GLM-5.2: Competitive Open Model for Long-Context Code Workloads

GLM-5.2: Competitive Open Model for Long-Context Code Workloads

Original: GLM-5.2 - The Open Model That's As Good As Opus!

Short summary

Z.ai's GLM-5.2 is a 1M-token open-weight MIT-licensed model that delivers solid performance for long-context, code-heavy, and token-intensive workflows at a fraction of frontier model costs. Creator Matt Wolfe tested it live in Cursor automation, web development, and compared against Opus 4.6, GPT-5.5, and Gemini 3.5. Viable for cost-sensitive projects where per-token efficiency outweighs absolute performance benchmarks.

  • •1M token context, MIT-licensed open weight, significantly lower cost than Opus/GPT-5.5
  • •Tested across Cursor automation, web development, and compared against top closed models
  • •Ideal for long-context and code-heavy workflows; not universally better than closed models
