Vercel has added MiniMax H3 Image and MiniMax H3 Image Highspeed to its AI Gateway, according to a company changelog. Users can generate images from text or edit existing images with one API key, without a separate MiniMax account.

The November 10 announcement brings the standard and faster variants into a gateway that provides an API for calling models, managing access and tracking usage and costs. Requests and spending can be viewed in the gateway dashboard.

Generation and editing

Both variants support custom dimensions and aspect ratios, including 2K and 4K output. Users can create an illustration or product visual from a prompt, then send the image back with instructions to change its colors, subjects or composition. The Highspeed version has the same generation and editing options, with faster generation, according to Vercel.

Vercel's model pages list support for up to 16 reference images and outputs of up to 20 megapixels for each variant. The supported output formats are JPEG, PNG and WebP. The models' playgrounds each offer an optional reference-image upload with a limit of up to four images.

Calling the models

To call the models, developers can use the identifiers minimax/minimax-h3-image and minimax/minimax-h3-image-highspeed. Both also support the OpenAI-compatible routes /v1/images/generations and /v1/images/edits.

Vercel's example uses its AI SDK to generate a 2048-by-2048 PNG image from a text prompt. It then passes the generated image back with a new instruction to edit it, using the same dimensions and output format.

Pricing and access

For the standard model, the gateway lists an input price of $2.30 and an output price of $3.80 per 1 million tokens. Highspeed has the same listed input price of $2.30 per 1 million tokens and an output price of $7.60 per 1 million tokens.

Vercel says AI Gateway reflects provider pricing without a markup or platform fee on inference. The model playgrounds bill usage to a team at API rates; users who have not made a payment receive $5 in credits every 30 days. Use of the models is subject to MiniMax's terms and privacy policies.

MiniMax's release

Separately, MiniMax announced H3-Image on November 11 as an open-weight image-generation model built on H3. The company said it was releasing the model weights and described support for text-to-image generation, reference-based generation and editing.

MiniMax claims H3-Image can generate a 4K image of 4096 by 4096 pixels in under 10 seconds. It also says the standard mode runs at 1.5–2 times the speed of mainstream alternatives, while Highspeed reaches 3–4 times their speed.

The model is also available through the MiniMax API Platform, MiniMax Code and Hailuo AI. For launch week, MiniMax is offering 50% off the standard price for image-generation requests at 4K resolution and above.
