What is Spell ML?

Discover how Spell ML can enhance your workflow

Spell ML offered a cloud environment for reproducible machine learning experiments featuring hosted notebooks scalable GPU jobs datasets experiment tracking and collaborative workspaces aimed at research and applied ML teams. After the 2022 acquisition by Reddit the independent commercial service ceased onboarding and existing references persisted mainly in documentation and news coverage. This listing clarifies status and guides readers toward supported alternatives including major cloud notebooks managed training services and modern experiment tracking stacks with vendor commitments and security patches. Teams inheriting legacy Spell projects should export artifacts and migrate pipelines to maintained platforms that meet current compliance and cost expectations. Retaining this entry prevents confusion in audits and market research and helps students and practitioners understand the consolidation of MLOps platforms over the last cycle while pointing them to durable replacements aligned with today’s hardware availability model catalogs and governance options.
