OpenAI Targets Siri: ChatGPT’s Bold Move Into the iPhone Ecosystem
Unsealed strategy document reveals vision for a super-assistant challenging Apple’s AI dominance
ChatGPT’s next leap: the always-on super-assistant
A newly unsealed internal document titled “ChatGPT: H1 2025 Strategy”, obtained through the DOJ’s antitrust case against Google and reported by The Verge, unveils OpenAI’s aggressive roadmap to evolve ChatGPT into a ubiquitous AI assistant—one that directly challenges Apple’s Siri across every user interface.
- Described as a “super-assistant”, ChatGPT aims to become deeply personal, omnipresent, and highly capable, bridging the gap between casual tasks and expert-level support.
- The assistant will be accessible across platforms—phones, emails, apps, websites, and even third-party tools like Siri.
The T-shaped assistant model
The document outlines a T-shaped capabilities model for the assistant:
- The horizontal skills will cover daily, tedious tasks:
- Answering questions
- Managing to-dos and calendars
- Sending emails
- Planning vacations and contacting services
- The vertical depth will tackle high-skill tasks, especially in domains like coding, with more areas teased but redacted.
This T-shaped approach reflects OpenAI’s recent product evolution, including memory features, Operator, and multimodal interactions, all of which demonstrate a shift toward continuous, proactive AI rather than reactive chatbot-style queries.
OpenAI’s challenge to Apple’s walled garden
The document also contains a clear critique of platform gatekeeping by dominant tech firms like Apple, Google, and Microsoft. OpenAI argues that:
- Users should have the freedom to select their default AI assistant on any device or operating system.
- Tech giants must offer alternatives and make core services, like search indexes, accessible to other AI tools such as ChatGPT.
This approach forms the basis of a regulatory pitch aligned with growing global concerns around antitrust and competition in AI and search technologies.
Siri integration isn’t enough for OpenAI
Despite ChatGPT already serving as Siri’s fallback assistant in many instances, OpenAI sees this as a stepping stone, not a final destination. The document asserts that:
- “Real choice drives competition and benefits everyone.”
- ChatGPT should not be confined by platform limitations, and users should be able to set it as the default assistant if they choose.
This signals a direct challenge to Apple’s closed ecosystem, which has long restricted third-party system-level integrations.
Apple’s AI roadmap in flux
In contrast, Apple’s own AI development appears scattered and reactive:
- Siri’s leadership has shifted under Mike Rockwell, now reporting to the Vision Pro team.
- Robby Walker, former Siri lead, now heads an internal project called “Knowledge”, seen as Apple’s response to ChatGPT.
- However, reports from Bloomberg’s Mark Gurman suggest the effort is facing similar structural issues that stalled Siri’s evolution in the past.
Strategic implications ahead of WWDC
With Apple’s WWDC just around the corner, the pressure is on. OpenAI’s plans not only reveal a clear technological trajectory but also position it as a pro-consumer voice in the broader AI and platform competition narrative.
- Observers expect WWDC announcements to be defined as much by what Apple omits as by what it reveals, particularly regarding AI openness and default assistant choices.
OpenAI’s strategy to embed ChatGPT deeply into the digital fabric of everyday life signals a tectonic shift in how users interact with AI. As Apple’s internal struggles continue and regulatory scrutiny builds, the battle for the AI layer on your iPhone is just beginning.
