Show HN: GoModel – an open-source AI gateway in Go

A high-performance AI gateway written in Go, providing a unified OpenAI-compatible API for OpenAI, Anthropic, Gemini, xAI, Groq, OpenRouter, Z.ai, Azure OpenAI, Oracle, Ollama, and more.

Step 1: Start GoModel

docker run --rm -p 8080:8080 \
-e LOGGING_ENABLED=true \
-e LOGGING_LOG_BODIES=true \
-e LOG_FORMAT=text \
-e LOGGING_LOG_HEADERS=true \
-e OPENAI_API_KEY="your-openai-key" \
enterpilot/gomodel

Pass only the provider credentials or base URL you need (at least one required):

docker run --rm -p 8080:8080 \
-e OPENAI_API_KEY="your-openai-key" \
-e ANTHROPIC_API_KEY="your-anthropic-key" \
-e GEMINI_API_KEY="your-gemini-key" \
-e GROQ_API_KEY="your-groq-key" \
-e OPENROUTER_API_KEY="your-openrouter-key" \
-e ZAI_API_KEY="your-zai-key" \
-e XAI_API_KEY="your-xai-key" \
-e AZURE_API_KEY="your-azure-key" \
-e AZURE_BASE_URL="https://your-resource.openai.azure.com/openai/deployments/your-deployment" \
-e AZURE_API_VERSION="2024-10-21" \
-e ORACLE_API_KEY="your-oracle-key" \
-e ORACLE_BASE_URL="https://inference.generativeai.us-chicago-1.oci.oraclecloud.com/20231130/actions/v1" \
-e ORACLE_MODELS="openai.gpt-oss-120b,xai.grok-3" \
-e OLLAMA_BASE_URL="http://host.docker.internal:11434/v1" \
enterpilot/gomodel

For production, use docker run --env-file .env to load API keys from a file instead.

Step 2: Make your first API call

curl http://localhost:8080/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{
"model": "gpt-5-chat-latest",
"messages": [{"role": "user", "content": "Hello!"}]
}'
