Image Generation

Steinkauz supports Image Generation as a Native Tool. When enabled and at least one Tool backend is eligible for the current chat provider, the model can create images from your description (for example “a sunset over the ocean”) using supported providers such as OpenAI and Black Forest Labs. Outputs are Generated Chat Files — the same Chat File registry used for uploads.

Tool backends

Workspace admins configure an ordered list of image backends under Settings → Native Tools. Each backend is a provider connection plus an image-capable model. The first backend that is allowed for the turn is used.

Each backend shows an Environment class inherited from its provider connection. When you chat on a higher-E provider, lower-E image backends are skipped so image generation does not egress to a weaker environment than the chat provider.

How it works

  • You chat as usual; when the model decides an image is needed, it calls the Image Generation tool (generateImage).
  • Configure one or more image backends under Settings → Native Tools. The chat Tools popover enables the tool when at least one backend is eligible for the current chat provider; otherwise it stays visible but disabled with a short reason.
  • Members do not pick the backend; the admin order and eligibility rules decide.
  • The generated image is shown in the Conversation via the shared Chat File preview, and remains available in Files after reload.
  • Variations of a prior result use the durable Chat File identity (filename / chat-file:), not expired display URLs.

Enabling Image Generation

  1. An admin (or you, if you manage Native Tools policy) adds and orders image-capable provider + model backends in Settings → Native Tools.
  2. In the conversation Tools popover, turn on Generate Image (disabled when no backend is eligible for the current chat provider).
  3. Tool policy modes (HITL / HOTL / HOOTL) continue to apply once the tool is available.

See Tool policies.

Provider and cost notes

  • Gateway: Image backends that use Gateway providers draw on your plan’s inference budget and the providers allowed by your Gateway provider configuration.
  • BYOK: Image backends use your configured providers and their pricing. Ensure you have an image-capable provider set up in BYOK Provider Configuration.
