NextChat

NextChat v2.16.1 connects to PopGo API through manual OpenAI-compatible configuration.

Before configuring

• This page uses placeholders only. Copy the real Key from PopGo API keys and the model from models and pricing.
• One-click setup is for software that is already installed and has registered its protocol handler. Allow the browser to open the external app when prompted.
• For manual setup, save one minimal Provider first. Enable streaming, tools, or multi-model routing only after the first request succeeds.

Official source and verification

This page was verified on 2026-07-14 against the official source for NextChat v2.16.1. Official source. Verification covers the official Releases and the current custom service workflow.

One-click setup

NextChat has no verified one-click import path. Enter the values manually in application settings and never pass a Key through a URL.

Manual setup

Enter the OpenAI-compatible service address, Key, and model in NextChat settings.

Field	Value
Provider type	OpenAI compatible
Base URL	https://api.popgo.site/v1
API Key	YOUR_API_KEY
Model	YOUR_MODEL

Success check

Save the settings, create a conversation, and send a short message with YOUR_MODEL.

Common errors and recovery

• If requests still use the default service, reopen settings and confirm that the custom address was applied.
• For a 401, paste YOUR_API_KEY again and remove surrounding whitespace.
• For a 404, verify the Base URL level and make sure the client is not appending /v1 twice.
