Grok 4.6
xAI's August 12, 2026 model for coding, agentic tasks and knowledge work. It builds on Grok 4.5 with supplemental training, regenerated supervised fine-tuning trajectories and agentic reinforcement learning. At launch, xAI reported DeepSWE v1.1 65.9% and APEX-Agents 57.5% at high reasoning effort. It accepts text and images, produces text and has a 500K-token context window, with low/medium/high/xhigh reasoning effort. Standard xAI API input/output rates are $2/$6 per MTok (input/output) below 200K prompt tokens and $4/$12 at or above 200K; cached input is $0.50/$1 respectively. Microsoft Foundry availability was announced August 26, 2026.
