Yes, it looks like Apple is going after everyone and anyone that has a web based LLM, ChatGPT, Poe, Claude, etc. via developer kits LLMKit that can work offline.
This will only work if their models (even their tiny or even medium / base models) equal (or are better than) GPT-3.5 / 4.
From there, Google will follow Apple in doing this offline / local LLM play with Gemini.
OpenAI's ChatGPT moat will certainly shrink a bit unless they release another powerful multimodal model.
