1. 1
   Install Termux

   Get Termux from F-Droid or its GitHub releases page. The Play Store version is no longer maintained and does not work.

2. 2
   Pick a mirror and update

   Open Termux and run the first command. Choose Mirror group and a region near you, then update the packages.

   bash

   termux-change-repo
   pkg update && pkg upgrade

3. 3
   Install the requirements

   This installs Git and Node.js. On an older 32-bit phone, also run `pkg install esbuild` if the start fails with Unsupported platform.

   bash

   pkg install git nodejs-lts nano

Recommended models

Free models that work here. Paste any model id into the client.

Gotchas

• !Paste the base URL ending in `/v1` only. SillyTavern appends `/chat/completions` itself; adding it returns a 400 error.
• !An empty model dropdown means the connection failed. Re-check the base URL, then enable Bypass API status check.
• !A 401 means the key is expired or mistyped. Generate a fresh key in your Lumen dashboard and paste it without leading or trailing spaces.
• !If streaming cuts off mid-sentence, disable Streaming to confirm the cause, then re-enable it. Corporate proxies that strip the `data:` prefix also break it.
