OpenCode

OpenCode

Connecting OpenCode to the gateway through an OpenAI-compatible provider in opencode.json.

OpenCode works through /v1/chat/completions in the OpenAI format.

Quick start

Put your key from the cabinet in the AISELLER_API_KEY environment variable — the config below reads it from there:

bash
export AISELLER_API_KEY="your-key"

Add the provider to ~/.config/opencode/opencode.json (or to opencode.json in a project root — then the setting applies only there):

json
{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "aiseller": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "ai-seller",
      "options": {
        "baseURL": "https://ai-seller.vibe-codes.ru/v1",
        "apiKey": "{env:AISELLER_API_KEY}"
      },
      "models": {
        "gpt-5.6-sol": { "name": "gpt-5.6-sol" }
      }
    }
  },
  "model": "aiseller/gpt-5.6-sol"
}

Run opencode. The aiseller provider name is arbitrary; the model is set as aiseller/<catalog ID>.

Choosing a model

List the IDs from the catalog you want to use under models — OpenCode shows them in the /models command. The model field sets the default.

How it works

  • The @ai-sdk/openai-compatible package sends requests to /v1/chat/completions with your key; usage shows up in the cabinet.
  • OpenCode's tools (reading and editing files, shell commands) are your own functions — the gateway passes them to the model as is.

Troubleshooting

SymptomCause and fix
The model is missing from /modelsIt is not listed in provider.aiseller.models — add its ID.
401 invalid_api_keyAISELLER_API_KEY is not set in this terminal, or the key is revoked.
404 model_not_foundThe model ID has a typo — check GET /v1/models.
