Retired: Gemini 3.1 Flash Lite Preview `google/gemini-3.1-flash-lite-preview` has been retired: Google removed the underlying preview model from its API. Requests for this id now return a `model not supported` error. Use `google/gemini-3.1-flash-lite` instead — the stable successor at the same pricing. See the [Agent API Models reference](https://docs.perplexity.ai/docs/agent-api/models.md).
