Z.ai / 智谱 model evolution

  1. GLM-5

    The GLM-5 generation advances systems engineering and long-running agent tasks.

    Original release ↗
  2. GLM-5 → GLM-5.1

    The update advances engineering planning, terminal tasks and sustained execution; outcomes still depend on the task and tool configuration.

    Original release ↗
  3. GLM-5.1 → GLM-5.2

    A 1M-token context and selectable reasoning effort accompany further long-task and coding improvements.

    Original release ↗
  4. GLM-5.2 → GLM-5.3

    Post-training advances complex engineering and agent tasks on the GLM-5.2 base; the flagship still takes text input.
