Vercel adds MiniMax H3 Image models to AI Gateway
Vercel has added MiniMax H3 Image and MiniMax H3 Image Highspeed to AI Gateway, allowing users to generate and edit images through one API key without a separate MiniMax account. Both models support custom dimensions and aspect ratios, including 2K and 4K outputs.
- MiniMax H3 Image and H3 Image Highspeed are now available on AI Gateway.
- Both models generate and edit images through one API key.
- Custom dimensions and aspect ratios include 2K and 4K outputs.
- The Highspeed variant offers faster generation with the same image options.
- AI Gateway supports usage tracking and cost monitoring.
Image generation and editing in one API
The two MiniMax models can create images from text prompts or edit existing images. Vercel says users can generate a product visual or illustration, then send the resulting image back with instructions to change its colors, subjects, or composition.
The Highspeed variant provides faster generation while retaining the same generation and editing options. The models are available through the names minimax/minimax-h3-image and minimax/minimax-h3-image-highspeed.
Vercel’s example uses the AI SDK to generate a 2048x2048 PNG of a blue ceramic vase with wildflowers on a sunlit wooden table. A second request passes the generated image back with the instruction to change the vase to terracotta while keeping the flowers and setting.
Support for custom output sizes and existing API routes
MiniMax H3 Image and MiniMax H3 Image Highspeed support custom dimensions and aspect ratios, with outputs available at 2K and 4K. The AI SDK example sets the image size to 2048x2048 and requests PNG output through MiniMax provider options.
Both models also support the OpenAI-compatible /v1/images/generations and /v1/images/edits routes. Vercel directs users to its image generation guide for additional details and offers the models in its model playground.
What AI Gateway offers users
AI Gateway provides a unified API for calling models, tracking usage and cost, and managing access with one API key. According to Vercel, users can view requests and spending in their dashboard.
Vercel also says AI Gateway reflects provider pricing with no markup and no platform fee on inference. The company’s announcement gives users a way to access the two MiniMax image models alongside the other image models available on AI Gateway, while using the gateway’s shared access and monitoring features.
