xAI: Grok 3 Beta
xAI Grok 3 Beta supports tool use and function calling with a 131K context window, but without benchmark data its capability cannot be reliably assessed — it has also been superseded by newer Grok versions, limiting its appeal for current business deployments.

Grok 3 is the latest model from xAI. It's their flagship model that excels at enterprise use cases like data extraction, coding, and text summarization. Possesses deep domain knowledge in finance, healthcare, law, and science. Excels in structured tasks and benchmarks like GPQA, LCB, and MMLU-Pro where it outperforms Grok 3 Mini even on high thinking. Note: That there are two xAI endpoints for this model. By default when using this model we will always route you to the base endpoint. If you want the fast endpoint you can add provider: { sort: throughput}, to sort by throughput instead.
