ChatGPT Work Is Two Different Products Wearing One Name
ChatGPT Work, announced by OpenAI on July 9th, is actually two separate products bundled under one name: a cloud version reachable at chatgpt.com and a separate local variant.
What it is
ChatGPT Work is OpenAI's product for professional and team use of ChatGPT, announced in July and iterated on heavily since. Simon Willison spent time figuring out what it actually does because the product itself does not make that obvious.
What it does
Willison found ChatGPT Work splits into two distinct experiences: a cloud-based version accessible through chatgpt.com and mobile apps (which he calls Work Cloud), and a separate mode with different capabilities and constraints, all sharing the same branding.
Why it matters
If even a dedicated tech writer needs a blog post to explain what a shipped product does, that's a signal the product surface is more confusing than the marketing suggests, worth knowing before you recommend it to a team.
How to use it
