Ampersand v0.1

humansand/ampersand-v0.1 is humans&'s first model, Ampersand v0.1: a collaborator model for group chats that tracks what each person wants, flags conflicts, shares context, and asks questions. It is trained from GLM 5.3 (744B mixture-of-experts, about 40B active parameters) with a 1M-token context window, takes text in and text out, and supports reasoning effort and client-side function tools. The vendor reports the strongest teamwork scores in its tests and strong multi-agent coding results.

It is BYOK-only through Vercel AI Gateway. Add a Vercel AI Gateway key under Dashboard → BYOK; Vercel bills your own account and AnyRouter charges nothing. Ampersand lists at $1.00 per 1M input tokens and $5.20 per 1M output tokens at the owner, and Vercel offers it free through November 13.

tencent/hy4 is Tencent Hunyuan's Hy4 reasoning model, also reachable on apmix.ai's free tier: 1M-token context, text in and text out, reasoning that thinks before it answers. It is apmix's only free model — every new account gets 4M free tokens spendable on Hy4, with no daily limit or expiry. It is BYOK-only through apmix: add an apmix key under Dashboard → BYOK and AnyRouter charges nothing. The same key works on apmix's OpenAI-compatible and Anthropic-compatible endpoints. The free SKU ships as a route on tencent/hy4, not a separate model — filter to it with ?f=free or ?zdr=true on /models.

import { createAnyRouter } from "@anyr/ai-sdk-provider"
import { generateText } from "ai"

const anyrouter = createAnyRouter()
const { text } = await generateText({
  model: anyrouter("tencent/hy4"),
  prompt: "Say hello in one line.",
})
console.log(text)

The route is BYOK-only through Vercel AI Gateway. Add a Vercel key under Dashboard → BYOK; Vercel bills your own account and AnyRouter charges nothing. Ampersand lists at $1.00 per 1M input and $5.20 per 1M output at the owner, and Vercel is free through November 13.

import { createAnyRouter } from "@anyr/ai-sdk-provider"
import { generateText } from "ai"

const anyrouter = createAnyRouter()
const { text } = await generateText({
  model: anyrouter("humansand/ampersand-v0.1"),
  prompt: "Summarize what each teammate wants and flag any conflicts.",
})
console.log(text)

parallel/decisions-fast is Parallel's web-grounded Decisions model: send state and up to 100 typed questions (noul / choice / score) to POST /api/v1/decisions and get structured answers with probabilities, per-question refusals, and request-level citations — after live web research, not generated chat text. Each question may use at most 32,000 tokens including the shared state, and all questions in a request share one retrieval. It is BYOK-only through OpenRouter (wire parallel/decisions-fast:free), free there at $0, so add an OpenRouter key under Dashboard → BYOK and AnyRouter charges nothing. Decision models are free on every plan.

const res = await fetch("https://anyrouter.dev/api/v1/decisions", {
  method: "POST",
  headers: {
    Authorization: "Bearer " + process.env.ANYROUTER_API_KEY,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    state: { company: "Clay", website: "https://www.clay.com" },
    model: "parallel/decisions-fast",
    questions: {
      has_cli: { type: "noul", instructions: "Does Clay offer an official command-line interface?" },
    },
  }),
})
console.log(await res.json())
