Model provider

This app utilizes the OpenAI API for its AI capabilities. It is configured to use the following OpenAI models:

• Realtime Model (gpt-realtime): Higher quality conversational model with higher latency
• Code Model (gpt-4.1): General purpose GPT-4.1 model
• Transcribe Model (gpt-4o-transcribe): Optimized for speech-to-text transcription

The app leverages these models through the OpenAI Agent SDK to create a sophisticated voice-driven code generation experience with real-time audio processing and intelligent agent handoffs.

Deploy your own

You can deploy your own version of VibeCoder to Vercel with one click:

Running locally

You will need to use the environment variables defined in .env.example to run VibeCoder. It's recommended you use Vercel Environment Variables for this, but a .env file is all that is necessary.

Note: You should not commit your .env file or it will expose secrets that will allow others to control access to your OpenAI account.

1. Install Vercel CLI: bun i -g vercel
2. Link local instance with Vercel and GitHub accounts (creates .vercel directory): vercel link
3. Download your environment variables: vercel env pull

bun install
bun dev

Your app should now be running on localhost:3000.
