xAI / Grok 4.3
proDescription
Grok 4.3 is xAI's reasoning model, grouped in the Pro tier on Aymo, so it's included on a wider range of plans than the Max-tier models from other providers. It's positioned around value, aiming for strong reasoning and a large context window at a lower cost rather than topping every benchmark.
Chat with it for analyzing video directly, working across large codebases or long documents, and high-volume tasks where cost matters. It reasons through every request before answering, and it can pull in current information through built-in web search when a question needs up-to-date answers.
Because it always reasons before responding, it takes a bit longer to produce a first response than some faster models, so it fits better with tasks that can wait a few extra seconds than with instant back-and-forth chat.

Access depends on your Aymo AI plan. Grok 4.3 is available on supported paid plans. Check the latest pricing for details.
Yes, particularly when a question benefits from current, up-to-date information, since it can call on built-in web search as part of its response.
Select it from the model selector in any chat and send your prompt, with text, an image, or a video attached. Switch to a frontier model mid-thread any time a task needs deeper reasoning.
No. It runs on your Aymo plan with no separate xAI or SuperGrok account needed. If you'd rather use your own xAI account, BYOK supports Grok keys on qualifying plans.
Gemini 3.1 Pro is reported to score higher on reasoning and coding, while Grok 4.3 costs less and adds native video input. Both carry a large context window. Use Grok 4.3 for cost-sensitive and video work, and Gemini 3.1 Pro when a task needs top current performance.
