Inference API

Console inference serves OpenAI, Anthropic, and Gemini-compatible APIs from https://opencode.ai/inference. Send a JSON POST request to the endpoint that matches the model’s API family.

curl -X POST "https://opencode.ai/inference/openai/v1/chat/completions" \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "kimi-k3",
    "messages": [{ "role": "user", "content": "Say hi" }]
  }'

Authentication

Replace <token> with a personal API key or a service account key created in the Console. Paid models require the header. Free-tier chat models are only available from within OpenCode; other clients receive HTTP 403, even with an API key. Use paid models or a Go subscription from other clients.

Authorization: Bearer <token>

Endpoints

Each model is served by one API family. See the model endpoints table, or fetch the live list:

curl https://opencode.ai/inference/v1/models

OpenAI Chat Completions

Open models such as kimi-k3, glm-5.3, minimax-m3, and the free models use the Chat Completions API.

curl -X POST "https://opencode.ai/inference/openai/v1/chat/completions" \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "glm-5.3",
    "messages": [{ "role": "user", "content": "Say hi" }]
  }'

OpenAI Responses

GPT models use the Responses API.

curl -X POST "https://opencode.ai/inference/openai/v1/responses" \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-6.1-sol",
    "input": "Say hi"
  }'

Anthropic Messages

Claude and Qwen models use the Messages API. max_tokens is required.

curl -X POST "https://opencode.ai/inference/anthropic/v1/messages" \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-sonnet-5-5",
    "max_tokens": 1024,
    "messages": [{ "role": "user", "content": "Say hi" }]
  }'

Gemini

Gemini models take the model and method in the path. Replace :generateContent with :streamGenerateContent to stream the response.

curl -X POST "https://opencode.ai/inference/google/v1beta/models/gemini-4-argon:generateContent" \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{
    "contents": [{ "parts": [{ "text": "Say hi" }] }]
  }'
