Scale Spellbook

Scale Spellbook was Scale AI's tool for building and deploying large language model applications. The listing URL now redirects to the Scale GenAI Portfolio page, which is the vendor's current enterprise platform for building, deploying and improving AI agents that reason over a company's own data. The platform is organized around four stages. Connect Data ingests and structures enterprise data from sources such as Confluence, SharePoint and S3, with the data staying where it lives. Build and Execute hosts and orchestrates agents, including long running asynchronous workflows and multi agent coordination, with any model. Evaluate and Monitor applies automated and human feedback, evaluation scoring and full trace visibility to debug agents. Learn and Improve feeds human feedback and operational telemetry back in as training signal so agents improve with use. It is aimed at enterprise teams that want to run the whole agent lifecycle in one place. It works with models from OpenAI, Google, Meta and Mistral, supports fine tuning and open weight models, and deploys inside the customer's own cloud on AWS, Azure or GCP. Scale does not publish prices for the platform. Its pricing page directs visitors to book an introductory call, and the site asks prospects to talk to the team.
