Applications expose Ampersand's two actions as caller-defined function tools — send_message delivers a contribution and pass leaves the conversation quiet until the next human message — and Ampersand accepts tool choice auto and none but rejects required and named tool choices. The model is callable through the AI SDK, the OpenAI-compatible Chat Completions API, or coding agents including Claude Code, Codex and Cursor via the latest Vercel CLI.", "body_md": "[Ampersand from Humans&](https://vercel.com/ai-gateway/models/ampersand-v0.1) is now available on AI Gateway for free through November 13, 2026.\n\nAmpersand is a language model built to take part in group conversations, such as a team chat, and to decide on each turn whether to speak or stay quiet. It is designed to understand individual and shared goals, help people work through disagreements, and recognize when a contribution would be useful. That can mean asking a clarifying question, sharing relevant context, or waiting while people respond to one another.\n\nYour application exposes these actions as caller-defined [function tools](https://vercel.com/docs/ai-gateway/inputs-and-tools/tool-use). `send_message` delivers a contribution, while `pass` leaves the conversation quiet until the next human message. Your application executes both tools and records their results. Leave tool choice at its default, since Ampersand accepts `auto` and `none` but rejects `required` and named tool choices.\n\nCall it through the [AI SDK](https://ai-sdk.dev/docs/ai-sdk-core/tools-and-tool-calling), the OpenAI-compatible [Chat Completions API](https://vercel.com/docs/ai-gateway/sdks-and-apis/openai-chat-completions), or a coding agent. Use `humansand/ampersand-v0.1` as the model name:\n\nThe first human message invites a contribution; the second asks Ampersand to wait. In a chat application, call the handler when a new human message arrives. Handling `pass` records the waiting action without posting a message or starting another model turn. For a deployed chat application, persist the response, history, and delivery receipts in durable storage. Retry uncertain delivery with the saved action and the same receipt, process messages sequentially per conversation, and check conversation access before posting.\n\nTo use it in Claude Code, Codex, Cursor, and more, install the latest Vercel CLI and run setup:\n\nThen select `humansand/ampersand-v0.1` in the agent. See the [coding agents guide](https://vercel.com/docs/ai-gateway/coding-agents) for details.\n\nTry Ampersand in the [model playground](https://vercel.com/ai-gateway/models/ampersand-v0.1).\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), [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/ampersand-from-humans-now-available-on-ai-gateway", "canonical_source": "https://vercel.com/changelog/humans-and-ampersand-now-available-on-ai-gateway", "published_at": "2026-11-06 00:00:00+00:00", "updated_at": "2026-11-06 21:20:28.923415+00:00", "lang": "en", "topics": ["large-language-models", "ai-agents", "ai-products", "developer-tools", "ai-tools"], "entities": ["Vercel", "AI Gateway", "Humans&", "Ampersand", "humansand/ampersand-v0.1", "AI SDK", "Chat Completions API", "Claude Code"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/ampersand-from-humans-now-available-on-ai-gateway", "markdown": "https://wpnews.pro/news/ampersand-from-humans-now-available-on-ai-gateway.md", "text": "https://wpnews.pro/news/ampersand-from-humans-now-available-on-ai-gateway.txt", "jsonld": "https://wpnews.pro/news/ampersand-from-humans-now-available-on-ai-gateway.jsonld"}}
