description: Manage the custom Arka-AI (arka-ai.ru) LLM provider in opencode config. Use when the user needs to add, refresh, or fix the arka-ai.ru provider, sync its model catalog, change the Arka-AI default model, or when arka models are missing from /models.

# Arka-AI provider
|
|
|
|
arka-ai.ru is **not** in models.dev, so opencode ships no built-in config for it.
|
|
It is wired up locally with a plugin + a static `provider` block in
|
|
`~/.config/opencode/opencode.json`.
|
|
|
|
## How it works
|
|
|
|
- Plugin: `~/.config/opencode/plugins/arka-ai.ts`
|
|
- On startup it loads the published chat catalog
|
|
`https://git.arka-ai.ru/arka/public/raw/branch/main/catalog.json`
|
|
(no API key; refreshed daily at 05:00 Europe/Moscow).
|
|
- If that fetch fails, it falls back to `https://api.arka-ai.ru/v1/models`
|
|
and filters out non-chat models (TTS/ASR/image/video/OCR/embedding/reranker/…)
|
|
via a heuristic regex so the `/models` picker stays clean.
|
|
- Caches the result at `~/.cache/opencode/arka-ai-models.json` (TTL 24h).
|
|
- Injects the provider into config via the `config` hook, layered over the
|
|
static block in `opencode.json`.
|
|
- Static block (`opencode.json` → `provider["Arka-AI"]`) holds
|
|
`name`, `api`, `env`, and a small fallback `models` map that is used when the
|
|
catalog is unreachable.
|
|
- Inference still uses `ARKA_API_KEY` against `https://api.arka-ai.ru/v1`.
|
|
|
|
## Refresh the model list
|
|
|
|
Catalog ~216 raw models / ~116 chat; the public snapshot updates at 05:00
|
|
Europe/Moscow. Changes land in opencode only after cache expiry + restart
|
|
(config is not hot-reloaded).
|
|
|
|
1. `rm -f ~/.cache/opencode/arka-ai-models.json`
|
|
2. Restart opencode (or run `opencode` again) — the plugin re-fetches on the
|
|
next cold start.
|
|
|
|
Optionally inspect the live API (no key required for listing):
|
|
|
|
```bash
|
|
curl -sS https://api.arka-ai.ru/v1/models | python3 -m json.tool
|
|
curl -sS https://git.arka-ai.ru/arka/public/raw/branch/main/catalog.json | python3 -m json.tool
|
|
```
|
|
|
|
## Change default model
|
|
|
|
Edit `opencode.json` → `"model": "Arka-AI/<model-id>"`. Use the IDs exactly as
|
|
returned by the catalog (e.g. `Arka-AI/DeepSeek-V4-Pro`,
|
|
`Arka-AI/qwen3.8-max`, `Arka-AI/kimi-k3`).
|
|
|
|
## Adjust filtering
|
|
|
|
Edit `NON_CHAT` (regex) or `FORCED_MODELS` in the plugin file **and** the same
|
|
lists in `scripts/sync-catalog.py` in `arka/public`, then re-run the installer
|
|
and restart. `FORCED_MODELS` keeps must-have chat models even if the heuristic
|
|
would drop them.
