The legal battle between OpenAI and Apple took a dramatic turn when OpenAI released internal chat logs to counter accusations of systematic trade-secret theft. By publishing Apple’s own internal messages, OpenAI tries to shift the story from corporate espionage to Apple’s access-management failures.

The "Irregular" Communication Logs

At the center of the dispute is former Apple engineer Chang Liu, whom Apple says improperly accessed confidential information after moving to OpenAI. OpenAI, however, posted iMessage threads that show Apple employees actively asking Liu for technical help long after he left.

The logs record Liu’s last day at Apple as Jan. 22, 2026. Yet on Jan. 27, an Apple staffer wrote, "Of course, I could ask several folks, but you are the best. Even if you don't work here anymore." On Feb. 14, the same employee requested schematics, and by Mar. 5 Liu had been added to a group chat with several Apple staffers where he shared directions to internal folders and contacts. Liu later flagged the behavior as "highly irregular" and asked to be removed from the thread.

OpenAI says the logs expose a "residual access" problem, pointing to Apple’s poor internal access controls rather than OpenAI’s recruitment tactics as the source of the information flow.

Allegations of Systematic Theft and Hardware Ambitions

Apple’s complaint alleges that OpenAI encourages departing employees to copy files and specifications during their notice periods. The claim matters because more than 400 former Apple staff have joined OpenAI.

The timing matters for the AI industry. The lawsuit arrives as OpenAI pushes into hardware, partnering with the startup io Products, co-founded by former Apple design chief Jony Ive. Apple’s effort to protect its IP could create a massive bottleneck for OpenAI’s move from software to physical AI devices.

OpenAI also attacks Apple’s legal tactics. OpenAI says Apple’s counsel mixed up Asian last names in official letters, sending emails to the wrong recipients. OpenAI further disputes Apple’s claim that Apple’s lawyers spoke with OpenAI’s General Counsel by phone, insisting no such call occurred.

These blunders give OpenAI a tactical edge in the court of public opinion, but they do not answer the core legal question: whether OpenAI actively urged the theft of proprietary data.

Key Takeaways

  • Internal Access Failures: OpenAI alleges Apple employees bypassed security protocols by asking former staff for technical help and file locations via personal chat.
  • Strategic Stakes: The lawsuit threatens OpenAI’s hardware push, especially its partnership with Jony Ive’s io Products.
  • Broader Litigation: The chat logs highlight Apple’s management lapses, yet they do not yet refute the central claim that OpenAI encouraged trade-secret misappropriation.

Counter-argument from Apple

Apple says the messages do not prove a systemic breach. A few informal requests, Apple argues, do not constitute a policy that lets former staff access internal resources.

What to watch next

  • Court filings: Both sides will file motions on whether the chat logs are admissible and whether Apple’s internal policies meet industry standards for protecting trade secrets.

Takeaway: The public release of the iMessage threads forces the dispute into a new arena, where Apple’s own security lapses may become as contentious as the alleged theft. The outcome will likely shape the two companies’ legal battle and the broader rules governing talent moves in the AI era.
