LetzAI API Skill for Claude

A Claude skill that enables AI-powered image and video generation using the LetzAI API.

What is This?

This repository contains a Claude skill that teaches Claude how to effectively use the LetzAI API. When this skill is active, Claude can help you:

Generate AI images using multiple base models (Nano Banana Pro, Flux2 Max, SeeDream)
Create AI videos from images using VEO, Kling, and Wan models
Edit images with context-aware AI editing
Upscale images to higher resolutions
Use custom trained models with the @modelname syntax

Usage Examples

Once the skill is installed, you can ask Claude things like:

"Generate an image of a sunset over the ocean using LetzAI"
"Create a video from this image with the camera slowly panning"
"Edit this photo to change the background to a beach"
"List my trained models and generate an image with @john_doe"
"Upscale this image to 4K"

API Overview

Endpoint	Purpose
`POST /images`	Generate images
`POST /videos`	Generate videos from images
`POST /image-edits`	Edit existing images
`POST /upscales`	Upscale images
`GET /models`	List custom trained models

All generation is asynchronous - poll the GET endpoints until status is "ready".

Available Base Models

Image Generation

Model	API Value	Resolutions
Nano Banana Pro	`gemini-3-pro-image-preview`	default, 2k, 4k
Flux2 Max	`flux2-max`	1k, hd
SeeDream 4.5	`seedream-4-5-251128`	2k, 4k

Video Generation

Model	API Value	Duration
Default	`default`	2-6 sec
VEO 3.1	`veo31`	8 sec
Kling 2.6	`kling26`	5-10 sec
Wan 2.5	`wan25`	5-10 sec

Custom Trained Models

LetzAI supports custom trained models for persons, objects, and styles. Use them in prompts with the @modelname syntax:

@john_doe on the beach at sunset
A product photo featuring @my_product
Portrait in @vintage_style aesthetic

Train models via the LetzAI web interface.
