Glyph Cluster now available in stealth on AI Gateway
Glyph Cluster, a reasoning model for coding and long-context analysis, is now available as a stealth model on Vercel's AI Gateway for Pro and Enterprise plan teams with purchased AI Gateway credits at no cost during the stealth period. The model supports function calling, streams responses, and can be accessed via AI SDK, OpenAI-compatible APIs, and coding agents.
is now available on as a stealth model for teams on with purchased AI Gateway credits. It is free to use during the stealth period.Glyph ClusterAI GatewayPro and Enterprise plans
Glyph Cluster is a reasoning model for coding and long-context analysis, and handles multi-step work such as planning, synthesis, quantitative reasoning, and comparing material across large inputs.
For coding, Glyph Cluster can review code, explain failures, debug issues, propose changes, and reason through implementation options. It supports , so agents can connect its reasoning to your own tools and systems, and it streams responses as they are generated.function calling
Glyph Cluster takes text input only, with no image or file input. Tool use is limited to function tools you define, and structured outputs are not supported.
ZDR is not available for this model, and prompts and responses sent through it may be used for training and model improvement.
