SWE-bench Top-Ranked Reasoning

Multi-File Dependency & Race Condition Hunter

Unlike single-file snippets, GLM-5.3 parses entire project dependency trees. It tracks mutex contention and asynchronous leaks across dozens of files, producing clean git patches.

  • Tracks AST symbol definitions across entire repo
  • Exports industry-standard unified diff patches
  • Generates accompanying unit regression tests

Built for True Production Scale

Every architectural breakthrough is purpose-built to solve real-world memory bottlenecks and complex logic.

Only 48B active per token

753B Sparse MoE Architecture

16 routed experts · 48B active per token

Routes each token dynamically to Top-2 specialized experts, maintaining 753B parameter world knowledge while slashing computation overhead and latency by 70%.

99.8% Needle-in-Haystack Recall

1M Context & MLA KV Compression

Low-rank latent projection · 82% KV Cache saving

Combines Multi-Head Latent Attention (MLA) with adaptive RoPE extrapolation. Ingests 1M tokens with 99.8% Needle-in-a-Haystack recall, eradicating lost-in-the-middle degradation.

Self-healing Autonomous Loop

Native Tool-Calling & Sandbox Execution

Direct Bash, Docker & API self-healing loop

Executes Bash commands, Docker containers, and REST APIs natively without glue code, inspecting error traces and auto-refining patches until test suites pass green.

Zero-Regression Codebase Refactoring

AST-Aware Full-Repo Graph Reasoning

Symbol-level cross-file dependency graph

Embeds codebase ASTs and dependency graphs directly into reasoning attention, tracking type inference, imports, and interface contracts across hundreds of files without regression.
