Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | GLM-5-Turbo | Qwen3.5 Omni Plus |
|---|---|---|
| Input ($/M tokens) | — | $0.4 |
| Output ($/M tokens) | — | $4.8 |
Verdict. GLM-5-Turbo wins the overall benchmark matchup 1–0 across 1 overlapping categories, but raw benchmark score is only one input to the decision.
Pricing. Pricing varies significantly between these models — check the table above for the exact per-token rates. Many production workloads actually surface input-token cost (retrieval-augmented prompts, code-context windows), so factor both directions.
Strengths. GLM-5-Turbo is strongest on Intelligence Index (39.1). Qwen3.5 Omni Plus leads on Intelligence Index (31.3).
Speed. Speed data is incomplete for this pair; benchmark and price should decide.
Provider. Z AI and Alibaba sell to overlapping but distinct developer audiences: Z AI tends to ship frontier reasoning models with premium positioning, while Alibaba often prices more aggressively. Your existing vendor relationships, billing, and SLA preferences may matter as much as the raw numbers above.
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.
