OpenCode

Prepare API

Before configuration, make sure you have the following information:

API Key

A string of your created API Key.

Base URL

Address: https://api.jalapeno-cloud.ai/v1

Important: Must include the trailing /v1

Model Name

Copy the full model name from the Model Marketplace, e.g., DeepSeek-V4-Pro

Install OpenCode

Download and install through OpenCode official channels. OpenCode

Linux / macOS / WSL2

curl -fsSL https://opencode.ai/install | bash

Or install via npm:

npm install -g opencode-ai

Windows

OpenCode recommends WSL2 for the best experience. Install inside WSL2 using the Linux command above.

For native Windows, install via Chocolatey or Scoop:

choco install opencode
# or
scoop install opencode

Or install via npm:

npm install -g opencode-ai

Connect OpenCode

OpenCode routes requests through a custom provider defined in ~/.config/opencode/opencode.json.

Edit Configuration File

Create or edit ~/.config/opencode/opencode.json:

{
  "$schema": "https://opencode.ai/config.json",
  "model": "jalapeno/GLM-5.1",
  "provider": {
    "jalapeno": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "Jalapeno Cloud",
      "options": {
        "baseURL": "https://api.jalapeno-cloud.ai/v1",
        "apiKey": "{env:JALAPENO_API_KEY}"
      },
      "models": {
        "GLM-5.1": {
          "name": "GLM-5.1"
        },
        "DeepSeek-V4-Pro": {
          "name": "DeepSeek-V4-Pro"
        },
        "MiniMax-M2.7": {
          "name": "MiniMax-M2.7"
        }
      }
    }
  }
}

Field Description

Field	Description
model	Default model in provider/model format (e.g., jalapeno/GLM-5.1)
npm	AI SDK package; use @ai-sdk/openai-compatible for /v1/chat/completions
name	Display name for the provider
options.baseURL	API endpoint, must include trailing /v1
options.apiKey	API key; use {env:VAR_NAME} to read from an environment variable
models	Model IDs available from the Model Marketplace

Note: The top-level model field is required. Model IDs under models must match names from the Model Marketplace.

Set API Key

Export your API key before running OpenCode:

export JALAPENO_API_KEY="your-api-key"

Add the export line to your shell profile (e.g. ~/.bashrc or ~/.zshrc) to persist it across sessions.

Alternatively, run opencode providers login, choose Other, enter provider ID jalapeno, and paste your API key.

Switch Model

Change the top-level model field, or pass -m on the command line:

"model": "jalapeno/DeepSeek-V4-Pro"

Verify Connection

With JALAPENO_API_KEY exported, run:

opencode run -m jalapeno/GLM-5.1 "Reply with exactly one word: hello"

A successful run returns pong.

Use Model

Start the interactive TUI in your project directory:

opencode

Use /models in the TUI to switch models.
