Claim
Meta has been the only company among the big five of Apple, Microsoft, Amazon, Google, and itself not to own a hardware platform or operating system.
Correction

This is incorrect because Meta already has both first-party hardware and its own operating system: Meta Quest headsets run on Meta Horizon OS.

Full reasoning

Meta has publicly described Meta Horizon OS as "the mixed reality operating system that powers our Meta Quest headsets." In the same announcement, Meta said it was "opening up the operating system that powers our Meta Quest devices" to third-party hardware makers.

That directly contradicts the claim that Meta does not own a hardware platform or operating system. By Meta's own description, it has:

  • hardware: Meta Quest headsets/devices
  • an operating system: Meta Horizon OS

So the statement is wrong as written.

  • Introducing Our Open Mixed Reality Ecosystem

    We're opening up the operating system that powers our Meta Quest devices to third-party hardware makers... This new hardware ecosystem will run on Meta Horizon OS, the mixed reality operating system that powers our Meta Quest headsets.

Claim
Llama 2: in June 2023, built by the GenAI product organization (as well as all subsequent Llama models)
Correction

The month is wrong: Meta announced Llama 2 on July 18, 2023, not in June 2023.

Full reasoning

Meta's own announcement for Llama 2 is dated July 18, 2023. The post says Llama 2 was released "in June 2023," but Meta's official release page states that the company announced Llama 2 on July 18, 2023.

Because this is a specific release-date claim, Meta's dated product announcement is the strongest source here.
