Warp just added Grok 4.6 to both its terminal app and the newly launched Warp Agent CLI. If you have an X Premium or SuperGrok subscription, you can connect right now by running /connect-grok inside Warp -- no separate API key needed.

What Grok 4.6 actually is

Grok 4.6 builds on Grok 4.5 with a particular focus on long-running agents and more ambitious interactive and visual work. It stays with complex tasks across many steps, whether researching a topic, analyzing information, working across a codebase, or turning an idea into a polished application.

The distinguishing bet in Grok 4.6 is capability gains through post-training, not scale. Where most frontier releases lean on a bigger base model, xAI held the 1.5T V9 foundation constant and poured the delta into supervised fine-tuning and reinforcement learning (RL). Supervised fine-tuning (SFT) shapes the model's behavior using curated examples; RL then pushes it further by rewarding good outcomes on hard tasks rather than just imitating examples.

Grok 4.6 underwent a longer supplemental training run than Grok 4.5, with curated model-generated data for reasoning and advanced technical concepts, high-quality engineering data, and an improved optimizer and training recipe.

How it benchmarks

Grok 4.6 achieves frontier intelligence across several agentic coding and knowledge work benchmarks, matching GPT-5.6 Sol on the Artificial Analysis Intelligence Index -- a composite score of nine benchmarks. Here is how it stacks up on the key evals:
