Price receipt
We read Z.AI's own pricing page on Aug 18, 2026 and found GLM-5.3 listed with a price on the same row — that read is where the number above comes from, recorded as a new model. We keep the page text we read; its content hash is 997861e76a.
Overview
Z.AI's flagship model — a post-trained upgrade of GLM-5.2 (same MoE base) with major gains in coding and long-horizon agentic work. Text-only, 1M-token context, 128K max output; reasoning is always on with selectable effort. $1.40/$4.40 per 1M tokens; cached input $0.26. An open-weights release is announced to follow launch.
Capabilities
struck through = not supportedBenchmark performance
accuracy % · higher is betterWe hold no per-benchmark accuracy scores for this model yet, so it has no accuracy average. That is a gap in our coverage, not a sign the model is untested — independent evaluators often publish a composite index for a new model long before releasing its per-benchmark numbers. The percentile above is its standing across the independent composites below.
- AA Intelligence Index: 59.5 (Artificial Analysis composite across reasoning, knowledge and coding evals)
- AA Agentic Index: 59.1 (Tool use, planning, autonomy)
- AA-Omniscience Index: 14.3 (−100–100)
- GDPval-AA v2: 1769 ELO (Real-world work tasks, human baseline = 1000)
- Ranks #3 of 161 comparably-measured models by percentile score, across 4 independent measurements
- Ranks #58 of 161 comparably-tested models by normalized performance per dollar
