Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | QwQ 32B | GLM-4.5-Air |
|---|---|---|
| Input ($/M tokens) | $0.66 | $0.17 |
| Output ($/M tokens) | $1 | $0.98 |
Verdict. GLM-4.5-Air takes the aggregate benchmark matchup 1–0 across 1 categories. Real workloads usually care about a handful of specific tasks — see the per-benchmark table above.
Pricing. Both models sit in the budget bracket for output-token pricing. At 1.0× the per-million-token cost, GLM-4.5-Air is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). GLM-4.5-Air makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. QwQ 32B is strongest on Intelligence Index (13.4). GLM-4.5-Air leads on Intelligence Index (16.7).
Speed. Speed data is incomplete for this pair; benchmark and price should decide.
Provider. Alibaba and Z AI sell to overlapping but distinct developer audiences: Alibaba tends to ship frontier reasoning models with premium positioning, while Z AI often prices more aggressively. Your existing vendor relationships, billing, and SLA preferences may matter as much as the raw numbers above.
Workload cost. Workload scenarios (per million requests at 30M input + 15M output tokens): QwQ 32B costs $34.80 ($418/year); GLM-4.5-Air costs $19.80 ($238/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): QwQ 32B ≈ $5.30/run, GLM-4.5-Air ≈ $2.81/run. At agent/realtime scale (200M input / 100M output per million requests): QwQ 32B ≈ $232/run, GLM-4.5-Air ≈ $132/run. GLM-4.5-Air becomes more attractive at higher volume — the absolute per-token pricing difference compounds when you ship at scale.
Recommendation. Both models have legitimate use cases — the right answer depends on whether you are optimizing for benchmark ceiling, latency, or unit cost. Start with the cheaper / faster model, evaluate against your specific task, and only switch if the upgrade shows a meaningful lift.
Data from Artificial Analysis API — 12 benchmarks
GLM-4.5-Air is cheaper overall. Its blended price (3:1 input/output ratio) is $0.37/M tokens vs $0.74/M for QwQ 32B.
