Grok Imagine Prompts & Examples

Grok Imagine is xAI's general-purpose image model and AetherWave's default for ambiguous-intent generation requests. Billed as a flat request rather than per image, currently returning 2 images per call. Fast generations (~30s) and an AtlasCloud failover wired to the same model so a KIE outage does not drop the request - that leg returns one image at the same price. Note it returns JPEG, not PNG, so outputs carry no alpha channel.

This page collects prompts that consistently produce strong output from Grok Imagine when called via the AetherWave MCP server. Each example is structured to highlight what makes the prompt work, so you can adapt the pattern to your own scenes.

Prompt structure that works

For Grok Imagine, the prompts that perform best follow a predictable structure:

• Subject first: lead with the main thing in the frame ("vintage Roland synthesizer", "musician in a rain-soaked alley")
• Style and lighting next: how it should look ("photorealistic", "35mm film grain", "soft purple bokeh", "golden hour")
• Composition and aspect: framing cues ("close-up", "wide shot", "16:9", "magazine-quality")
• Mood and atmosphere last: the emotional pull ("moody", "cinematic", "dreamlike")

How to use these prompts

Once you have the AetherWave MCP installed in Claude Code, just paste any of the prompts above. The agent will call aetherwave_generate_image with model: "grok-imagine-t2i" and return the asset URL.

When to pick Grok Imagine

Grok Imagine is the right model when your prompt matches its strengths: multi-variation image generation.

For other intents, the AetherWave MCP rubric in aetherwave_generate_image's description routes the agent to the right model automatically. Run aetherwave_list_image_models from Claude Code to see the full live catalog.

Comparison

vs gpt-image-2-t2i at 9 cr / 1 image: Grok bills 6 cr per request and returns 2 images (about 3 cr/image) as JPEG; GPT Image 2 returns 1 stronger image at 9 cr as PNG. Use Grok to explore cheaply; GPT Image 2 when the result is the deliverable, or when you need transparency.

How long should a Grok Imagine prompt be?

30 to 80 words is the sweet spot. Lead with the subject, follow with style and composition, finish with technical specs.

Can I use these prompts directly via Claude Code?
