The models
- Grok 4 - xAI's strongest reasoner.
- Grok 3 - the balanced daily driver.
- Grok 3 mini - quick and light for simple asks.
- Grok 4.7 - expected soon.
Grok is xAI's model family, and it gives Magnus a noticeably different flavour - direct, a little irreverent, and current. It's a popular pick for a second or third agent whose personality should stand apart from the main one.
Grok models are part of your included credits (or add your own xAI key, starting with "xai-", in Settings). Combine it with the humor slider turned up and a debate partner agent on Claude - the roundtables get lively.
