- **Per-model routing**: Opus / Sonnet / Haiku requests are resolved to their model-specific backend and provider, with the default `MODEL` as fallback
- **Request optimization**: 5 categories of trivial requests (quota probes, title generation, prefix detection, suggestions, filepath extraction) are intercepted and responded to instantly without using API quota
- **Format translation**: real requests are translated from Anthropic format to the provider's OpenAI-compatible format and streamed back

Switch providers by changing `MODEL` in `.env`. Use the prefix format `provider/model/name`. Invalid prefix causes an error.
Models use a prefix format: `provider_prefix/model/name`. An invalid prefix causes an error.

## Discord Bot
Control Claude Code remotely from Discord. Send tasks, watch live progress, and manage multiple concurrent sessions. Telegram is also supported.
Control Claude Code remotely from Discord (or Telegram). Send tasks, watch live progress, and manage multiple concurrent sessions.
**Capabilities:**
- Tree-based message threading: reply to a message to fork the conversation
- Session persistence across server restarts
- Live streaming of thinking tokens, tool calls, and results
- Unlimited concurrent Claude CLI sessions (provider concurrency controlled by `PROVIDER_MAX_CONCURRENCY`)
- **Voice notes**: send voice messages; they are transcribed and processed like regular prompts (see [Voice Notes](#voice-notes))
- Commands: `/stop` (cancel tasks; reply to a message to stop only that task), `/clear` (standalone: reset all sessions; reply to a message to clear that branch downwards), `/stats`
