OpenAI is offering $100 in ChatGPT credits to users of its paid plans (Go, Plus, Pro) who post about GPT-5.6 on X and register on a dedicated site, with the offer limited to the first 10,000 participants.
The campaign was announced by OpenAI executive Thibault Souteo and appears to be a competitive response to Anthropic, referencing a social media suggestion about cancellation incentives.
What happened
OpenAI is running a campaign where users of paid ChatGPT plans (Go, Plus, Pro) can post about their favorite aspects of GPT-5.6 or content created with it on X (formerly Twitter), then enter the post URL and their registered email on a dedicated site to claim $100 in ChatGPT credits; the offer is limited to the first 10,000 applicants.
Why it matters
The campaign directly targets Anthropic users — it was announced by OpenAI executive Thibault Soutou after quoting an X user's suggestion that Anthropic should offer free Codex access in exchange for screenshots of Claude cancellation screens — signaling OpenAI's awareness of direct competition for paid users.
What to watch
The dedicated campaign site was built using ChatGPT's new "Sites" feature, which allows publication of websites and lightweight applications; the choice to use this tool for the campaign suggests OpenAI is also promoting that feature alongside the credit offer.

The campaign reflects OpenAI's direct focus on retaining and engaging paid subscribers in an increasingly competitive AI market. The timing and framing—with Souteo explicitly quoting an X user's comparison to Anthropic's Claude and playfully invoking Anthropic's Codex product—suggest that OpenAI views user retention as a live battleground and is using promotional credits and social proof as a retention tactic. By encouraging users to publicly advocate for GPT-5.6 on X, OpenAI amplifies organic social signals that may influence fence-sitters or users of competing products.
The choice to build the campaign site using ChatGPT's new "Sites" feature—which enables no-code publication of websites and lightweight applications—serves a dual purpose: it lowers the friction for users to enter the campaign while simultaneously showcasing and validating the Sites product itself. This bundling of customer acquisition with product demonstration is a common growth pattern for feature launches and suggests OpenAI is strategically using high-visibility campaigns to drive adoption of new platform capabilities.
