LiteLLM baut auf Python 3.14 nicht (orjson-Pin ohne cp314-Wheel). Stattdessen eingebauter Gateway in MC2: routers/gateway_proxy.py (/v1/chat/completions, /completions, /models) + services/router_logic.py (Komplexitaets-Routing fast<->heavy, Streaming-Passthrough). gateway.py/routing.py/connect.py auf builtin umgestellt (Endpunkt = MC :PORT/v1). Gleicher OpenAI-Vertrag, spaeter gegen LiteLLM austauschbar. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Eingebauter Routing-Gateway (OpenAI-kompatibel) — EIN Endpunkt für Hermes + IDEs.
|
|
|
|
`model: auto` → Komplexitäts-Routing fast↔heavy; jeder andere Name geht als
|
|
llama-swap-Alias durch (das lädt das Modell bei Bedarf). Streaming wird
|
|
durchgereicht. Ersetzt LiteLLM (das auf Python 3.14 nicht baut) — gleicher
|
|
Vertrag, später austauschbar.
