As of August 3, 2026, Grok 4.6 is not yet released. Elon Musk announced a target launch of around August 7, 2026. It is a 1.5-trillion-parameter frontier model from xAI built on the same V9 foundation as Grok 4.5, with improved supervised fine-tuning and reinforcement learning.

What is new in Grok 4.6 versus Grok 4.5?

Grok 4.6 keeps the Grok 4.5 V9 foundation but adds significantly improved SFT and RL while maintaining the same speed and token efficiency. It aims to challenge models like Moonshot's Kimi K3 and Claude Opus 4.8, building on Grok 4.5's strengths in coding and office work such as Excel models and building apps from prompts.

When does Grok 4.7 come out?

xAI's Grok 4.7 is expected a few weeks after Grok 4.6, roughly a month later per Musk's late-July 2026 statements. That would place it around early September 2026, though xAI has not confirmed an exact date.

Quick Answer

Is Grok 4.6 Out Yet? August 3, 2026 Status

Published: August 3, 2026

The Short Answer

No — as of August 3, 2026, Grok 4.6 is not out yet. xAI’s Elon Musk set a target launch of around August 7, 2026, with Grok 4.7 expected a few weeks later (roughly early September).

What We Know

Model: Grok 4.6 is a 1.5-trillion-parameter frontier language model from xAI.
Foundation: It reuses the V9 foundation that also powered Grok 4.5, but adds improved supervised fine-tuning (SFT) and reinforcement learning (RL).
Efficiency: xAI is keeping the same speed and token efficiency as Grok 4.5 rather than trading it away for scale.
Targets: Grok 4.6 aims to challenge Moonshot’s Kimi K3 and Claude Opus 4.8 on capability.

What Grok 4.5 Already Did Well

Grok 4.5 (released July 8, 2026) excelled at coding and office work — building complex Excel models and producing functional apps from a single prompt. Grok models are known for real-time information access via X, a conversational tone, and social-network integration.

The Rollout Timeline

Grok 4.5 → July 8, 2026 (live).
Grok 4.6 → target ~August 7, 2026.
Grok 4.7 → expected a few weeks after 4.6.

What To Do Now

If you need Grok today, use Grok 4.5 ($2/$6 per MTok). If you can wait a few days, Grok 4.6 should land around August 7, 2026 — check xAI’s official channels for the confirmed rollout.
