SpaceXAI announced Grok 4.6 on August 12, 2026, an upgrade to Grok 4.5 at the same price. It scores 61 on the Artificial Intelligence Analysis Index, matching GPT-5.6 Sol, and shows notable gains in long-running agent tasks and coding benchmarks. The model emphasizes task continuation and converting vague ideas into working applications.
SpaceXAI's Grok 4.6, announced August 12, 2026, is built on Grok 4.5 with a focus on long-duration agent tasks and interactive visual processing. On the Artificial Intelligence Analysis Index, it scored 61 points, matching OpenAI's GPT-5.6 Sol. The model recorded strong results on coding benchmarks: 1753 on GDPVal-AA v2, 69.9% on CursorBench 3.2, and 61.3% on FrontierCode v1.1, second only to Claude Fable 5 Max.
Training involved additional learning over a longer period than Grok 4.5, with regenerated SFT trajectories and model-based filtering. SpaceXAI highlights task continuation capability, positioning the model to turn vague product ideas into working first versions. Safety measures were strengthened, with extensive pre-deployment testing.
