Apple Built Siri So You Can Swap It for Claude or ChatGPT
Apple's Siri AI Can Be Swapped Out for Claude, ChatGPT, Code Shows
Code sleuth pdfu found private iOS 27 and macOS Golden Gate frameworks showing Apple designed Siri for deep third-party AI integration. One protocol, Model Delegation, lets Claude act as a Siri extension, handing tasks back to Siri for system actions. A second protocol, an inference provider in Model Manager Services, can replace Apple's server-side Siri model entirely with GPT-5.6, which receives Siri's planner prompt and tool definitions. The EU's Digital Markets Act may have shaped this approach.
An inference provider in "Model Manager Services" apparently allows Apple's own server-side Siri model to be completely replaced by another model, such as GPT-5.6.

Siri was the first widely available AI bot but they forgot to open it to developers. The ecosystem would have grown a million fold in all these years

Now that's an agent I'd use. Can we start with Siri for the terminal?

It’d be short sighted to not have a wrapper around which AI to use, even without implementation for them. Like, having an abstract parent class with a Siri implementation of it would be baseline good software engineering.

And you can also sideload apps (only in the EU), change you default navigation app from apple maps (only in the EU), and use more features of the NFC reader (only in the EU).
The code for all of those things is there, but not enabled if for most iOS users. There's a non-zero chance this code is there for Apple to try and convince the EU to let them release a Siri AI, and then just like sideloading have some impossible-to-actually-use alternative path to make the DMA happy.

I pray for the possibility of not only choosing the provider, but being able to choose the thinking level.
I've been using the new siri, and it seems more or less stuck in instant-answer mode, which gives really terrible answers with any provider.
I wish more people were talking about this, but if you can't crank up the models to extended thinking, the technology is more or less stuck at 2004 levels of usefulness.

My favorite Siri behavior is telling it, on my phone, to turn on a focus state only for it to transfer the request to a nearby HomePod that tells me it can't help with that. I hope the new changes to it are an improvement, but the bar is currently buried in the dirt.

This is a very clever platform play. If you make Siri / your mac the central access point for all AI related workflows and make models interchangeable, then Apple has a huge weapon in the AI race.

That’s actually a good solution. Create a platform where app actions can be invoked with a permission model by any AI model.
Maybe apple can even have something similar to MCPs for tool invocations of apps and publish it so all models can actually be trained to use that framework

I would pay a good chunk of money if Apple released a local AI hub to coordinate all AI usage locally (including photo indexing).
