PPIO chat: is not valid for chat completion!

Error message

PPIO chat: ${this.model} is not valid for chat completion!

What it means

Model validation in PPIOLLM.getChatCompletion: the configured this.model is not in PPIO's list of chat-capable models, so a chat completion request would fail upstream; it is rejected before the API call.

Solutions

  1. Select a PPIO model valid for chat completion.
Defensive patterns

Strategy: validation

When it happens

Trigger: Thrown when the configured PPIO model is not a chat model.

Common situations: Model preference set to an invalid model.
