Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited language model support beyond major providers

   The app primarily supports ChatGPT, Anthropic Claude, and Google Gemini, which may not cover niche or specialized LLMs.

2. 02

   Complex setup for customization due to open-source nature

   Customizing the app requires significant Android development knowledge in Java/Kotlin, making it challenging for developers unfamiliar with these languages.

3. 03

   Performance issues on lower-end devices

   Running multiple large language models simultaneously can be resource-intensive and may lead to lag or crashes on less powerful Android devices.

4. 04

   Dependence on third-party APIs for LLMs, leading to potential reliability issues

   The app relies on external services for language models which can introduce latency and availability concerns if those services experience downtime or rate limiting.

What it does well

• Supports multiple LLMs in one app
