This project generates Twitter (X) bios for you using Together AI.

This project uses both Qwen 3.5 9B and GPT OSS 20B with streaming to generate a Twitter bio. It constructs a prompt based on the form and user input, sends it to the Together AI API, then streams the response back to the application. Qwen 3.5 9B has thinking disabled for fast direct responses. GPT OSS 20B is a reasoning model that thinks before responding, shown with a "Thinking..." indicator.

If you'd like to see how I built an older version of this app with GPT 3.5, check out the video or blog post.

1. Create a .env file, make an account at Together AI, and add your API key under TOGETHER_API_KEY
2. Run the application with npm run dev and it will be available at http://localhost:3000.
