The provider pricing page that our daily tracker reads for this model.
Server-rendered WordPress HTML (wp-json/wp/v2/pages/23501: status publish, modified 2026-05-06). The 'Foundation Models' section has one card per Jamba model: an h3 name line, an optional description line, then a footer that the <br> splits into '$X / 1M input tokens' and '$Y / 1M output tokens' lines. These are the AI21 platform pay-as-you-go prices: the Pay As You Go plan says 'See usage pricing for Foundation Models', and the Custom Plan only promises volume discounts without numbers. No cached-input or batch price is published (docs jamba-batch-api.md has no price). Alternatives checked on 2026-10-08: /pricing.md is 404, accept: text/markdown still returns HTML, www.ai21.com/llms.txt has no pricing entry, docs.ai21.com/docs/usage-cost.md defers to this page for platform prices, and the wp-json record only wraps the same rendered HTML (acf is empty). The page carries robots noindex and is not in the site navigation; if it disappears, check docs usage-cost.md for its replacement.
