GLM-5.1 Non-reasoning NEW

Z.ai's chat-tier counterpart

GLM-5.1 in non-reasoning mode — same 744B/40B-active MoE backbone as the reasoning sibling but answers directly without an explicit chain-of-thought. Lower latency, ~7 AA Intel points lower on hardest benchmarks. MIT licensed at $1.40/$4.40 hosted.

How are Intelligence, Speed & Cost bucketed?
Intelligence and Speed buckets are percentile ranks on Artificial Analysis. Cost buckets are fixed dollar thresholds keyed off output-token price ($/M out).

Why it matters

Demonstrates the "one weight set, two modes" pattern in the open-weights tier. Lowers the barrier to running both reasoning and chat modes from a single self-hosted deployment.

What it feels like

  • Direct chat-style answers without explicit reasoning traces — lower latency than the reasoning sibling
  • Still solid frontier-class on knowledge (GPQA 83.9%, MMLU-Pro), but ~7 AA Intel points behind the reasoning mode

Best use cases

  • Chat / customer support / writing where you want speed over chain-of-thought
  • Workloads where reasoning traces would be wasteful (translation, classification, summarisation)
  • Self-host with the same weights as GLM-5.1 Reasoning — switch modes via prompting

Tools to try

Not ideal for

  • Hardest math / coding tasks — switch to GLM-5.1 Reasoning for those
  • Multimodal / vision — text-only
