OpenAI May Build an AI-Agent Phone to Replace Apps

Analyst Ming-Chi Kuo reports OpenAI is developing a smartphone with MediaTek, Qualcomm, and Luxshare, using AI agents instead of traditional apps.

What happened

Ming-Chi Kuo, a respected hardware analyst known for accurate Apple leaks, published a note claiming OpenAI is co-developing a smartphone with MediaTek and Qualcomm for chips, and Luxshare for co-design and manufacturing. The device would replace apps with AI agents that have unrestricted system access — bypassing Apple and Google's app store controls. Mass production is expected to start in 2028, with the device first appearing in Q-something 2027. OpenAI's Chief Global Affairs Officer previously confirmed a first hardware product announcement in H2 2026, pointing to earbuds.

Why it matters to you

If OpenAI ships a phone where AI agents replace apps, the entire mobile app architecture becomes a legacy pattern. Developers who've built on iOS/Android APIs are building for a platform that OpenAI is actively trying to obsolete. The on-device + cloud hybrid model Kuo describes also signals a shift in how AI inference is distributed — small models handling local context, cloud models handling heavy tasks — which changes how you architect latency-sensitive AI features.

What to do about it

This week, prototype one user flow in your app as a pure agent interaction — no UI buttons, no screens — using the OpenAI Assistants API with function calling. Measure if the output is actually usable. If it is, you have a head start on the agent-native paradigm.

A structured function call to set_reminder with correct parameters, plus a natural language confirmation — a working proof-of-concept of agent-as-interface

Suggested exercise · not independently tested. Access requirements and costs may vary.

1
Go to platform.openai.com and open the Assistants playground
2
Create an assistant with this system prompt: 'You are an AI agent that completes tasks for a user without a traditional app UI. The user will describe what they want done. You have access to functions: search_web, send_message, set_reminder. Respond with a function call and a plain-language confirmation.' Then send: 'Remind me to follow up with my investor on Friday at 9am'
3
Observe whether the agent correctly chains function calls and handles the task without any UI scaffolding
