When generating images with Krea in Hermes Agent, choose based on your purpose and cost—don't default to the more expensive mode. v0.15.0 added two image generation providers, Krea 2 Medium and Krea 2 Large, and further plug-in FAL backends. For ordinary users, the key is not the name, but whether to pay more for higher quality.
How to choose is more practical
If it's just a draft of an article cover, social media accompanying images, or inspiration images, first use Medium to test directions; If you want more detailed portraits, product images, or main visual images, consider Large. Test prompts with small images first, then zoom in on quality, which is more cost-effective than generating high-spec images from the start.
Check three things before use
- In the Hermes Agent tool configuration, confirm that image generation is enabled.
- Confirm that the credentials required for Krea or FAL are configured.
- Clearly define the output purpose: drafts, covers, materials, or official commercial images.
Generating images isn't guaranteed in one go. The truly cost-effective way is to have Hermes first clearly write out the visual elements, style, scale, and prohibited content, then generate the first version. If the prompt is vague, switching to a more expensive model may not solve the problem.
When should it not be used?
If you need to strictly replicate brands, portraits, or materials with copyright risks, don't rely solely on generating images to launch directly. First, conduct manual review, and if necessary, use official materials or your own images. Krea is suitable for improving output efficiency, not for you to handle copyright and brand judgment.
