:magnifying_glass_tilted_left: Problem Statement

Currently, opening a long thread in Perplexity fetches and renders the entire chat history at once. This causes massive UI lag and eventually kills or freezes the browser tab due to memory overload.

:light_bulb: Proposed Solution

The proposed feature is to implement lazy loading for the chat window. Additionally, when opening an existing chat, it should start at the very bottom (showing the latest message first) and load older messages bottom-to-top as you scroll up, similar to standard chat apps.

Hey — this forum is specifically for the Perplexity API (Sonar models, Search API, Agent API, SDKs, billing/credits). For issues with the Perplexity consumer product (web app, mobile, Spaces, Library), the best route is the in-app help or support at support.perplexity.ai.

Closing this thread, but feel free to open a new one if you have an API-related question.
