What changed on the XERJ Platform, newest first.

November 2026: preview #

The XERJ Platform opens as a free preview.

• XERJ Reader (xerj-reader-1): answers a question from a document with the exact span and its character offsets, Yes or No, or “not in this document”, always with a confidence.
• Endpoints: POST /v1/answers, POST /v1/extract, POST /v1/convert, GET /v1/models, GET /v1/usage.
• SDKs 0.1.0 for Python and JavaScript, installed from platform.xerj.ai until they are on PyPI and npm.
• Price: $0.01 per 1M input tokens, output free. The preview plan is free, with 60 requests per minute and 2,000,000 input tokens per UTC day.
• Sign-in with GitHub or Hugging Face through hub.xerj.org.
• Access by invitation during the preview: request access with your company, work email and role. Approved accounts get an activation link by email.
• Examples at /playground: real answers on invoices, contracts, insurance claims, logs and email, computed in advance. Active accounts get the live playground on the same page.
• Coming soon: XERJ Extract (xerj-extract-1), typed field programs with evidence.
