Image generation

Le Chat can generate and edit images directly in the chat interface. Describe what you need in plain language and get visuals you can use for presentations, product mockups, marketing materials, and more.

note

Le Chat uses Black Forest Labs models for image generation.

Activation

Click the + icon or type / in the chat window.
Select Tools then enable Image generation.

Image generation stays active for the current session. You can enable other tools at the same time.

Information

Daily generation limits apply based on your plan. For details, visit our pricing page.

Creating images

Describe the image you want in natural language. You don't need complex prompts or special syntax. Say what you're looking for and Le Chat handles the rest.

For the best results, include:

Subject: what the image shows.
Style: illustration, photorealistic, diagram, flat design, etc.
Constraints: aspect ratio / orientation.

Example prompt: "Create a flat illustration of a modern office interior with natural light and plants."

Editing images

You can refine generated images or edit existing ones in two ways.

Continue in the same conversation

After generating an image, describe the changes you want in a follow-up message. Le Chat understands you're referring to the previous image and produces an updated version.

Example: "Add a whiteboard on the back wall. Keep the lighting and color palette unchanged."

Upload an image in a new conversation

Start a new conversation, then upload an image using the + button the selecting Upload Files.

Describe the edits you want, and Le Chat generates a new version based on your instructions.

tip

This is useful when you want to pick up a previous result or edit an image from another source.

Prompt templates

Here are reusable patterns for common use cases:

Type	Template
Scene	Subject, style (flat/minimal), composition, aspect ratio
Photographic	Subject, photorealistic style, lighting type, lens, aspect ratio
Product mockup	Subject, studio shot, background, composition, aspect ratio
Diagram	Subject, clean lines, readable labels, accessible colors, aspect ratio
Presentation visual	Subject, slide-friendly composition, brand colors, minimal text, aspect ratio
Marketing material	Subject, target audience tone, style, brand guidelines, aspect ratio

Best practices

Be specific. "A photorealistic hero image for a fintech landing page, dark background, abstract light trails" produces better results than "make a banner."
Iterate. Treat the first result as a starting point. Refine with follow-up prompts until you're satisfied.
Pair with professional tools. Image generation works best alongside dedicated editing software for final adjustments like precise cropping, color correction, or brand overlays.
Download and reuse. Click the download button on any generated image to save it locally.

tip

For charts, graphs, and data visualizations, use Code Interpreter instead. It generates accurate visuals from your actual data using Python.

Limitations

Prompts or images that contain copyrighted or inappropriate content may be blocked by safety filters.
Fine details (small text, complex patterns) can sometimes be lost or altered during editing.

Canvas: create and refine presentations, documents, and code with AI.
Files upload: upload images and documents for Le Chat to analyze or edit.
