What GLM-5.2 Changes for Long-Horizon Coding

What GLM-5.2 Changes for Long-Horizon Coding

Short summary

GLM-5.2 offers a 1M-token context window and IndexShare architecture that makes long-horizon coding tasks more practical by reducing compute costs. Flexible effort levels let developers trade latency for reasoning depth based on task needs. MIT license and ecosystem support (Transformers, vLLM, SGLang) enable production deployment if costs align with your context size.

  • GLM-5.2 enables large-context coding tasks (1M tokens) with IndexShare architecture reducing compute by 2.9×
  • Flexible effort levels let teams trade latency for reasoning depth per task type
  • MIT license and ecosystem support enable production deployment at scale
