Grok 4.20 lands on Vercel AI Gateway in Reasoning, Non-Reasoning, and Multi-Agent variants.
Grok 4.20, xAI's newest flagship model, is now available on Vercel AI Gateway in three variants. The vendor describes it as offering industry-leading speed, agentic tool calling, a low hallucination rate, and strict prompt adherence.
- Grok 4.20 Non-Reasoning: optimized for speed and direct responses
- Grok 4.20 Reasoning: extended thinking for complex problem-solving tasks
- Grok 4.20 Multi-Agent: built for multi-agent orchestration and collaboration
To use it, set the model to xai/grok-4.20-non-reasoning-beta, xai/grok-4.20-reasoning-beta, or xai/grok-4.20-multi-agent-beta in the AI SDK. AI Gateway also tracks usage and cost and can be viewed on its model leaderboard.
