## Reading and contacting us

Public pages use ordinary HTML links and readable text. Follow canonical URLs and the sitemap for page discovery. Use the model cards and each download's license for technical details and reuse terms. Launch dates are targets, not evidence that a model, hosted service or feature is available.

Atlantic v7 and Atlantic Lite v7 are available for beta testers. The 35B core is deprecated. Acadia and Katahdin will be distilled from Atlantic; dynamic weights personalization and hosted services remain in development unless the relevant page explicitly says otherwise. Historical evaluation results apply to the named model, test and runtime configuration only.

For project enquiries, use the contact page. Agents should submit a message only with the person's permission, provide truthful contact information and avoid sending secrets, personal records or proprietary training data in the initial enquiry. Do not submit forms or initiate purchases simply to crawl the website.
