Poe API

Grok-3

xAI's February 2025 flagship release representing nearly state-of-the-art performance in several reasoning/problem solving domains. The API doesn't yet support reasoning mode for Grok 3, but does for https://poe.com/Grok-3-Mini; this bot also doesn't have access to the X data feed. Supports 131k tokens of context, uses Grok 2 for native vision.
