It is free to use during the stealth period.\n\nGlyph 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.\n\nFor coding, Glyph Cluster can review code, explain failures, debug issues, propose changes, and reason through implementation options. It supports [function calling](https://vercel.com/docs/ai-gateway/sdks-and-apis/responses/tool-calling), so agents can connect its reasoning to your own tools and systems, and it streams responses as they are generated.\n\nGlyph 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.\n\nZDR is not available for this model, and prompts and responses sent through it may be used for training and model improvement.\n\nCall it through the [AI SDK](https://vercel.com/docs/ai-gateway/sdks-and-apis/ai-sdk) or the OpenAI-compatible [Chat Completions](https://vercel.com/docs/ai-gateway/sdks-and-apis/openai-chat-completions) and [Responses](https://vercel.com/docs/ai-gateway/sdks-and-apis/responses) APIs, or select it in a [coding agent](https://vercel.com/docs/ai-gateway/coding-agents) connected to AI Gateway.\n\nUse `stealth/glyph-cluster` as the model name:\n\nTo use it in Claude Code, Codex, Cursor, and more, install the latest Vercel CLI and run setup:\n\nThen select `stealth/glyph-cluster` in the agent. See the [coding agents guide](https://vercel.com/docs/ai-gateway/coding-agents) for details.\n\nTry Glyph Cluster in the [model playground](https://vercel.com/ai-gateway/models/glyph-cluster).\n\nAI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-provider uptime. It includes built-in [custom reporting](https://vercel.com/changelog/custom-reporting-ai-gateway), [Zero Data Retention support](https://vercel.com/blog/zdr-on-ai-gateway), [budgets for API keys](https://vercel.com/docs/ai-gateway/authentication-and-byok/api-keys), [routing rules](https://vercel.com/docs/ai-gateway/models-and-providers/routing-rules), and more.\n\nAI Gateway reflects provider pricing with no markup and does not charge a platform fee on inference, including on [Bring Your Own Key](https://vercel.com/docs/ai-gateway/authentication-and-byok/byok) (BYOK) requests.\n\nYou can view [all language models](https://vercel.com/ai-gateway/models?type=text) available on AI Gateway.", "url": "https://wpnews.pro/news/glyph-cluster-is-now-available-in-stealth-for-free-on-ai-gateway", "canonical_source": "https://vercel.com/changelog/glyph-cluster-is-now-available-in-stealth-for-free-on-ai-gateway", "published_at": "2026-10-07 00:00:00+00:00", "updated_at": "2026-10-07 18:16:19.616094+00:00", "lang": "en", "topics": ["large-language-models", "ai-products", "ai-tools", "ai-agents", "developer-tools"], "entities": ["Vercel", "AI Gateway", "Glyph Cluster", "AI SDK", "Claude Code", "Codex", "Cursor", "Vercel CLI"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/glyph-cluster-is-now-available-in-stealth-for-free-on-ai-gateway", "markdown": "https://wpnews.pro/news/glyph-cluster-is-now-available-in-stealth-for-free-on-ai-gateway.md", "text": "https://wpnews.pro/news/glyph-cluster-is-now-available-in-stealth-for-free-on-ai-gateway.txt", "jsonld": "https://wpnews.pro/news/glyph-cluster-is-now-available-in-stealth-for-free-on-ai-gateway.jsonld"}}
