Ratings and Reviews
Token problem
The idea is great but I can not use in a full posinilities. Why do I need tokens? Where I can exchange my text promt? What is this restrictions? On my iPhone it runs great, but why do I need some tokens to exchange text? Where I can get it???
Developer Response ,
Thank you for your feedback and questions! Let me clarify how this works:
1. Basic functionality is free - The core LLM features are available at no cost for basic usage.
2. About tokens and limits - "Tokens" represent the processing capacity needed for conversations. Each AI model and your device's RAM have natural limits on how long conversations can be. This isn't about payment - it's about technical constraints based on the specific model you're using and your device's capabilities.
3. How to use prompts - Simply enter your text prompt in the input box to start any conversation with the AI.
4. Customizing system prompts - If you want to modify how the AI behaves or responds, you can edit the system prompts by going to Settings > Chat Roles.
5. No token exchange needed - You don't need to "exchange" or purchase tokens for basic text conversations. The token limits mentioned are technical boundaries, not payment requirements.
Very slow and heating iPhone
I like app UI and variety of llm.
But AI chat is very slow and heating iPhone 16 plus.
App version 1.12.0
I hope next update improve the speed AI chat response .
Developer Response ,
Thank you for your feedback and sharing your concerns about performance.
This app runs the model directly on your device, which ensures that your data remains private and secure. However, this approach can be slower compared to models running on external servers due to the limitations of on-device processing.
To balance performance and speed, the default model has been chosen carefully. If you’re looking for faster response times, you can explore other available models like Qwen 2.5 (0.5B) or Llama 3.2 (1B), which may offer improved speed.
Your feedback is valuable, and we’re working to optimize the app further in future updates to enhance both speed and performance. Thank you for your support!
