GLM 4.7 Flash (Free)

GLM 4.7 Flash is built on a Mixture of Experts architecture with approximately 30 billion parameters and an A3B activation pattern, meaning only a subset of the model activates during each forward pass. This design choice trades off raw depth for computational efficiency, making the model particularly well-suited for developer workflows that demand quick turnarounds. The architecture targets local coding tasks and agent-based applications where speed and responsiveness matter more than exhaustive reasoning.

The model serves as a practical entry point for developers handling straightforward coding tasks, document formatting, and quick lookups. While it deliberately sacrifices depth to prioritize speed, it holds its own on simple completions and formatting work. Complex debugging, multi-file refactoring, and sophisticated agentic workflows remain areas where premium models outperform it, but GLM 4.7 Flash provides a solid free option for rapid prototyping and lightweight tasks where cost matters more than exhaustive analysis.
