Flagship GLM model for long-horizon coding, agents, and complex project delivery
OpenCode Go is a model service from the OpenCode team that gives you one API key for 30+ curated coding models, including DeepSeek V4, Qwen3.8, GLM-5.3, Kimi K3, MiMo, MiniMax, and Grok, billed per token.
Most models use an OpenAI-compatible Chat Completions endpoint, while the GPT, Grok, and Muse Spark models use the OpenAI Responses API.

Complete Setup Guide
Get Your OpenCode Go API Key
First, you'll need to obtain an API key from OpenCode Go. This key allows you to access their AI models directly and pay only for what you use.
- Visit OpenCode Go's API console
- Sign up or log in to your account
- Navigate to the API keys section
- Generate a new API key (copy it immediately as some providers only show it once)
- Save your API key in a secure password manager or encrypted note
Sometimes, this provider will require you to add a payment method to your account before you can use your API key to chat with AI. So, to avoid any hiccups, make sure you've got a payment method set up and ready to go!
Important: Keep your API key secure and never share it publicly. Store it safely as you'll need it to connect with TypingMind.
Configure TypingMind with OpenCode Go API Key
Option 1: Use the built-in OpenCode Go provider (recommended)
The quickest way. TypingMind already has OpenCode Go set up, so you only need to add your API key.
- Open TypingMind and click "Models" in the left sidebar.
- Search for OpenCode Go.
- Click the settings (gear) button next to OpenCode Go.
- Paste your API key and save.
Option 2: Add the model manually
If you can't find the provider or model ID in the official list, you can add the model manually:
Open the Models page
Open TypingMind, click "Models" in the left sidebar, then click "Add custom model" in the top right corner.
Enter the model details
Keep "Create Manually" selected and fill in the model details:
Name:GLM-5.3 via OpenCode Go(or your preferred name)Model ID:glm-5.3for example (check OpenCode Go model list)Context Length: Enter the model's context window (e.g., 1000000 for glm-5.3)
Set up authentication
In the "Authentication" tab, set the connection details:
API Type:OpenAI Chat Completions APIEndpoint URL:https://opencode.ai/zen/go/v1/chat/completionsAuthentication Type:API Key via HTTP HeaderHeader Key:AuthorizationHeader Value:Bearer <OPENCODE_API_KEY>
Add pricing (optional)
Open the "Pricing" tab and enter the model's input, output, and cache prices per 1M tokens so TypingMind can estimate your usage costs.
Check the capabilities
In the "Capabilities" tab, keep "Auto check capabilities on save" on so TypingMind detects supported features like plugins, image input, and thinking, or enable them manually.
Route requests via TypingMind Cloud
OpenCode Go doesn't accept requests directly from the browser. Open the "Request Options" tab and turn on "Route requests via TypingMind Cloud".
Test and save
Click "Test & Save" to verify the connection and add the model.
