perplexityai agent not working well

[xuyangyuio]

The perplexityai agent can't search the internet.

It uses only the pre-trained info:

It can help with local code:

It can not search the internet:

I dont think this is plugin issue but I can double check if its using correct endpoint. Have you tried using empty system prompt? Because otherwise the perplexity agent lives elsewhere and has its implementation elsewhere

[xuyangyuio]

Thanks for the quick reply. I tried with empty system prompt, then, instead of "I can't assist with that", perplexityai still reponded with something like "I currently don't have information about GitHub features introduced in 2025, as my knowledge cutoff is October 2023. To stay updated on GitHub's latest features, you can check their official blog or release notes:"

Can it be authentication problem? I am asking because even if I revoke the perplexityai authorization in GitHub, perplexityai agent still "works", i.e. give response related to local code, but has a knowledge cutoff of 2023. Comparing to vscode which will ask me to authorize if I revoke the perplexityai app authorization in GitHub.

There is delay between you unregister perplexity and before it actually stops working so that part doesnt matter. I just tested perplexity and im definitely getting at least correct response, e.g

[CopilotChat] [DEBUG 15:43:48] /home/deathbeam/.config/nvim/pack/bundle/start/CopilotChat.nvim/lua/CopilotChat/client.lua:574: Response line: {"choices":null,"copilot_references":[{"type":"github.agent","data":{"type":"github.agent","id":603,"login":"perplexityai","avatarURL":"https://avatars.githubusercontent.com/in/1026421?s=60\u0026u=dc3f91fbb805eab67f66223e98477f2a63961d82\u0026v=4","url":"https://github.com/marketplace/perplexityai"},"id":"603","is_implicit":false,"metadata":{"display_name":"perplexityai","display_icon":"https://avatars.githubusercontent.com/in/1026421?s=60\u0026u=dc3f91fbb805eab67f66223e98477f2a63961d82\u0026v=4","display_url":"https://github.com/marketplace/perplexityai"}}],"id":null}

can you try enabling debug logs and check if you see something similar? e.g in copilot_references there should be perplexity mentioned

After updating the plugin, I do get the similar logs.
