# opencode-provider-switch (`ops`)
|
|
|
|
A tiny local proxy for [OpenCode](https://opencode.ai) that gives you **one
|
|
stable model alias** routed to **multiple upstream providers** with
|
|
**deterministic failover**.
|
|
|
|
- Expose one custom provider `ops` to OpenCode.
|
|
- Configure logical aliases (`ops/gpt-5.4`, etc.).
|
|
- Each alias has an ordered list of upstream `provider/model` targets.
|
|
- When the primary upstream returns `5xx`/`429`/connect error *before* any
|
|
stream bytes are flushed, `ops` transparently retries the next target.
|
|
- Once a stream has started, the upstream is locked for the rest of that
|
|
request — no mid-stream splicing.
|
|
|
|
Protocol: OpenAI Responses (`POST /v1/responses`) only. Streaming supported.
|
|
|
|
## Install
|
|
|
|
```bash
|
|
go build -o ops ./cmd/ops
|
|
```
|
|
|
|
## Quick start
|
|
|
|
```bash
|
|
# 1. add upstream providers
|
|
ops provider add --id su8 --base-url https://cn2.su8.codes/v1 --api-key sk-...
|
|
ops provider add --id codex --base-url https://api-vip.codex-for.me/v1 --api-key sk-...
|
|
|
|
# 2. create alias and bind targets in priority order
|
|
ops alias add --name gpt-5.4
|
|
ops alias bind --alias gpt-5.4 --provider su8 --model gpt-5.4
|
|
ops alias bind --alias gpt-5.4 --provider codex --model GPT-5.4
|
|
|
|
# 3. push alias exposure into OpenCode global config
|
|
ops opencode sync
|
|
|
|
# 4. run the proxy
|
|
ops serve
|
|
```
|
|
|
|
Inside OpenCode you can now pick `ops/gpt-5.4`.
|
|
|
|
### Import providers from an existing OpenCode config
|
|
|
|
```bash
|
|
ops provider import-opencode # reads global OpenCode config
|
|
ops provider import-opencode --from ./examples/opencode.jsonc
|
|
```
|
|
|
|
Only `@ai-sdk/openai` custom providers with a `baseURL` and `apiKey` are
|
|
imported. Everything else is out of MVP scope.
|
|
|
|
### Doctor (static)
|
|
|
|
```bash
|
|
ops doctor
|
|
```
|
|
|
|
Runs structural checks only — never issues real upstream requests.
|
|
|
|
## CLI reference
|
|
|
|
- `ops serve` — run the proxy
|
|
- `ops doctor` — validate config
|
|
- `ops provider {add,list,remove,import-opencode}`
|
|
- `ops alias {add,list,bind,unbind,remove}`
|
|
- `ops opencode sync [--target FILE] [--set-model ALIAS] [--set-small-model ALIAS] [--dry-run]`
|
|
|
|
Global flag: `--config PATH` (default `$XDG_CONFIG_HOME/ops/config.json`).
|
|
|
|
## Debug headers
|
|
|
|
Every proxied response includes:
|
|
|
|
- `X-OPS-Alias`
|
|
- `X-OPS-Provider`
|
|
- `X-OPS-Remote-Model`
|
|
- `X-OPS-Attempt`
|
|
- `X-OPS-Failover-Count`
|
|
|
|
## Scope
|
|
|
|
Out of MVP: Anthropic native, multi-protocol routing, dashboard, billing,
|
|
latency-based routing, `/v1/models` discovery, full OpenCode config takeover.
