AI Chat Assistant (ChatGPT Clone)
A production-style chat assistant with token-by-token streaming and persistent conversations.
Problem
A chat demo only feels like a product once replies stream, conversations persist, and the user can stop or regenerate a response.
What I built
- Built a production-style assistant with React/TypeScript, FastAPI, and LangGraph serving Groq-hosted gpt-oss-120b.
- Implemented token-by-token streaming, persistent conversations, stop/regenerate controls, and Markdown rendering.
Result
A live assistant on Groq-hosted gpt-oss-120b that streams token by token, keeps conversations, and supports stop/regenerate and Markdown.
