Real-World Coding Test
We gave all three models the same prompt: "Build a REST API in Python with FastAPI that handles CRUD for a todo list with SQLite."
GLM 5.2
Generated a Coding Plan first (5 files), then complete working code with tests. Minor import issue in test file.
4.2/5
Claude Fable
Extended thinking produced clean architecture. Most complete output with error handling and migration scripts.
4.6/5
Kimi 2.7
Fast output, working code, but no tests and minimal error handling. Good for quick prototypes.
3.9/5
Our Recommendation
- Choose GLM 5.2 if: you need a cheap coding API, want local deployment, or are running high-volume agentic tasks
- Choose Claude Fable if: you need the absolute best quality and budget is not a constraint
- Choose Kimi 2.7 if: speed is critical and you want a Chinese-developed alternative to GLM
