KaibanJS v0.22.0 🚀

🤖 xAI Grok Model Support (Including Grok-4)

KaibanJS now supports the latest Grok-4 model from xAI — bringing advanced LLM reasoning into your multi-agent workflows.

Alongside Grok-4, this release also adds compatibility with additional xAI variants: - grok-3 - grok-3-mini - grok-3-mini-fast

Whether you're building lightweight prototypes or full-scale agentic systems, KaibanJS now offers native support for all current xAI model versions.

🌐 How to Use

Add @langchain/xai to your project and configure the model via llmConfig:

:::ts
const agent = new Agent({
  name: 'XAI Analyst',
  role: 'Use Grok to summarize and report on live sports events',
  llmConfig: {
    provider: "xai",
    model: "grok-4", // or "grok-3-mini-fast"
  }
});

📚 Playground + Storybook Update

We’ve added a new Grok-enabled story to the React Playground (SportNewsTeam.stories.js). This allows developers to explore Grok-powered workflows visually — no setup required.
