Grok (xAI)
grok-4.5, grok-4.20-multi-agent, grok-4-fast-reasoning and more via xAI
Grok is xAI's family of large language models, built for advanced reasoning and multi-agent workflows. Grok 4.5 is the current flagship — a coding- and agent-focused model xAI positions as roughly comparable to Claude Opus 4.7 at lower cost and higher speed. The lineup also includes a multi-agent-optimised model and two fast-reasoning variants designed for high-throughput agentic pipelines.
