GLM 4.5

By Z.ai
Model family: GLM
GLM 4.5 advances the GLM line with steadier step-by-step analysis and clearer instruction following while keeping latency predictable for production. It handles multi-document prompts and extended chats without losing the thread, switches comfortably between Chinese and English, and tackles practical software tasks from generation to debugging and refactoring. The model integrates neatly with retrieval so answers can be grounded in your data, returns schema-true JSON when workflows require strict formatting, and calls tools to search, run code, or query services inside an agent loop. Responses stream for responsive UX, and policy alignment keeps outputs safe and controllable for customer-facing apps. For teams that need visual reasoning, the VL variants accept images alongside text for document, chart, and screenshot understanding. In practice, GLM 4.5 serves as a dependable default for enterprise copilots, analytics explainers, and repo-aware code assistants, offering a pragmatic balance of accuracy, speed, and deployment ease.

    I have been using z.ai for two weeks for web development and it's mind blowing for me. What amaze me more is its capacity to understand my existing code with very little context and suggest -or just write- lot of improvement. I did some test to compare it with ChatGPT, Claude, etc. but the results were no even close. And I keep pushing the limits but it doesn't even blink.
