Modal launches Spindle open-source training server

Modal has launched Spindle, an open-source training server designed to be compatible with the Tinker API. Spindle aims to address the cost and customization limitations of per-token pricing models by allowing users to run their own training loops on Modal's infrastructure. This new offering complements Modal's existing post-training tools, Modal Dojo and raw primitives, providing a middle ground for users who want control over their training process without managing the underlying hardware. AI

IMPACT Provides a more cost-effective and customizable option for AI model training, potentially accelerating experimentation for teams.
