GLM-5.1

GLM · Released 2026-04-07

Z.ai's April 2026 flagship for long-horizon agentic engineering. Official docs list text input/output, 200K context, 128K maximum output, function calling, structured output, context caching, MCP, and open weights under the MIT license.

Long-horizon coding and autonomous agent model for Claude Code/OpenClaw-style workflows when you want open weights from the GLM line.

Editor's note
GLM-5.1 is the GLM tool to watch for long autonomous coding runs. Z.ai's own benchmark claims are strong, but we keep the tool at solid until independent score rows are imported into VerdictPal's ledger.
Benchmark placements

Where GLM-5.1 places on each public benchmark source that publishes a row. Rank counts every model with a latest row in the same test — not a universal quality score.
