## Using individual image models
Image generation defaults to FLUX 2 Klein 9B for speed. Override per-call by passing the model ID to the `image_generate` tool:
The model is chosen once, in `hermes tools` → Image Generation, and stored in `config.yaml` as `image_gen.model`. Every `image_generate` call uses that stored model — the tool has no model parameter, so there is no per-call override. Leave it unset and Hermes uses FLUX 2 Klein 9B.
| Model | ID | Best for |
|---|---|---|
| FLUX 2 Klein 9B | `fal-ai/flux-2/klein/9b` | Fast, good default |
| FLUX 2 Pro | `fal-ai/flux-2-pro` | Higher fidelity FLUX |
| Z-Image Turbo | `fal-ai/z-image/turbo` | Stylized, fast |
| Nano Banana Pro | `fal-ai/nano-banana-pro` | Google Gemini 3 Pro Image |
| GPT Image 1.5 | `fal-ai/gpt-image-1.5` | OpenAI image gen, text+image |
| GPT Image 2 | `fal-ai/gpt-image-2` | OpenAI latest |
| Ideogram V3 | `fal-ai/ideogram/v3` | Strong prompt adherence + typography |
| Recraft V4 Pro | `fal-ai/recraft/v4/pro/text-to-image` | Vector-style, graphic design |

The **Nous Subscription** row has one model picker that lists every model once. The stored id decides which gateway serves the request: a native Krea id (`krea-2-medium`, `krea-2-large`, `krea-2-medium-turbo`) goes to the Krea gateway, a FAL catalog id goes to FAL, and any other id goes to Nous Portal. The selection is still just `image_gen.provider: nous` plus the model id.
The set evolves — `hermes tools` → Image Generation shows the current live list.
**Krea 2** (Medium, Large, Medium Turbo — up to 10 style-reference images, optional Enhance upscale) and the Nous Portal image models sit in that same picker rather than behind rows of their own. They need a paid subscription — the free tool pool funds the FAL models only. The Krea-via-FAL ids (`fal-ai/krea/v2/...`) stay on the direct FAL.ai row.
**Krea 2** (Medium, Large, Medium Turbo — up to 10 style-reference images, optional Enhance upscale) and any Nous Portal image models sit in the same **Nous Subscription** model picker rather than behind rows of their own. Every model appears once; picking a Krea id (`krea-2-medium`, …) sends the request to the Krea gateway instead of FAL, and the selection is still just `image_gen.provider: nous` plus the model id. Krea and Portal models need a paid subscription — the free tool pool funds the FAL models only.
Model ids, speeds, and prices live on the [Image Generation](./image-generation.md#supported-models) page. The set evolves — `hermes tools` → Image Generation shows the current live list.
