Inception Labs is shutting down the Mercury API, the hosted service behind its Mercury diffusion-based language models, according to an email that a Hacker News user reported receiving from [email protected] and reproduced in full. At the time of the post, the company had not published a blog announcement, though the poster expected one to follow.
In the email, signed by "The Inception Team," the company says the Mercury API will remain fully available through 28.12.2026. After that date, customers will lose access to the service and to any data they submitted to the platform, and the company urges users to retrieve whatever they need beforehand. The message invites recipients to reply to the email with questions or for help with the transition, and thanks customers, saying their feedback and ideas shaped the platform.
A shorter version of the announcement also appeared on the company's Discord server in a message attributed to Yannis Miraoui. It states that API access to all Mercury models ends on 28.12.2026 and adds one detail not present in the email: Mercury models would no longer be available via OpenRouter from 08.11.2026.
