About LiteLLM Chat

LiteLLM Chat is a native Ubuntu Touch chat client for users who run or have access to an OpenAI-compatible LiteLLM proxy.

To be able to use this you need to run your own LiteLLM proxy either in the cloud or on your own hardware. See: https://docs.litellm.ai/docs/


Chat with your LiteLLM models
- Configure the LiteLLM base URL, bearer/API token, and optional Sticky Instruction in Settings.
- Model discovery uses the OpenAI-compatible /v1/models endpoint.
- Starting a new chat always asks which model to use.
- Each chat keeps its selected model for the life of that conversation.
- Messages use the OpenAI-compatible /v1/chat/completions endpoint.
- Multiple files can be attached through Ubuntu Touch Content Hub. Images are sent as image_url data and other documents as LiteLLM-compatible file content blocks when the selected model supports them.
- Attachment buttons in user and assistant messages export files through Content Hub. Supported assistant file URLs and file IDs are downloaded on demand.
- Sticky Instruction is captured when the first user message of a new conversation is sent and is inserted as a hidden system message before the visible chat context. It is not shown as a chat bubble. Existing conversations keep the instruction they started with.
- A waiting request does not lock navigation: you can return to Chats, start another chat, change settings, or use clipboard controls while it runs.
- Different chats can have requests pending at the same time; the current chat exposes a Cancel button while it is waiting.
- The message composer is raised above the Ubuntu Touch on-screen keyboard so entered text stays visible.
- Dedicated Copy buttons place any user or assistant message on the system clipboard.
- User and assistant message bubbles use small rounded corners.
- A dedicated Paste button inserts system clipboard text into the chat composer.
- The initial fallback list includes the chat-capable models supplied for litellm.powercraft.nl development.
- Embedding-only model IDs such as nomic-embed-text are not offered as chat models.

Local history
- Chat history is stored only in this application's private local data unless you export a backup.
- Existing chats can be reopened from the main screen.
- Every chat has a delete button.
- All local chats can also be deleted from the hamburger menu.

Backup and phone migration
- Backup and restore is available from the hamburger menu.
- Configuration, Sticky Instruction, and local chat history are exported/imported as UTF-8 JSON through Ubuntu Touch Content Hub.
- Credentials/secrets are excluded by default. Sticky Instruction is normal configuration and is included in backups.
- Include credentials/secrets is optional and off by default.
- If enabled, the LiteLLM API token is written to the JSON in plaintext. Protect or delete that file after migration.
- Restoring a backup without secrets clears the current token so it must be entered again on the restored phone.
- Attachment metadata is included in chat history, but binary attachment files are not embedded in JSON backups.

Persistent settings
- The LiteLLM URL, API token, Sticky Instruction, and theme setting are persisted immediately when changed.
- Saving does not depend on application shutdown, destructors, close events, or Component.onDestruction.
- Native settings writes use QSettings::setValue(...) followed immediately by QSettings::sync().
- Configuration is stored under the writable package-ID-specific application configuration directory for litellmchat.barrydegraaff.
- The API token remains available after the app is killed without a clean shutdown, provided the settings operation returned successfully.
- A restart-persistence regression test is included in the source and uses the production settings store.

Ubuntu Touch integration
- Native Qt/QML application for Ubuntu Touch 24.04 on arm64.
- Square logo without pre-rounded corners so Ubuntu Touch/OpenStore can apply the user's selected corner treatment.
- Purple gradient background with a simple white chat/robot symbol.
- Light mode and dark mode.
- Hamburger menu at the top right.
- About dialog includes version 0.1.6.
- AppArmor requests only networking and Content Hub exchange permissions needed for API access, attachments, and JSON backup/restore.

Privacy
- no advertising
- no analytics
- no tracking
- no telemetry
- no developer-operated intermediary service in the app
- chat/model network communication only with the LiteLLM URL configured by the user; choosing Download on an assistant-provided external file link connects to that file URL
- chat history stored in the application's private local data
- API token stored in the application's confined settings
- API token excluded from JSON backup unless explicitly enabled

Current 0.1.6 scope
- Text chat plus file/image attachments for models that support them through LiteLLM chat completions.
- Non-streaming chat completions.
- Up to 20 MB per attachment and 40 MB total attachments per message.
- JSON backups include attachment metadata but not attachment binary files.
- No embeddings UI yet.
- No tool/function calling UI yet.
- No agent-control UI beyond selecting an exposed model ID.
