# fetch_models_for_opencode

A small Go tool that fetches the model list from an OpenAI-compatible endpoint
(`GET <baseurl>/models`) and generates an `opencode.jsonc` config file for
[OpenCode](https://opencode.ai).

OpenCode only allows adding models manually via `opencode.jsonc` – there is no
way to import them automatically. This is tedious when your provider offers many
models.

**Example:** I run this tool against [OmniRoute](https://omniroute.online), a
local AI gateway that exposes hundreds of models and combo models through a
single OpenAI-compatible endpoint – exactly the models I want to use in OpenCode.
Instead of writing every entry by hand, this tool generates the complete provider
config in one go.

## How it works

- Fetches `/models` from the given base URL
- Creates a provider entry (`@ai-sdk/openai-compatible`) with all models
- Context/output limits are read from model metadata (fallbacks: 131072 / 8192)

## Usage

```
go run . --provider Myprovider --baseurl http://localhost:8080/v1
```
