What do people actually use offline LLMs on iPhone for?

A long discussion about mobile offline LLMs on iPhone asks what people actually use them for.
The poster says they’ve spent the past year testing open-source MLX and GGUF models on iPhone hardware and found a few practical patterns:
- Apple Foundation models are limited, but useful for tool calling, fast summarization, and classification before handing work to stronger models.
- Models from 0.5B to 8B can work on higher-end devices.
- They’ve used them for:
- web search and URL scraping
- summarization
- research
- analyzing local photos, videos, and documents
- basic on-the-go coding help
- With continuous compaction, they claim to keep chats effectively unbounded despite 8k–16k token context limits.
- They also suggest private, offline personal chat as another promising use case.
The main question is whether mobile is still underexplored compared with laptops and desktops.
