Grok guideVerified

xAI's Grok Imagine. Newer entrant with a distinct humour-forward aesthetic. Useful for meme work and pop-culture-aware content.

Strengths

Distinctive aesthetic — feels different from the Veo / Kling crowd.
Good at irreverent / humorous beats.
Generous on what it'll generate (less restrictive than Veo).

Weaknesses

Quality is a tier below the established flagships.
Documentation is sparse — prompting is more trial-and-error.
