit logs
• Model access control - per-group, per-user, and per-key model allowlists that intersect down the user-path tree
• MCP gateway - aggregate your MCP servers behind one authenticated endpoint
• Passthrough API - provider-native APIs under /p/{provider}/..., with GoModel auth and tracking
• Audio and image APIs - OpenAI-compatible text-to-speech, transcription, and image generation and editing with the same access rules, budgets, and cost tracking as chat
• Provider replay state - preserves Gemini thought signatures and Anthropic thinking blocks across turns, APIs, and providers
• Guardrails - request and response policies enforced at the gateway
• Plugins - one contract for guardrails, response and stream filters, header edits, and routing strategies; built in, compiled in, or loaded from a .so at startup
• Workflows - versioned per-request policies that scope cache, budgets, audit logging, guardrail phases, and failover by user path, provider, or model
• Provider key rotation - round-robin over multiple API keys to lift per-key rate limits
• Observability - Prometheus metrics, OpenTelemetry traces, audit logs, and live request streaming in the dashboard
• Playground - try any model or virtual model from the dashboard and inspect the exact request and response JSON

GoModel Pro

GoModel Pro is the commercial build: the same gateway, configuration, and dashboard, with licensed extensions.

• Prompt compression - remove repeated and structural context before it reaches the provider, without changing the request shape
• Intelligent routing - classify each request as easy or hard, then pick the healthiest and cheapest provider in that tier
• OIDC single sign-on - protect the dashboard with your identity provider using Authorization Code flow with PKCE
