GLM-4.7 in Python: Build a Cheap Coding Assistant

Why everyone is suddenly switching to GLM-4.7

This week the AI dev feeds are full of one number: the price of a coding token. Z.ai (Zhipu) shipped GLM-4.7, an open-weight model that lands at 73.8% on SWE-bench Verified and 84.7 on the τ²-Bench tool-calling benchmark, putting its agentic coding roughly on par with Claude Sonnet 4.5. The twist is the cost. The weights are MIT-licensed and on Hugging Face, there is a completely free Flash tier on the API, and the paid coding plan starts at a few dollars a month. That combination is why GLM-4.7 is the model people are quietly swapping into Claude Code, Cline, and their own scripts right now.
