Does Grok Bot really use Claude Opus 5.5? What users are seeing (Oct 2026)

Short answer: yes, according to the announcement and to usage logs users have posted. But you don't get to pick the model yourself.

What was announced

Around October 7, 2026, a wave of posts on X reported that Elon Musk said Grok Bot would stop relying only on xAI's own models and instead pick the best backend for each task, naming Claude Opus 5.5, Midjourney and Suno among them.

Elon Musk just turned Grok Bot into an AI model router. Instead of relying only on xAI's own models, Grok Bot will now select the best backend for each task—including Claude Opus 5.5 for reasoning, Midjourney for images, and Suno for music.

Grok Bot now picks the best model for each task, including Claude Opus 5.5. You don't switch models yourself. You just say what you want done.

The evidence: `claude-opus-5-5-low` in usage history

The most-engaged post in our research (112 likes, ~55.7K views) came from a Chinese-language account that updated Grok Bot and saw claude-opus-5-5-low appear in its call history.

(translated) Grok Bot really has started routing to Claude Opus 5.5 — after updating to the latest version you can see claude-opus-5-5-low in the call records.

The official @grok account replied (in Chinese) that this is genuine and that seeing claude-opus-5-5-low in the logs after updating is normal. Earlier, a user relayed that Cursor staff had said Grok Bot usage can list grok-bot-default / grok-bot-automation plus the real model names picked server-side for helper steps (@nateshreffler, second-hand).

What you can't do: choose Opus manually

(translated) Grok Bot does have Opus 5.5, but the bot calls it at random — you can't specify Opus 5.5!

Because routing happens server-side, results can vary run to run. One user compared a video made directly with Claude Code + Opus 5.5 against three made by Grok Bot and questioned whether they came from the same model (@Juvenlie23). If you need Opus every time, see the three ways to combine them deliberately.

The catch: Opus is token-hungry

Several users report that Opus-routed steps drain usage quickly — one saw claude-opus-5-5-low run 7 times in one minute on a one-sentence edit, roughly 190K tokens (@AiWeAi, translated). More in why your credits run out.

Unverified / changing fast: routing behaviour, labels and limits are reported by users and may change with any update. Check your own usage page.
