Repost Summary (English)

GLM-5 is positioned for complex systems engineering and long-horizon agentic tasks. Compared with GLM-4.5, the model scales from 355B parameters (32B active) to 744B parameters (40B active), while pre-training data expands from 23T to 28.5T tokens. The release also highlights DSA (DeepSeek Sparse Attention) to reduce deployment cost while preserving long-context capability.

On training methodology, the post emphasizes an asynchronous RL infrastructure called slime (open-sourced by THUDM) to improve reinforcement learning throughput and post-training iteration efficiency. The official claim is that GLM-5 delivers clear improvements over GLM-4.7 across reasoning, coding, and agent tasks.

A key narrative shift is from “chat” to “work.” The article presents end-to-end generation of .docx, .pdf, and .xlsx outputs as a core capability, and frames GLM-5 as usable across API, coding agents, chat interfaces, and local deployment workflows.

Key Metrics Snapshot

  1. Model and data scale: 355B -> 744B total parameters, 23T -> 28.5T pre-training tokens.
  2. Reported benchmark points in the post: HLE 30.5, SWE-bench Verified 77.8, SWE-bench Multilingual 73.3, BrowseComp 62, BrowseComp (w/ Context Manage) 75.9.
  3. Long-horizon benchmark example: Vending Bench 2 final balance $4,432.12, described as #1 among open-source models in the article.
  4. Adoption surfaces: Claude Code, OpenClaw, Z.ai (Chat/Agent), plus API and local inference.
  5. Open-source distribution: weights published on Hugging Face and ModelScope under MIT License (as stated in the source post).

Quick Takeaways

  1. The update is not only about larger model scale; it aligns coding and agentic workflows under one product direction.
  2. The product story emphasizes deliverables (documents and spreadsheets), not only dialog quality.
  3. For developers, the practical value is one model family across cloud API, coding agents, chat UI, and local serving.
