19 items3 sourcesupdated 5h agotrend 5

Z.ai released GLM-5.2, an MIT-licensed open-source model designed for long-horizon software engineering tasks, achieving near-parity with proprietary frontier models on coding benchmarks. The model supports a 1M-token context window with up to 131K output tokens and ranks just behind Claude Opus 4.8 on FrontierSWE while edging out GPT-5.5.

  • Scores 1% behind Claude Opus 4.8 and 1% ahead of GPT-5.5 on FrontierSWE long-horizon coding benchmark
  • Supports 1M-token context window with up to 131,072 output tokens for agentic workflows
  • MIT-licensed open weights model, positioning it as cost-effective alternative to proprietary coding models
  • Marked substantial capability leap over predecessor GLM-5.1 in long-horizon task performance
  • Available via unified Model API on Z.ai platform and as local deployment option
