Copy any prompt below and try it yourself in the [playground](/models/open_router/qwen-qwen3-coder).

Repo Refactor

“Analyze this Python repository codebase. Identify inefficiencies in the data pipeline module across files. Propose refactored structure with type hints, async improvements, and generate pull request diff.”

Bug Hunt

“Examine this Rust CLI tool source. Trace memory leak in async runtime integration. Output fixed code, test cases, and explanation of root cause with stack traces.”

API Build

“Design FastAPI backend for user auth system. Include JWT, rate limiting, database schema in SQLAlchemy. Generate full server code with Docker setup and deployment script.”

Algo Optimize

“Implement efficient graph traversal for social network recommendations in Go. Optimize for 1M nodes using adjacency lists. Benchmark against BFS and provide Big-O analysis.”

For Developers
