xAI: Grok 3 Beta · fastrouter

Grok 3 Beta is xAI's flagship model featuring specialized domain expertise in finance, healthcare, law, and scientific fields. This enterprise-focused solution delivers exceptional performance in data extraction, code generation, and text summarization tasks. Released in 2025, the model particularly excels in structured tasks and achieves superior results on challenging benchmarks like GPQA, LCB, and MMLU-Pro, consistently outperforming the smaller Grok 3 Mini even when the latter operates at high thinking levels. Grok 3's sophisticated knowledge architecture makes it particularly valuable for professional and technical applications requiring deep contextual understanding in regulated industries. The model offers dual deployment options: a standard endpoint optimized for quality and a fast endpoint prioritizing throughput, allowing users to select the appropriate performance profile based on their specific application requirements.
