SpaceXAI's Grok lands on YappJam: token-lean multiplayer AI
SpaceXAI's Grok 4.5 and Grok Build join Claude, Codex, and Gemini in every YappJam room. Token-lean multiplayer AI that stretches your team's credits.
Now you can use SpaceXAI's Grok at YappJam!
Two Grok models from SpaceXAI
Grok 4.5, the flagship from SpaceXAI, the company formerly known as xAI, slots into the standard tier next to the strongest options from the other providers. Grok Build, the coding agent SpaceXAI open-sourced in July under Apache 2.0, is perfect for collaboration sessions and smaller tasks. If the open-sourcing put Grok Build on your list of things to try, you can now run it from a room without installing anything.
Available on Pro and Team plans today. One caveat before you go looking: the capped trial stays Anthropic-only, so running Grok means being on a paid plan. Plan details live on the pricing page.
Token economics is a multiplayer AI feature
A multiplayer AI session runs on iterations. A room full of people generates ideas faster than any one person prompting alone: someone wants the sidebar as a drawer, someone wants to see the empty state, someone wants the copy shorter. The cheaper each of those iterations gets, the further the same credit allowance goes.
This is where Grok earns its slot. By SpaceXAI's own measurements, Grok 4.5 finishes agentic coding tasks in around a quarter of the output tokens that comparable frontier models spend on the same benchmarks. Inside a room, that arithmetic is simple: more attempts within the same credit allowance. More throwaway variations of a screen, more experiments. Grok is tuned for sessions where your team tries eight things and keeps two, which describes most good prototyping sessions.
