Apr 30, 2026 Grok 4.3 is now available on [Vercel AI Gateway](https://vercel.com/ai-gateway). The model has a December 2025 knowledge cutoff and a 1M token context window. The model has improvements in accuracy, tool calling, and instruction following. To use Grok 4.3, set model to `xai/grok-4.3` in the [AI SDK](https://ai-sdk.dev/). ``` 1import { streamText } from 'ai';2 3const result = streamText({4 model: 'xai/grok-4.3',5 prompt: 'Analyze this dataset and summarize the key trends.',6}); ``` AI 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/docs/ai-gateway/capabilities/custom-reporting), [observability](https://vercel.com/docs/observability/ai-sdk-observability), [Bring Your Own Key](https://vercel.com/docs/ai-gateway#bring-your-own-key) support, and intelligent provider routing with automatic retries.
