Vercel has made Glyph Cluster available through AI Gateway to teams on Pro and Enterprise plans with purchased Gateway credits. The reasoning model is free during its stealth period and supports coding, long-context analysis and multi-step tasks such as planning and quantitative reasoning.

Teams can call it through the AI SDK or compatible Chat Completions and Responses APIs. It streams responses and can call functions that developers define to connect it to their tools.

The model accepts text only, lacks structured outputs and does not support Zero Data Retention. Prompts and responses may be used for training and model improvement.
