GLM 4.6. It’s Z.ai new flagship model. It is an update to GLM-4.5 and reaches near parity with Claude Sonnet 4.

Major improvement is the longer context window, expanded from 128K to 200K. It also shows significant improvements in coding. Z.ai aims to make it the best agentic coding model.

It is available for Claude Code, Opencode, Cline, and many others. Their Lite Plan, costing $3/month, provides up to 120 prompts every 5 hours, which should be about 3x the usage quota of the Claude Pro plan. I’m gonna try it today.

As I did for previous LLM releases on this blog, I won’t report the benchmarks but you can consult them on their official blog announcement.
