What is GLM-5.2?

GLM-5.2 is Z.ai’s flagship foundation model for long-horizon tasks. Z.ai positions it for project-scale engineering contexts where the model must retain architecture, API contracts, repository conventions, and earlier decisions while taking work from requirements to a deployable product. It accepts text input and produces text output.

  • 1M-token context: works across large codebases, technical documentation, requirements, and project history
  • 128K maximum output: supports detailed implementations, reviews, and long-form engineering deliverables
  • Long-horizon coding: plans, implements, verifies, and closes multi-file tasks in stages
  • Engineering discipline: follows architectural boundaries, dependency constraints, build processes, test requirements, and repository conventions
  • Agent integration: supports multiple thinking modes, streaming, function calling, context caching, structured JSON output, and MCP tools

Z.ai highlights GLM-5.2 for codebase audits, large refactors, API migrations, mobile debugging, Mini Program development, research reproduction, and other workflows where context continuity and reliable follow-through matter.

Why use GLM-5.2 on Atoms?

  • Turn requirements into implementation: move from a product goal and technical constraints into a structured build plan
  • Keep project context connected: work across specifications, code structure, API contracts, and existing engineering decisions
  • Coordinate multi-step execution: organize product, engineering, review, and validation tasks around one shared outcome
  • Review before release: inspect the live result, resolve issues, and verify behavior against the original requirements
  • Deploy and retain ownership: publish the finished product and export the code to GitHub when needed

Multi-Agent AI Team

PM, Engineer, and Designer work together to turn your prompt into a complete product.

Ship in Minutes, Not Months
