v5.4.1 **Fixes `claudebox-*` models silently answering from pibox-zai instead of Claude when called through the gateway.** - `claudebox-*` models failed through the gateway unless `CLAUDEBOX_API_TOKEN` was set in `.env`. The claudebox container falls back to `AIGATE_TOKEN` for its API token, but LiteLLM read `CLAUDEBOX_API_TOKEN` with no fallback, sent an empty key, and got `401`. The request then moved down the fallback chain to `pibox-zai-glm-5.3-flash` or `pibox-zai-glm-5.3` and still returned `200`, so the only sign was the `model` field in the response. LiteLLM now gets `CLAUDEBOX_API_TOKEN` and `PIBOX_ZAI_API_TOKEN` with the same `AIGATE_TOKEN` fallback the agent services use. `PIBOX_ZAI_API_TOKEN` had the same gap and only worked when set explicitly. - Recreate the `litellm` container to pick up the change.
