AI-Powered Web Development Levels Up as Vercel Debuts New v0 Model
Vercel has released its first dedicated AI model for v0 , marking a major step forward in its mission to bring AI-powered UI development to the mainstream. Known as v0-1.0-md , this new model is designed specifically for building modern web applications using natural language prompts.
The release comes amid growing interest in AI-driven design tools, with competitors like Google recently launching similar offerings such as Stitch and Gemma 3n , the latter built for running on low-end hardware like smartphones.
If you’re unfamiliar with v0 , it’s an open-source tool that launched in late 2023 as an invite-only beta. Its core promise is simple: describe a user interface in plain English , and let AI generate clean, ready-to-use front-end code — typically in React or Tailwind CSS.
What’s New With v0-1.0-md?
This latest model brings several powerful features to the table:
- Multimodal input support : accepts both text and images.
- Massive context window : up to 128,000 tokens, with a 32,000-token output limit.
- Pricing : $3 per million input tokens and $15 per million output tokens.
- Built-in tools : includes “auto-fix” for common coding errors and “quick edit” for real-time inline updates.
One standout feature is the OpenAI-compatible API , which makes it easy to integrate with existing tools like Cursor , Codex , or even custom apps already using OpenAI-style APIs. It also supports function calling , allowing developers to extend its capabilities further.
For developers eager to try it out, Vercel offers access through the Vercel AI Playground , where you can test different prompts and see how the model responds in real time.
How to Access the Model
Currently, the v0 API and v0-1.0-md model are in beta , and require a Premium or Team plan on Vercel with usage-based billing enabled.
To get started:
- Get an API key from v0.dev .
- Send POST requests to
api.v0.dev/v1/chat/completions. - Authenticate using a bearer token.
There are some initial limits in place — around 200 messages per day and context window restrictions — but these can be increased upon request.
